Summary : In most animals the sense of smell is essential for their survival. For instance, the detection and recognition of odor molecules by the olfactory system allows animals to find sources of food, to detect the presence of predators, and ultimately to find potential mates. Using a combination of imaging and electrophysiology recording techniques, our lab studies how the neuronal circuits of the olfactory bulb participate in the processing of olfactory information.

Summary : My research investigates the foundations of social cognition, through developmental studies with infants, young children, and adults. In particular, my work focuses on early reasoning about intentional agency, social interactions, communication, and social relationships. In complement with research investigating how we represent and learn about our social world, I also examine how our social understanding combines with different social concerns to motivate children's own behaviors, such as attempts to affiliate with others. I employ a variety of behavioral methods in this pursuit, from looking time and eye-tracking methodologies to measures of children's active helping and communicative behaviors.

Summary : The brain encodes rules, which we use to guide our behavior. However, life is often unpredictable, and in some situations we need to adaptively modify our behavior in the face of change. I study the interaction of rule encoding areas in the prefrontal cortex, with downstream habitual responding areas in the striatum. Investigating how this circuit leads to flexible behavior will lead to a better understanding of dysfunction in humans with psychiatric disorders affecting attention, set-shifting, behavioral flexibility and cognitive rigidity.

Summary : The Section on Synaptic Transmission investigates the synaptic and biophysical mechanisms that enable neurons to encode and process information. Specifically, we study mechanisms that enable computations in neural circuits of the auditory system. The general question we address is how local circuit interactions shape a neuron's response to physiologically realistic patterns of synaptic inputs, thereby encoding relevant features of sounds. Our experimental approach combines electrophysiology and optical techniques to study synaptic transmission and plasticity in the cochlear nucleus and auditory brainstem. These studies contribute to our understanding of how sensory stimuli are represented by neuronal activity and will enable improvements in treatment of hearing disorders.

Summary : I am interested in the development and consequences of social learning in early childhood. Specifically, my research program explores the nuanced interplay between two critical components of early learning: the capacity to learn important information about the world by making inductive inferences on the basis of limited evidence, and the ability to flexibly and selectively learn from others. By investigating this interplay across several important areas of learning—causal reasoning, inductive generalization, categorization, and normative judgment—as well as over the course of development, I hope to generate broad conclusions about how early cognitive development is fundamentally shaped both by the social context in which it occurs, and by children’s developing social cognitive capacities.

Summary : The NeuroTheory Lab at University of Maryland operates at the interface of neuroscience experiment and theory, using experiments performed by collaborators to ground and validate conceptual frameworks and analytical methodology, and theory to guide experiment design and analysis. Our projects are largely focused on the visual system, where we are studying visual computation in the context of simulated "natural vision" experiments across multiple visual areas (retina, LGN, cortex). There are also projects in other areas including the auditory system, as well as studying synaptic plasticity and brain development. A key component of these projects is the study of how the computations performed by neurons explicitly use time: for example in the temporal patterns of spikes, the relationship to brain rhythms, and particular patterns of activity across neurons.

Summary : My lab is interested in the genetic and cellular basis of development of the mammalian amygdala in both normal and pathological conditions. Despite an extensive understanding of amygdala function and anatomy, currently little is known regarding the development of this complex structure and how misdevelopment contributes to human neurodevelopmental disorders such as autism and autism spectrum disorders. Using techniques of modern mouse genetics and mouse models of neurodevelopmental disorders, we are examining the genetic and cellular processes underlying the generation of amygdala neuronal cell diversity and functional connectivity. The ultimate goal of these studies is to understand the link between brain developmental events and the assembly of the mature amygdala at a genetic, cellular, structural, and functional level.

Summary : Our research focuses on the mechanosensory hair cells that are the receptor cells of hearing and balance. We are interested in the molecular signals that regulate the survival, homeostasis, and death of these cells. Human hair cells must survive and function for up to a century in order to transduce sound energy into the neural signals of hearing. During this time, the hair cell may encounter multiple toxic stimuli, including excessive sound and/or exposure to therapeutic drugs with ototoxic side effects. We are examining the signals that mediate the survival and death of hair cells under stress. Our studies indicate that heat shock protein (HSP) induction is a critical stress response that can promote survival of hair cells exposed to major stressors. Our studies are broadly divided into two groups: 1) those aimed at understanding the molecular mechanisms underlying the protective effects of HSPs and 2) those aimed at translating our findings into clinical therapies to prevent or reverse hearing loss.

Summary : With grant support from DoD, we measure the changes, at the level of the activity of single neurons over many weeks, correlated with the induction of tinnitus (ringing in the ears) following noise trauma. Specifically, the research uses behavioral measures to verify the emergence of tinnitus post-trauma, chronic electrode arrays to measure and compare the activity of large populations of single neurons before and after induction of tinnitus, and post-mortem immunocytochemical methods to uncover permanent changes in the brain. The Ear Lab wants to explore new drug delivery or stimulation methods that might prevent the induction of, or provide relief from, tinnitus, a common affliction that has received very little scientific attention until recently.

Summary : At the Aphasia Research Center we study language production and comprehension of individuals with aphasia using methods such as language analysis, reaction time measures, grammaticality judgments, and treatment efficacy. In particular, we are interested in the following issues: What neural mechanisms are involved in the processing and production of verb inflections and sentences (both in normal and aphasic individuals, using magnetoencephalography)? Why do some individuals with aphasia experience difficulty in producing verb inflections? Do these individuals have parallel deficits in comprehending verb inflections? What variables, if any, influence the production of verb inflections in aphasic individuals? Do aphasic individuals experience difficulties in encoding and/or expressing temporal information? Why do some aphasic individuals experience difficulties in sentence production? How can findings from psycholinguistic literature aid in designing treatment programs for aphasic individuals?

I continue to work on issues in the theory of control and reflexivization but have also recently considered how to integrate bound pronominalization within a move-centered account. This work has a general minimalist flavor to it. However, at the level of implementational detail it differs in important ways from the work currently flying the minimalist banner. Indeed, it resonates more with earlier minimalist work of the mid 90s than with the most recent proposals of Chomsky (1998, 1999, 2000).

Summary : Current research focuses on understanding how the brain constructs networks of interacting regions (i.e., neural networks) to perform cognitive tasks, especially those associated with audition and language, and how these networks are altered in brain disorders. These issues are addressed by combining computational neuroscience techniques with functional neuroimaging data, obtained using fMRI, PET, or MEG. The network analysis methods allow us to evaluate how brain operations differ between tasks and between normal and patient populations. This research will allow us to ascertain which networks are dysfunctional, and the role neural plasticity plays in enabling compensatory behavior to occur. A unique aspect of our research is that most of the experiments we do are linked to our modeling, in that these experiments are performed to either acquire data for developing our models or else for testing them.

Summary : Language development involves more than just learning words or syntactic rules. During this process, do children consistently generate the same kinds of interpretations as adults do? When they fail to do so, what do these differences reveal about nature of development? My research explores these questions by examining how the moment-to-moment changes that occur during language processing influence the year-to-year changes that emerge over the course of language development. This work relies on the use of eye-tracking, an innovative method that yields implicit and fine-grained measures of children's interpretation, and focuses on changes in development that occur during the early school-aged years.

Summary : My research has spanned a range of topics in vision. My primary focus has been on the problem of how to recognize objects in images. This is a central problem in vision that I find particularly fascinating because it lies between concrete, lower-level vision problems and central cognitive systems that attempt to tie semantics to the world. It is also a critical problem in many applications in multimedia and robotics. I have also done quite a bit of work in the computational and psychological study of perceptual organization. This is the lower level problem of how to identify the surfaces of potential objects before recognizing them. I see perceptual organization as integral to the recognition process, and in part my work attempts to show how these two problems can be unified.

By interfering with development, we aim to understand how disruption of early circuit function gives rise to neurological disease. To do this we use in vivo and in vitro physiological and imaging approaches such as single and multielectrode recordings, patch clamp recordings, laser-scanning photostimulation, 2-photon Ca-imaging of large networks, optogenetics, and computational modeling.

Summary : My research seeks to understand the human computational system that supports the real-time interpretation and reinterpretation of sentences. In particular, central to revising initial processing commitments is 'cognitive control.' Cognitive control refers to the regulation of mental activity to guide and support flexible behavior, enabling individuals to bias the selection of appropriate over inappropriate information during goal-directed tasks. Data from behavioral, neuroimaging, and neuropsychological studies suggest shared mechanisms in prefrontal cortex (PFC) that support regulatory functions across a range of tasks, including working memory, attention, and language processing. Using a multiple-method approach, my research asks whether a cardinal function of PFC-supported cognitive control is to override early misinterpretations during sentence processing to prevent comprehension failure.

Summary : Dispositionally anxious individuals-those who tend to express anxiety too intensely or in response to inappropriate cues-are vulnerable to developing anxiety and other psychiatric disorders. These disorders are common, debilitating, and often treatment resistant, underscoring the need to understand the mechanisms linking dispositional anxiety to psychopathology. To this end, our laboratory uses brain imaging, electrophysiological techniques, peripheral physiological measures, and behavioral assays in adults and children to address three broad questions: 1) What is the nature of the large-scale neural circuit underlying variation in anxiety? 2) How does anxiety influence attention, memory & cognitive control? 3) What mechanisms underlie the inhibited behavioral profile characteristic of anxious individuals? Our goal is to understand how variation in anxiety contributes to psychopathology, discover novel endophenotypes, and set the stage for developing improved interventions.

Summary : Dr. Wittenberg's research interests presently lie in using transcranial magnetic stimulation (TMS) and functional imaging to understand motor cortical reorganization following stroke and in designing testing new methods for neurorehabilitation. He is the principal investigator in a study of precisely timed motor cortical stimulation to increase useful plasticity during robotic arm therapy. He also uses TMS and functional MRI to detect changes in motor representation, resting-state brain connectivity, and task-specific activation.

Summary : Proper assembly of neural circuits requires newly born neurons to migrate to their final location and establish appropriate functional activity. The Cellular and Developmental Neurobiology Section conducts research on 1) Cell lineage, Neuronal Migration and Axonal Targeting and 2) Mechanisms underlying Neuronal Activity. Our focus is on development and regulation of GnRH neurons, cells essential for reproduction. GnRH neurons originate in nasal regions and migrate into the brain. In reproductively mature animals, these neurons release peptide in a pulsatile fashion. Disruption of this system results in reproductive dysfunction, as is seen in patients with Kallmann Syndrome. Approaches used: cre/lox mice, transgenic lines, imaging, nasal explants, videomicroscopy, calcium imaging, electrophysiology, immunocytochemistry, in situ histochemistry, single-cell PCR, and subtractive cDNA screening.

Summary : The goal of our research is to identify genes that are important in the development of the inner ear. The inner ear is structurally complex. Any perturbations in its patterning during development will undoubtedly lead to functional deficits. Therefore, a good understanding of the normal development of the inner ear at a molecular level will help to decipher malformations resulting from mutations. The chicken and the mouse are the two animal models currently being used in our laboratory. In the chicken, we have employed various embryonic manipulations such as implantation and transplantation techniques to address the normal development of the inner ear. To investigate the function of a specific gene of interest during inner ear development, we use avian retrovirus vectors as a method of gene transfer for gain or loss of function experiments. In collaboration with other laboratories, we are also characterizing several knock-out mice that have developmental inner ear defects.

Summary : The overarching goal of our laboratory is to find out how insect auditory systems are able to acquire and process acoustic information to yield complex, adaptive behaviors. We are especially interested in the evolution of hearing in insects, and have chosen the very unusual praying mantis ear as a model system.

Summary : The focus of my research is on bilingualism. A major question of investigation is the effect of the age at which bilingual individuals acquire their second language on their proficiency in both of their languages. In this research we make use of current research techniques in speech perception and acoustic analysis of speech.

Summary : Research in our lab focuses on understanding the neural correlates of human cognitive function using intracranial recordings captured during epilepsy surgery and deep brain stimulation surgery. In both cases, our lab seeks to record single unit spike activity and local field potential activity directly from the human brain of neurosurgical patients as these patients participate in different cognitive tasks, and to use computational techniques to establish how these signals correlate with different human behaviors. The larger goal of this work centers around understanding the neural code mediating such cognitive processes as memory, decision, and attention. By exploring these questions, we hope to not only gain an understanding of how the human brain processes and relays information, but to potentially open up new possibilities to directly communicate with the brain's complex networks.
