Peri Kurshan, Ph.D. Assistant Professor, Dominick P. Purpura Department of Neuroscience Studying synaptic development and function using C. elegans. Defects in the proper development and function of synapses lead to neurodevelopmental disorders such as Autism and Intellectual Disability, however the molecular mechanisms underlying these processes are still largely unknown. We use the nematode C. elegans, which has a simple and stereotyped nervous system and whose connectome has been fully mapped out, to investigate the conserved molecular mechanisms of synapse development. In particular, we study how presynaptic components including cell adhesion molecules, active zone scaffold proteins, calcium channels and synaptic vesicles arrive at the synapse and form a mature and fully functional presynaptic compartment. We combine the power of worm genetics with high resolution imaging and optical physiology readouts to elucidate the role of key molecules. These approaches have led to discoveries suggesting that the role of synaptic cell adhesion molecules such as Neurexin may be different than initially hypothesized, as we have shown that its role in presynaptic development is independent of extracellular activation and downstream of other initiating factors.

Purpura Department of Neuroscience I concentrate on providing modern electron microscopic techniques to explore the details of normal and mutant anatomy of the nematode C. elegans. I generally work in collaboration with other C. elegans labs who require our expertise to solve interesting problems in cellular and developmental biology, including sensory reception, synaptic connectivity, mechanisms of cell death, and aging of the nervous system Peri Kurshan, Ph.D. Assistant Professor, Dominick P. Purpura Department of Neuroscience Studying synaptic development and function using C. elegans. Defects in the proper development and function of synapses lead to neurodevelopmental disorders such as Autism and Intellectual Disability, however the molecular mechanisms underlying these processes are still largely unknown. We use the nematode C. elegans, which has a simple and stereotyped nervous system and whose connectome has been fully mapped out, to investigate the conserved molecular mechanisms of synapse development. In particular, we study how presynaptic components including cell adhesion molecules, active zone scaffold proteins, calcium channels and synaptic vesicles arrive at the synapse and form a mature and fully functional presynaptic compartment. We combine the power of worm genetics with high resolution imaging and optical physiology readouts to elucidate the role of key molecules. These approaches have led to discoveries suggesting that the role of synaptic cell adhesion molecules such as Neurexin may be different than initially hypothesized, as we have shown that its role in presynaptic development is independent of extracellular activation and downstream of other initiating factors.

Korey Department of Neurology Research in our laboratory examines neural mechanisms underlying auditory perception of speech, music, and other complex sounds at the cortical level. Of particular interest are the neural processes that allow the brain to perceptually separate spectrally and temporally overlapping sounds in complex acoustic environments, e.g., speakers’ voices at a cocktail party. These neural processes are studied via electrophysiological recordings of neural activity in auditory cortex of awake, behaving non-human primates.

Davidoff Department of Neurological Surgery My laboratory aims to characterize neural circuits supporting the appraisal of naturalistic visual stimuli, and how these valuable stimuli capture attention, at times derailing ongoing goal-directed behavior. The human experience also involves learning about “good” and “bad” stimuli and making choices to overcome aversive stimuli and events, which can involve new learning or cognitive mechanisms of control or reappraisal. We use the opportunity afforded by human neurosurgical procedures to record single-unit activity from the amygdala and cingulate cortex. Behavioral modeling, measurements of autonomic state, and eye-tracking provide a rigorous framework for the analysis of single-unit activity and reveal how neurons in the human brain contribute to our unique social, emotional, and cognitive experience.
