Expertise and Research Interests
What is the relationship between brain activity and conscious thought? Like other difficult questions in science, a good model system is needed so that this question can be investigated. I have chosen epilepsy as a model system for investigating consciousness, because in epilepsy there is a spectrum of levels of consciousness, which may be explained in terms of different states of brain activity. Ongoing studies in my laboratory include experiments to explore electrophysiologic and network mechanisms common to seizures and other states of impaired consciousness. In particular, we are investigating the role of subcortical structures such as the thalamus and brainstem in the propagation and behavioral manifestations of seizures. Current projects include in vivo and in vitro multimodal electrophysiology and fMRI recordings from animal models of epilepsy, human neuroimaging (fMRI and SPECT) and intracranial EEG studies in relation to behavior during seizures.
Other related themes in my laboratory include:
1. computational methods for neuroimaging data analysis.
2. fundamental relationships between neuroimaging signals and underlying brain physiology.
3. molecular mechanisms of epileptogenesis, and strategies to prevent or cure epilepsy.

Other Expertise
In my earlier work, I investigated cellular mechanisms of synaptic plasticity and the role of neuromodulation in memory and learning using simple in vitro networks of Aplysia neurons. These studies layed the foundation for my current investigations involving larger scale networks that also show plastic changes and memory effects.
I have recently completed a textbook of neuroanatomy titled "Neuroanatomy Through Clinical Cases" published by Sinauer Assoc., Publ. http://www.neuroexam.com/43.html
Teaching activities include serving as Director of Medical Studies in Clinical Neuroscience at Yale School of Medicine.

Future Research
New directions for my laboratory during the coming years include the use of the latest advances in neuroimaging techniques to investigate seizure networks in humans and animal models, virtual reality behavioral testing during seizures, and molecular techniques to prevent epileptogenesis.
