Neural dynamics and brain function

The brain's ability to think, perceive, and remember depends not just on which neurons fire, but on the precise timing and coordination of their activity across large networks. Researchers in this area study how rhythmic patterns of neural activity — particularly fast oscillations in the gamma range — emerge from the interplay between excitatory neurons and inhibitory interneurons, and how that synchrony allows distant cortical regions to communicate and cooperate. These dynamics appear to underlie fundamental cognitive operations, including how sensory information is encoded and how working memory holds information briefly in an accessible state. Open questions center on how the brain maintains stable yet flexible synchronization across scales, and how disruptions to these rhythms contribute to conditions such as schizophrenia and Alzheimer's disease.
