Additional Information

Brief Non-technical Description of Research (for layperson):

The focus of my lab is to understand the role of a type of glial cell called astrocyte in the development of synchronous activity in the brain. Nerve cells or neurons communicate with each other by generating action potentials or spikes. In the awake brain the overall spiking activity of the hundred billion neurons appears random. However, when in deep sleep or under anesthesia, the spiking activity becomes synchronized between various regions in the brain. This type of synchronous spiking is thought to be necessary for the development and maintenance of the functional organization of the brain – neurons that fire together wire together! Synchronized spiking activity also occurs during epileptic seizures – epilepsy is currently an intractable disease with no cure. Our central hypothesis is that astrocytes play a central role in the synchronization of neurons in the brain. Our preliminary data using pure neuron only and mixed (astrocyte and neuron) cultures on multi-electrode arrays (MEAs) demonstrates that astrocytes are necessary for synchronization of the spiking activity. We are currently dissecting the molecular pathways within astrocytes that are necessary for the synchronization of neuronal spiking activity.
