Summary
The amygdala is part of the brain that assigns emotional content to our sensory world and dysfunction of the amygdala is responsible for many anxiety-related disorders. Many anxiolytics, like valium, act on receptors in the amygdala. In this project we will study circuits in the amygdala that are modulated by anxiolytics. These studies will provide essential information in the understanding of anxiety disorders and help in developing drugs to treat these disorders.
Dendritic Activity And Neuronal Output During Sensory Perception

Summary
A fundamental goal of neuroscience is to understand how sensory experiences arise from activity in the brain. This is no easy feat and is the basis of the research in this proposal. Here, using cutting edge recording techniques, the activity of brain cells within the cortex will be measured during sensory-based behavioural tasks. This research will provide insight into therapeutic approaches to numerous brain diseases where sensory processing is compromised.
Persistent Firing In Cortical Interneurons: Mechanisms And Potential Anticonvulsant Role

Summary
The normal brain treads a fine line between too much electrical activity (epilepsy) and too little (sedation). We have discovered a class of brain cell that seems to behave like a sentinel, monitoring brain activity for signs of epilepsy. If a seizure occurs, this cell switches on an electrical brake that dampens excess activity. In this project we will study how this brake works and whether it really can inhibit seizures. Our research may lead to better treatments for epilepsy.
