My main interests are in understanding the mechanisms involved in the generation of cortical network activity. In particularly we are keen to understand the role of different types of network oscillations e.g. theta (4-12 Hz) and gamma (30-80 Hz) frequency oscillations in the hippocampus and prefrontal cortex. These oscillations are important for many higher cognitive functions including learning, memory and attention. I am also interested in understanding how these oscillations are modulated by the brain's different neuromodulator systems including dopamine and noradrenaline.
In my lab we use a combination of in vitro electrophysiological and in vivo approaches in rodents to study cortical network oscillations and their modulation by monoamine neurotransmitter systems. We are also involved in a large multi-group project using EEG recordings and optogenetics to record and manipulate the abnormal cortical activity occurring in epilepsy. I have close collaborations with many other researchers within the Institute of Neuroscience and long standing collaborations with Prof Nancy Kopell (Boston Uni) and Prof. Ed Boyden (MIT) and with Professor Miles Whittington (York Uni).
We are currently working on a number of projects elucidating the role of network oscillations in the hippocampus and prefrontal cortex. Changes in these key brain areas are implicated in many diseases such as schizophrenia, Alzheimer's disease, and dementia with Lewy bodies. We are currently investigating changes in the monoamine systems and network oscillations in a variety of animal models of these diseases.
