My research is focused primarily on understanding how chronic stress causes depression. In my laboratory we address this issue by electrophysiological and molecular techniques to detect the alterations of synaptic plasticity and its underlying mechanisms in the fundamental brain regions related to emotional control in animals subjected to chronic stress.
I am also interested in how emotional disorders influence single neuron processes information. Since the majority of synaptic inputs of neuron happen on the dendrites of the neuron, my research will focus on how emotional disorders alter the functions of different type of ion channels that are located on the dendritic harbor of the neuron and carry out the information flow.
