The brain is capable of dynamically changing in response to sensory input, resulting in learning and memory. Synapses, the connections between neurons, are the structural landmark that is physically altered upon learning. I am interested in the cellular and molecular mechanisms of neuronal plasticity, especially in the various subsets of inhibitory neurons. For my PhD, I investigated the changes in both excitatory and inhibitory synapses in the living rodent brain using fluorescently tagged proteins and imaging with two photon microscopy. With my co-authors, I discovered that inhibitory synapses of visual cortex are capable of assembling and disassembling on a time course of days, and that altering inputs results in greater plasticity and loss of inhibitory synapses. I am currently continuing this work and looking at ways to label presynaptic inhibitory inputs.
