Learning is the process by means of which we discover regularities in the world. Memory is the process that we hold on to that information over our life time. We are in large part who we are because of what we learned and what we remember. Synaptic plasticity is considered to be the biological substrate of learning and memory. One of the goals of my research is to develop models (and modeling methods) to better explain consequences of synaptic modification. In previous experimental and modeling studies, it has been found that synaptic strength changes based on spike-timing. One form of plasticities, so-called spike-timing-dependent synaptic plasticity (STDP) is able to automatically balance the synaptic strength and leads to stable distribution of synaptic conductances. Here one of the key questions I ask is: under STDP, how do the synapses adapt to new sensory experiences so that the new distribution of synaptic weights is formed with the old one being consolidated and not erased ? If STDP is not enough, what are the roles of other forms of plasticity ?
