We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Spike-Timing-Dependent Plasticity of Synaptic Inputs @ Northwestern University
[unreadable] DESCRIPTION (provided by applicant): Project Summary: Spike timing dependent plasticity (STOP) is a mechanism whereby the strength of an activated synapse is modified based on its correlation with postsynaptic action potentials. There is much interest in STOP, as it provides a biological substrate for the postulated Hebbian mechanism of memory, upon which many contemporary experimental and theoretical models of learning are based. Here, we propose to study the intracellular correlate of associative memory. STDP has largely been studied by evoking action potentials with somatic current injections. We will study the mechanisms of STDP elicited by correlated activation of separate synaptic pathways, using electrophysiological whole cell recordings. STDP of a weak synaptic input to the apical dendrites of CA1 pyramidal neurons will be paired with action potentials generated by strong synaptic inputs to either proximal apical or basal dendrites. We will then investigate the mechanisms of STDP with calcium imaging and dendritic recordings to directly measure the dendritic events that mediate STDP with synaptic stimuli. This study will investigate the underlying mechanisms of synaptically driven STDP. Relevance: There is a significant body of evidence that plasticity an important mechanism in learning, memory, and cognitive function. The proposed studies here will investigate mechanisms of synaptic plasticity for physiological inputs, and how plasticity is modulated. A fundamental understanding of the basic mechanisms of plasticity at the cellular level will ultimately contribute to a better understanding of cognitive function, and facilitate the development off therapeutic treatment of cognitive dysfunctions.
