Metaplasticity at Single Synapses

Speaker: Adam Frank

Summary of the talk: Neuronal activity is known to modify NMDA receptor subunit composition; and, NMDAR subunit composition has significant effects on NMDAR synaptic currents. Given the importance of the NMDAR in the induction of LTP it is not surprising that altering NMDAR currents, by altering subunit composition, has demonstrated effects on the induction of LTP. Lee et al. now demonstrate these phenomena at the level of single synapses in cultured hippocampal neurons: altering spontaneous activity changes the ratio of NR2B to NR2A subunits and effects both NMDAR synaptic current as well as LTP induction threshold. These findings are presented in the context of metaplasticity, where prior activity at a synapse effects the subsequent ability of the synapse to undergo plasticity.

The reorganization and reactivation of hippocampal maps predict spatial memory performance

Speaker: Walt Babiec

Summary: The hippocampus has place cells that preferentially fire at a particular location of spatial arena. Dupret et al. report that place fields remapped as a result of goal-directed spatial learning and that sharp wave/ripple reactivation events seen during memory consolidation predicted the strength of subsequent spatial memory.

Lateral and laminar flow of information in cortical circuits.


Speaker: Dean Buonomano

Summary: The basic flow of activity through cortical circuits is not understood, nor is the computational function of each step in the cortical circuit. It is known that lateral interactions play two critical roles: sharing information between neighboring areas and, conversely, competition through lateral inhibition. This paper from the Scanziani lab shows that both lateral competition and facilitation can be observed in vivo and in vitro.
