Statistical constraints on synaptic plasticity.
The synaptic basis for learning suggested by Hebb (1949), Marr's theory (1969) for motor learning in the cerebellum, and Stent's mechanism (1973) for synaptic depression in visual cortex depend on coincidences between presynaptic and postsynaptic events. Two statistical constraints on this class of mechanisms will be examined here: the first concerns the problem of synaptic saturation from chan...
متن کاملEffects of visual deprivation on synaptic plasticity of visual cortex
TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...

متن کاملThe effect of ketamine on synaptic transmission and synaptic plasticity in CA1 area of rat hippocampal slices
The effect of ketamine (1-100 µM), which has NMDA receptor antagonist properties, on synaptic transmission and long-term potentiation (LTP) in CAl area of rat hippocampus was examined in vitro. Field potentials were recorded in pyramidal cell layer following Schaffer collateral stimulation. Primed-burst stimulation (PEs) was used for induction of LTP. The amplitude of population spiks (PS) was ...
