Hebb Activity between presynaptic terminal and postsynaptic neuron strengthens the connection between them “Neurons that fire together, wire together.” o Long term potentiation (LTP) Long term increase in neuronal excitability in response to a particular presynaptic input • The Hippocampus o Perforant path sent to the Dentate gyrus; synapse at the granule cell; sent to the area of the hippocampus called the CA3; synapse at the CA3 pyramidal cell; sent to the CA1 and synapses at the CA1 pyramidal cell; sent out of the hippocampus o EPSP by stimulation of Schaffer collaterals (LTP)...
