LTP Major neocortical inputs and outputs of the hippocampal formation are channeled through Entorhal cortex ( neurons in the entrohinal relay incoming information to the granule cells ( through a bundle of axons known as the perforant path ( project axons to CA3 of hippocampus ( CA3 branch into 2 directions ( 1. terminates into CA1 ( forms synapses with the dendritic spines of other cells ( 2. other branch travels through the fornix to structures in the basal forebrain ( CA1 pyramidal cells connects with their counterparts on the opposite side of brain( info projected to targets outside hippocampus ( info is sent to sebicular output (axons project our of hippocampus to accumbens & entorhinal cortex INSTRUMENTAL CONDITIONING FLOW CHART! STIMILUS (sight of a lever) ( Neural circuit that detects a particular stimulus (reinforcement strengthens this connection) ( neural circuit that controls a particular behavior ( behavior (lever press) (when rat presses lever, it receives food) ( reinforcing stimulus (food) ( reinforcement system ( process strengthens a connection between neural circuits involved in perception and those involved in movement CLASSICAL CONDITIONING FLOW CHART! 1000-Hz tone ( neuron in auditory system ( synapses T weak ( excitatory postsynaptic potential (ESPS) produced in the dendrite of motor neuron is too small to make that neuron fire 1000-Hz (puff of air in eye ( neuron in somasensory system ( synapse T strengthened ( causes eye to blink
