Document Summary
What is long-term potentiation (ltp) and its characteristics. Learning is a process by which relatively long lasting changes occur in behavioral potential as a result of experience. Encoding: stimulus event encoding (interpreted stimulus event) memory trace (encoded interpretation + prior knowledge) Retrieval: retrieval environment (specific request[s] + environment cues) retrieval cue (interpreted retrieval environment) retrieved memory trace remembered event (interpreted trace) 3 parts: dendrites, cell body (or soma), axon(s) Receptors in the postsynaptic neurons pick up the neurotransmitter. The neuron (cid:1123)fires(cid:1124) if the total electrical charge exceeds a threshold. The neuron is the fundamental structural and functional unit of the nervous system. Cajal proposed the possibility of synaptic plasticity: the strength and/or # of synaptic connections changes as a result of experience. Donald hebb said that, cells that fire together, wire together. Makes small changes in the connection weights b/t a sender & a receiver unit.
