PSYC 106 Lecture Notes - Lecture 19: Donald O. Hebb, Negative Relationship, Hebbian Theory
Document Summary
Donald hebb: learning much change in the synapse. Hebbian mechanism: increase in synaptic strength between pre and postsynaptic neuron when the two neurons are active simultaneously. Increase in synaptic strength = the effect of the neurotransmitter on the postsynaptic neuron becomes larger! Pavlov: we can think of this in terms of neurons in these brain areas! Happens with explicit and implicit memory, even though pavlov is ex of implicit. Measure the baseline response of post synaptic neuron to single pulse onto axons of. The postsynaptic neuron response to a single pulse is now much larger than the the presynaptic neurons. (you are zapping the presynaptic neurons to measure the postsynaptic neurons) Tetanus: administer 1-10 seconds of intense, high frequency stimulation of pre-synaptic neurons (bzzzzzzzjzhjhlhjhzzzjhlkjhzzzz) purpose is to increase the amount of time in which there is simultaneous activity bw pre and post neuron] Ltp is the effect of the nt on the postsynaptic neuron becomes larger.
