PSY397H5 Lecture Notes - Lecture 6: Pipette, Low Frequency
Document Summary
Hebb father of memory mechanisms and ltp; Epsd is higher; this increase is induced by the single tetanus; Every dot is a response to a single pulse of identical electrical stimulation; the only difference between the bottom ones and the top ones is that the top ones are preceded by the tetanus. The pulse itself does not change; but the epsd responses change only based on the tetanic stimulation; Even hours after they are firing with higher epsd; seems like they have remembered; The strengthening or weakening of the connections can be done in many ways; All of those little branches are synapses; this is just a very small part of the neuron and there are so many synapses; Recording electrode usually glass pipette filled with electrolyte. Recording configuration and typical responses in a hippocampal. Stimulus artifact electric pulse running through the liquid; Nodes of ranvier really slow down conduction; so overall, the axon.
