PSY290H5 Lecture Notes - Lecture 8: Donald O. Hebb, Synaptic Plasticity, Hebbian Theory
Document Summary
Learning is reflected by changes in the brain. Changes in functionality (fmri) measure blood flow in certain regions of the brain while performing certain tasks. Increase or decrease in synapse (hebbian synapses increase in synaptic activity) The hippocampus is one part of a broad memory system (important for transferring episodic details to other areas of the brain) There needs to be some kind of change between neurons more connections being made. Over 100 different mechanisms have been proposed to support learning.

Thought that if learning happens on a behavioural level, and that the brain is the seat of all behaviour (the origin of behaviour), change sin behaviour should be reflected in changes in neurons.
