Greatest psychologist = nova scotia donald hebb = what fires together, wires together . When two cells are active at same time, the strength of connection between them is enhanced . It takes two: depolarization, nmda n-methyl dispartate. Glutamate has several kinds of receptors: ampa causes depolarization to post-synaptic cell, nmda receptor critical for causing long lasting changes to make post synaptic cell to have larger depolarization in the future.
