Physiology of memory


Memory occurs when information is stored in the brain by changing the basic sensitivity of synaptic transmission between neurons due to previous activity of the said neuron. The new pathway is then referred to as memory traces. Memory traces are found in all levels of the central nervous system including spinal cord, suggesting memory mechanisms occur at all levels.

Different types of memories undergo different processes in the brain depending on whether they induce pleasure or pain. Pleasure memories are facilitated while pain memories are inhibited so that we tend to remember more, positive things than negative. Memories are classified in relation to time.
