Document Summary
Mackenzie (reading material nolte textbook: chapter 23; chapter 24: 616-628) Memory: storage and retrieval of information occurs in stages the hippocampus and limbic system play a role in memory processing. There are chemical and structural processes involved. limbic system structures are involved. Established for a few seconds to a few minutes. It has a limited capacity about 7 8 chunks of information. Considered a holding bin for data that we may or may not want to come back to. For the most part, short term memory is a preliminary step for long term memory. Involves both changes in the pre and post ca concentrations and secondary messengers these change the result of electrical activity. long-term memory (ltm) Short-term memory: working memory established for only a period of seconds involves changes in pre and post-synaptic calcium concentration. Changes increase synaptic strength (albeit for short term).
