NEUROBIOLOGY AUXILLARY GLOSSARY ACETYLCHOLINE – A neurotransmitter in both the brain and peripheral nervous system* (PNS). In the brain it helps regulate memory, whilst it controls the actions of skeletal and smooth muscle within the PNS. ACTION POTENTIAL – An electrical phenomenon which occurs when a neurone is activated and temporarily reverses the electrical state of its interior membrane from negative to positive. An electrical charge travels along the axon to the neurone’s ending (terminal) where it triggers the release of a neurotransmitter* and then disappears. ADRENALINE (U.S. - Epinephrine) – A hormone released by the adrenal medulla* and a neurotransmitter acting at the level of the autonomic nervous system and the brain. ADRENAL CORTEX – The outer layer of the adrenal, a small endocrine gland located near the kidney. It produces and secretes several horm...

PSYCHOLOGY PART 1: CORE Biological level of analysis Outline principles that define the biological level of analysis. 1) Behavior can be innate, because it is genetically based. Evolution may play a key role in behavior. 2) Animals may be studied as a means of understanding human behavior. 3) There are biological correlates of behavior. Cognitions, emotions and behaviors are products of the anatomy and physiology of our nervous and endocrine system. Explain how principles of the biological level of analysis may be demonstrated in research. 1) Correlational studies: Study by Buss, who hypothesized that across cultures, men will prefer to marry younger women because of greater reproductive capacity and women will place greater value on a potential mate's earning potential to provide survival advantages. This evolutionary hypothesis was tested in 37 cultures by sending out questione...
