Dictionary of Biological Psychology
An inadequate supply of OXYGEN to the brain. Brain structures are particularly vulnerable to interruptions in oxygen supply. Areas most affected include the HIPPOCAMPUS, GLOBUS PALLIDUS and the WATERSHED AREAS OF CORTEX such as the occipito-parietal and occipito-temporal regions, and medial temporal cortex.
Common causes of cerebral anoxia include suffocation, strangulation, CARBON MONOXIDE poisoning, cardiac arrest and improper ANAESTHETIC use. Posterior cerebral structures can be particularly susceptible to anoxic events, leading to AGNOSIA and AMNESIA, and failures in EXECUTIVE FUNCTIONS are also a possible outcome.
