Working memory
hideWorking memory is a theoretical construct within cognitive psychology as to the structures and processes used for temporarily storing and manipulating information in short-term memory. Many theories exist both as to the theoretical structure of working memory as well as to the role of specific parts of the brain involved in working memory. Most research identifies that the frontal cortex, parietal cortex, anterior cingulate, and parts of the basal ganglia are crucial for its functioning. The neural basis of working memory mostly comes from lesion experiments in animals and functional imaging upon humans.
