ST memory and task complexity
Short term memory brain circuits operate differently depending on the complexity of the task.
- Two distint processes are involved in ST memory. One is termed 'silent' where information is stored; the other displays increased neural activity and involves the manipulation of information.
“Short-term memory is likely composed of many different processes, from very simple ones where you need to recall something you saw a few seconds ago, to more complex processes where you have to manipulate the information you are holding in memory. We've identified how two different neural mechanisms work together to solve different kinds of memory tasks.” - David Freedman, PhD, professor of neurobiology.
