The physiology of working memory has been studied using
1)brain lesions in monkeys,
2)neural recording from monkeys, and
3)brain imaging in humans.
what do the results of each of these procedures tell us about working memory and the brain?

1. Brain lesions in monkeys.

Explanation:

Researchers back in the 1930s found that lesions in the prefrontal cortex of monkeys reduced the ability of their working memory to function properly in space-related situations.

Conversely, neural recording from monkeys implies that researchers somehow recorded the neural activity from the monkeys when it is the brain of the monkeys that "records" or remembers the actions in the experiment. Working memory has to do with what was previously teferred to as "short-term memory" but with a change in meaning. Working memory now implies the manipulation of information rather than simply storing it, commonly only for a few seconds.

i really wish i could answer this question for you
