  • Descrição: A crucial role for working memory in temporary information processing and guidance of complex behavior has been recognized for many decades. There is emerging consensus that working-memory maintenance results from the interactions among long-term memory representations and basic processes, including attention, that are instantiated as reentrant loops between frontal and posterior cortical areas, as well as sub-cortical structures. The nature of such interactions can account for capacity limitations, lifespan changes, and restricted transfer after working-memory training. Recent data and models indicate that working memory may also be based on synaptic plasticity and that working memory can operate on non-consciously perceived information. Working memory emerges from dynamic interactions among several component processes, by recurrent loops and synaptic modulation in prefrontal and cortical/sub-cortical networks. These interactions vary according to task demands and relevant long-term memory representations and account for variation in working-memory functioning.
