The direct pathway flows from the cerebral cortex to the striatum to the internal segment of the globus pallidus, which synapses with the thalamus. The indirect pathway takes a similar route, but first detours from the striatum to the external segment of the globus pallidus, then the subthalamic nucleus, and then back to the internal segment of the globus pallidus. The net effect of the transient

The main idea of evolutionary psychology is that the structures in the brain that are responsible for memory are similar to one another (Nairne, 2010). It is likely that memory systems evolved due to pressures or problems that our ancestors faced (Nairne, 2010). This suggests that memory mechanisms probably come from solving problems in the environment our ancestors once lived in (Nairne
