Researchers have found that certain types of specializations on nerve cells called "spines" are depleted as a person ages, causing cognitive decline in the part of the brain that mediates the highest levels of learning. These spines receive an important class of synapses that are involved with the process of learning.

Spontaneous Activity Found In The Idling Brain
Researchers have uncovered new information about portions of the brain that spontaneously activate together when a person is at rest. The latest research demonstrates how the interactions of certain brain regions at rest become more distributed as a person ages. It is believed that an increased understanding of normal brain function will allow researchers to better characterize mental disorders s
