BIOLOGICAL FOUNDATIONS OF BEHAVIOR

The electrical properties of neurons have been known for more than a century, but we have only recently begun to understand the chemical processes involved in ...

NEURAL CONNECTIONS: Some You Use, Some You Lose

They have studied this process most carefully in the brain's outer layer, or cortex, which is essentially ...

Abnormal gray matter aging in chronic pain patients
... There is no doubt that the brain undergoes structural changes due to normal conditions like aging. For example, normal aging is characterized by cortical gray matter (GM) atrophy (Bergfield et al., 2009; Blinkov and Glezer, 1968; Good et al., 2001; McGinnis et al., 2011; Morrison and Hof, 2007; Sowe ...
