Exercise increases levels of a chemical involved in brain cell growth, which bolsters the release of the "feel good" hormone dopamine, a new study shows. Dopamine is known to play a key role in movement, motivation, and learning.

The neurotransmitter dopamine has often been linked to pleasure-seeking behaviors and making stimuli paired with rewards (e.g., food, drinks) valuable. Nonetheless, the processes through which this key chemical messenger ...
A study from UCLA neurologists challenges the idea that the brain recruits existing neurons to take over for those that are lost from stroke. It shows that in mice, undamaged neurons do not change their function after a stroke ...
