. 2003 Apr;
24(4):597-606.
PMID: 12714117
Physical activity appears to attenuate the decline of cognitive function typically observed in older men and women. The P300 component of the event-related potential (ERP) is particularly affected by aging...

. 2001 Nov;
58(3):263-77.
PMID: 11698117
A number of investigators have reported elevated left temporal alpha power in marksmen during response preparation. This finding has been interpreted to indicate the suppression of irrelevant cognitive processes. However,...
