Abstract
Injection of the cerebrospinal fluid (CSF) collected from rats fatigue d by obligatory swimming into the cisterna magna of mice suppressed th e spontaneous motor activity of the mice. The suppressive activity was abolished by heat denaturation of the CSF and was found in the CSF fr action with a molecular weight above 10,000 after ultrafiltration. The se findings suggest the presence of a substance(s) released in a fatig ued animal's brain that suppresses its spontaneous motor activity and generates the sensation of fatigue, (C) 1998 Elsevier Science Inc.
