| Popis: | Whole body vibration (WBV) is a form of physical stimulation brought about by mechanical vibrations transmitted to a subject. WBV can increase attention in cognitive tasks in mice and men. However, little is known about the mechanisms that underlie this improved brain functioning. We examined whether WBV affects the cholinergic forebrain system of mice. Male C57Bl/6J mice (2 months of age) received WBV in a cage attached to a small vibrating platform (30 Hz with peak-to-peak displacements ranging from 14 to 75mm). WBV was applied five days a week for a period of five weeks with daily sessions of ten minutes. Control mice (pseudo-WBV) were treated similarly, but did not receive the actual vibration. Mice were sacrificed 24 hours after the last session and their brains were processed immuno cyto chemically for the acetylcholine-synthesizing enzyme cholineacetyl transferase (ChAT). ChAT-immunoreactivity was measured in the nucleus basalis magnocellularis (NBM), the somatosensory cortex, and the basolateral amygdala (where the cholinergic fibers arising from the NBM terminate). ChAT-immunoreactivity was significantly increased due to WBV in layer 5 of the somatosensory cortex (by 23%; p< 0.01) and amygdala (by 21%; p |
