Open field behavior after chronic self stimulation.
Long term exposure of adult male Sprague Dawley rats to rewarding brain stimulation produced alterations in open field behavior in comparison to nonstimulated controls. Initial activity was increased while movement latency was decreased for the experimental animals. Grooming and defecation were essentially unchanged by stimulation. These findings suggest a selective and tonic influence of brain stimulation upon exploration.
