Bioelectrical activity of brain in Rana tigrina (Daudin) in response to phosalone poisoning.

An acute dose of phosalone, intraperitoneally injected to Rana tigrina alters the bioelectrical activity of the brain. The frequency levels of delta, theta, alpha, and beta waves remained similar in both control and experimental groups, while the amplitude of the waves was significantly decreased by 40 to 60% in the latter group. The total work done (TWD) was also significantly reduced.
