Rats receiving an IP injection ~f neuronal RNA from donors trained on a wire climbing ~ask performed significantly better over a three day learning period than did naive RNA or reagent blank controls. There were no significant differences between the naive RNA and reageJlt blank groups.

The applicability of a simple light-dark discrimination task to the study of RNA induced behavioral effects was investigated. Significant results with RNA extracted from trained donors using the cold phenol method support the value of this task in future RNA im'estigations.

An experiment was conducted to study the effect of strychnine sulfate on the exploratory behavior of male, Wistar rats in an open field. The number of times S reared in a stimulus square and the number of stimuli to which a S reared were recorded for both experimental and control Ss. Analyses of covariance performed on both measures of exploratory behavior showed that exploratory behavior was significantly increased by strychnine sulfate.
