This study presents a method for analyzing and remediating the visual perceptual deficits often found in persons with acquired right brain injury due to stroke. A total of 57 patients were randomly assigned to experimental (N=25) or control (N=32) groups. All patients were administered the same test battery prior to assignment. Experimentals received the specific training program and the controls received standard rehabilitation. Both groups were retested after a period of one month. Analysis revealed the superior performance of the experimental group. The results suggest that the academic disorders found in right brain damage can be treated as secondary to a primary disturbance in visual scanning behavior.

The effects of purified scorpion toxin (Tityustoxin or TsTX) were investigated on the isolated guinea-pig and rat ileum, rat spleen strip and hen rectal caecum. The contraction of the ileum was due only in part to the release of acetylcholine, whereas the contraction of the spleen strip and the relaxation of the rectal caecum were due to the release of catecholamines.
