  • Abstract
  • Look Inside

A study was made of the arousal reaction and evoked muscular discharge in rabbits in an effort to clarify the functional mechanism of Pyrithioxn on the central nervous system. The results obtained are as follows ;

1. The thresholds of arousal reaction in the cerebral cortex and hippocampus as well as that of evoked muscular discharge in the fore and hind limsb due to stimulation of the reticular formation were decreased following intravenous or oral admi-nistration of Pyrithioxin.

2. Pyrithioxin showed a facilitatory effect on the evoked muscular discharge in the fore and hind limbs due to stimulation of the ceredral cortex. It showed a facilitatory effect at a small dose and an inhibitory effect at a large dose on the discharge due to stimulation of the hippocampus.

Thus, it was strongly suggested that Pyrithioxin might facilitate consciousness and pyramidal move-ment.
