Summary
In cats with the lingual nerve and the preganglionic sympathetic nerve trunk dissected intravenous injection of caffeine enhanced the ability of the submaxillary gland to summate induction current stimull eliciting a secretory effect.
Summary
Specific dynamic action of food was studied in normal dogs and after extirpation of the cortex of one or both hemispheres of the brain. After complete decortication the curve of the spccific dynamic action of food slowly rises, then reaches the top and returns to the initial level after a much longer time than before the operation. These changes indicate that the cortex participates not only in conditioned but also in unconditioned reflex mechanism of specific dynamic action of food.
