SUMMARY The relationship between the nature of auditory signals and the type of response made by two-day-old infants was investigated. Pure tones were not found to be effective stimuli, even when presented for a long duration. Pure tones which were i

The relative effectiveness of complex and simple auditory signals was examined by presenting 2-day-old infants with a sequence of stimuli consisting of a white noise and a variety of pure tones (which ranged from 250 to 8000 Hz). “Catch” trials d

Cyclic AMP functions as the chemotactic signal during aggregation of amoebae of the cellular slime mold Dictyostelium discoideum. Evidence suggests that cAMP also acts as a regulatory molecule during Dictyostelium multicellular differentiation. We ha

To determine the effects of androgen on penile mechanoreceptor activity and sensitivity, first-order afferent responses, evoked by quantified tactile stimulation of the penis, were measured in sexually experienced intact and castrated cats. The resul

Altering penile sensitivity of cat leads to mating behavior that is aberrant in several respects, among which is disoriented pelvic thrusting. To characterize the receptors involved in such sensitivity changes, recordings were made of single-unit act
