Two distinct representations of social vocalizations in the basolateral amygdala.

Acoustic communication signals carry information related to the types of social interactions by means of their "acoustic context," the sequencing and temporal emission pattern of vocalizations. Here we describe responses to natural vocal sequences in…

Responses in the inferior colliculus of the guinea pig to concurrent harmonic series and the effect of inactivation of descending controls.

One of the fundamental questions of auditory research is how sounds are segregated because, in natural environments, multiple sounds tend to occur at the same time. Concurrent sounds, such as two talkers, physically add together and arrive at the ear…

Pulmonary vasoconstriction in a canine model of neurogenic pulmonary edema.

The intracisternal administration of veratrine to the chloralose-anesthetized dog produces pulmonary hypertension (PH) and neurogenic pulmonary edema (NPE). To determine whether pulmonary vasoconstriction, mediated by a circulating agent, contributes…

Daily exercise and gender influence postexercise cardiac autonomic responses in hypertensive rats.
