Some regions in the mesencephalon, such as dorsal periaqueductal gray, inferior colliculus
and deep layers of superior colliculus have been grouped together as a continuos strip of …

A synthesis of cat auditory cortex (AC) organization is presented in which the extrinsic and
intrinsic connections interact to derive a unified profile of the auditory stream and use it to …

It has been shown that the gradual increase in the intensity of electrical stimulation of the
dorsal periaqueductal gray (DPAG), deep layers of the superior colliculus (DLSC) and …

A general statement of the function of the inferior colliculus is lacking, even after more than
three decades of electrophysiological investigation. A neuroethological theory is proposed …

The opioid system plays a crucial role in the neural modulation of anxiety. The involvement
of opioid ligands and receptors in physiological and dysfunctional forms of anxiety is …

The main goal of this article is to review the key role that the inferior colliculus plays in the
expression of acoustic-motor and acoustic-limbic integration involved, respectively, in acute …

The discovery of different GABA receptor subtypes has stimulated research relating this
neurotransmitter to a variety of behavioral functions and clinical disorders. The development …

The medial hypothalamus, amygdala, and dorsal periaqueductal gray constitute the main
neural substrates for the integration of aversive states in the brain. More recently, some …

The inferior colliculus (IC) is a well known relay station for auditory pathways in the
brainstem. In the present review we are suggesting that aversive states are also generated …

In midbrain tectum (MT) structures, such as the dorsal periaqueductal gray (dPAG), the
superior colliculus (SC) and the inferior colliculus (IC) GABAergic neurons exert a tonic …
