Abstract Connections between the insular cortex and the amygdala were investigated with tritiated amino acid autoradiography and horseradish peroxidase histochemistry in the rhesus monkey. Our findings revealed widespread reciprocal connections between the insular cortex and almost all subnuclei of the amygdaloid complex. The posterior insula projects predominantly to the dorsal aspect of the lateral and to the central amygdaloid nuclei. In contrast, the anterior insula projects to the anterior… Expand
Amygdaloid connections with posterior insular and temporal cortical areas in the rat
TLDR
The connections of the amygdala with the insular and temporal cortices were examined by injecting wheat germ agglutinin conjugated to HRP (WGA‐HRP) into the rat cortex and retrograde and anterograde labeling was observed in the contralateral amygdala. Expand
Frontal cortex projections to the amygdaloid central nucleus in the rabbit
TLDR
The present study describes the topography and origin of frontal cortex projections to the nucleus based upon retrograde and anterograde axonal transport techniques and suggests that the insular cortex possesses the potential to directly influence the central nucleus projection to cardiovascular/autonomic regulatory nuclei of the dorsal medulla and thus, together with the amygdaloid central nucleus, appears to be an important component of a forebrain system involved in cardiovascular/Autonomic regulation.

Circuitry and functional aspects of the insular lobe in primates including humans
TLDR
The progress made in understanding the insula in the decade following an earlier review is examined and confirmation has been given to theinsula as a visceral sensory area, visceral motor area, motor association area, vestibular area, and language area. Expand
Amygdala interconnections with the cingulate motor cortex in the rhesus monkey
TLDR
The prominent amygdala projection to the face region of M3 may significantly influence the outcome of higher‐order facial expressions associated with social communication and emotional constructs such as fear, anger, happiness, and sadness. Expand

TLDR
The amygdalofugal projections to the auditory cortices are more widespread and more complex than the Amygdalopetal projections of the auditory Cortical cortices. Expand
The amygdalostriatal projections in the monkey. An anterograde tracing study
TLDR
Amygdalostriatal projections have been studied in the monkey with the autoradiographic method for demonstrating axonal transport of tritiated amino acids and appear to arise mainly from the magnocellular part of the basal nucleus. Expand
Amygdala projections to central amygdaloid nucleus subdivisions and transition zones in the primate
TLDR
To examine how information flows through this key output region of the primate amygdala, small injections of retrograde tracers are placed into the subdivisions of the central nucleus in Old world primates, and inputs from specific amygdaloid nuclei are examined. Expand
Evidence for a direct projection from the superior temporal gyrus to the entorhinal cortex in the monkey
TLDR
Evidence is derived principally from experiments in which small volumes of wheat germ agglutinin-conjugated horseradish peroxidase (WGA-HRP) were injected into different parts of the entorhinal cortex, but has been confirmed by 3H-amino acid autoradiography. Expand

TLDR
There is anatomical evidence which suggests that there are important differences in the extent of convergence of cortical projections in the primate versus the nonprimate amygdala. Expand

Temporal neocortical afferent connections to the amygdala in the rhesus monkey
TLDR
The findings reveal that a far greater proportion of the temporal neocortex than previously described contributes afferents to the amygdala, further strengthening the view that the amygdala occupies a key anatomical position linking the neocortex with diencephalic structures. Expand
Cortical and subcortical afferents to the amygdala of the rhesus monkey (Macaca mulatta)
TLDR
The findings indicate that certain agranular or dysgranular cortical regions may project directly to the amygdala: in particular, the orbital frontal cortex, anterior cingulate gyrus, subcallosal gyrus), temporal pole and anterior insula. Expand
The efferent connections of the ventromedial nucleus of the hypothalamus of the rat ,
TLDR
The efferent connections of the ventromedial nucleus of the hypothalamus (VMH) of the rat have been examined using the autoradiographic method to identify labeled axons which follow a ventral amygdalopetal route from the lateral hypothalamic area and ventral supraoptic commissure. Expand

TLDR
Insular‐diencephalic connections have been studied in five rhesus Macaques with both retrograde and anterograde degeneration techniques and suggest that insular cortex is an extension of sensory‐motor cortex as indicated by physiologic data. Expand
Regional distribution of choline acetyltransferase and acetylcholinesterase within the amygdaloid complex and stria terminalis system
TLDR
Cholinergic neural elements in the amygdala are concentrated primarily in the basolateral complex and suggest that this region may be innervated by cholinergic fibers traveling in the ventral amygdalo-fugal pathway. Expand

It was concluded that the taste system has only sustaining projections to the neocortex, and that the other taste nerve projection areas located in somatic sensory area I were included in the lesion, complete degeneration of thalamic taste neurons resulted. Expand
