Gustatory cortex of primates: anatomy and physiology
TLDR
Clinical and physiological studies of patients with ageusia or gustatory hallucination suggest that the primary gustatory area (area G) lies at the anterior insula or at the base of the central sulcus, but physiological and anatomical studies in subhuman primates locate area G at the buried frontal operculum (Fop) and dorsal insula.About:

New insights into symptoms and neurocircuit function of anorexia nervosa
TL;DR: New brain imaging technology provides insights into ventral and dorsal neural circuit dysfunction — perhaps related to altered serotonin and dopamine metabolism — that contributes to the puzzling symptoms found in people with eating disorders.
Journal ArticleDOI
Three systems of insular functional connectivity identified with cluster analysis.
TL;DR: It is found that dorsal and ventral anterior insula responded selectively to disgusting images, while posterior insula did not, and clustering of connectivity patterns can be used to subdivide cerebral cortex into anatomically and functionally meaningful subregions.

TL;DR: Overall significantly more peaks originated from the right hemisphere suggesting asymmetrical cortical representation of taste favoring theright hemisphere.

Sucrose activates human taste pathways differently from artificial sweetener

TL;DR: Brain response distinguishes the caloric from the non-caloric sweetener, although the conscious mind could not, which could have important implications on how effective artificial sweeteners are in their ability to substitute sugar intake.

Flavor is in the brain
TL;DR: It is proposed that taste, oral-somatosensory and olfactory inputs are first integrated in the anterior ventral insula, and then conveyed to upstream regions in the brainstem and thalamus, as well as downstream areas in the amygdala, orbitofrontal cortex and anterior cingulate cortex to produce the rich flavorful experiences that guide the authors' feeding behavior.

Changes in the visual system of monocularly sutured or enucleated cats demonstrable with cytochrome oxidase histochemistry
TL;DR: The results indicated that the deprivation caused by monocular suture produced a decrease in the cytochrome oxidase staining of the binocular segment of the deprived geniculate laminae of kittens, leading to a significant decreases in the level of oxidative enzyme activity one to several synapses away.

The Orbitofrontal Cortex: Neuronal Activity in the Behaving Monkey
TL;DR: Neurons in the orbitofrontal cortex of the alert rhesus monkey possess highly coded information about which stimuli are present, as well as information about the consequences of the animal's own responses, which may constitute a neuronal mechanism for determining whether particular visual stimuli continue to be associated with reinforcement, aswell as providing for the modification of theAnimal's behavioural responses to such stimuli when those responses are no longer appropriate.

Insula of the old world monkey. I. Architectonics in the insulo-orbito-temporal component of the paralimbic brain.
TL;DR: Observations of the insula of the rhesus monkey indicate that AChE histochemistry can be used for the architectonic analysis of cortex.
