Signal detection in the analysis of blood oxygen level-dependent (BOLD) functional magnetic
resonance imaging (fMRI) may be greatly hindered by cardiac pulsatility artifacts. Vessel …

It has recently been demonstrated that a cortical network of visuospatial and oculomotor
control areas is active for covert shifts of spatial attention (shifts of attention without eye …

To elucidate the neural basis of the recognition of tactile form and location, we used functional
MRI while subjects discriminated gratings delivered to the fingertip of either the right or left …

The insula serves as the primary gustatory and viscerosensory region in the mammalian
cortex. It receives visceral and gustatory afferent projections through dedicated brainstem and …

In the mammalian brain, the insula is the primary cortical substrate involved in the perception
of taste. Recent imaging studies in rodents have identified a “gustotopic” organization in …

Prevailing theories hold that the insula is functionally organized along its caudal-to-rostral
axis, with posterior regions coding lower-level sensory information and anterior regions …

Previous studies have shown that the conceptual representation of food involves brain regions
associated with taste perception. The specificity of this response, however, is unknown. …

Food advertisements often promote choices that are driven by inferences about the hedonic
pleasures of eating a particular food. Given the individual and public health consequences …

BACKGROUND Weight-loss diets often target dietary fat or carbohydrates, macronutrients
that are sensed via distinct gut-brain pathways and differentially affect peripheral hormones …

The homeostatic regulation of feeding behavior requires an organism to be able to integrate
information from its internal environment, including peripheral visceral signals about the …
