Since the pioneering work of Penfield and his colleagues in the 1930s, the somatosensory
cortex, which is located on the postcentral gyrus, has been known for its central role in …

Time is a universal psychological dimension, but time perception has often been studied
and discussed in relative isolation. Increasingly, researchers are searching for unifying …

Out of all the human senses, touch is the one that is most often unappreciated, and
undervalued. Yet, the surface of the human body, the skin, is actually one huge sheet of …

Alzheimer's disease (AD) and antecedent factors associated with AD were explored using
amyloid imaging and unbiased measures of longitudinal atrophy in combination with …

Functional neuroimaging has proven highly valuable in mapping human sensory regions,
particularly visual areas in occipital cortex. Recent evidence suggests that human parietal …

We are not passive recipients of the information that impinges on our retinae, but active
participants in our own perceptual processes. Visual experience depends critically on …

Fronto-parietal activity has been frequently observed in fMRI and PET studies of attention,
working memory, and episodic memory retrieval. Several recent fMRI studies have also …

In monkeys, the somatosensory cortex on the parietal operculum can be differentiated into
several distinct cortical fields. Potential human homologues for these areas have already …

Braille reading depends on remarkable adaptations that connect the somatosensory system
to language. We hypothesized that the pattern of cortical activations in blind individuals …

Background In functional brain imaging studies, exposure to cues related to cocaine,
opiates, and alcohol in dependent individuals is associated with activation of the anterior …
