The areas of the brain that mediate knowledge about objects were investigated by
measuring changes in regional cerebral blood flow (rCBF) using positron emission …

The human brain localizes mental operations of the kind posited by cognitive theories.
These local computations are integrated in the performance of cognitive tasks such as …

Visual presentation of words activates extrastriate regions of the occipital lobes of the brain.
When analyzed by positron emission tomography (PET), certain areas in the left, medial …

Positron emission tomography (PET) was used to measure changes in regional cerebral
blood flow of normal subjects, while they were discriminating different attributes (shape …

Brain regions responsive to novelty, without awareness, were mapped in humans by
positron emission tomography. Participants performed a simple reaction-time task in which …

Positron emission tomography was used to measure changes in the regional cerebral blood
flow of normal people while they searched visual displays for targets defined by color, by …

It has been hypothesized that the brain organizes concepts into a mental map, allowing
conceptual relationships to be navigated in a manner similar to that of space. Grid cells use …

Although neurons in primary visual cortex are sensitive to the spatial distribution and
intensity of light, their responses have not been thought to correlate with the perception of …

In primates, neuronal representations of objects are processed hierarchically in
occipitotemporal cortices. A “novel” feature of objects is thought to emerge and become …

The functional architecture of the object vision pathway in the human brain was investigated
using functional magnetic resonance imaging to measure patterns of response in ventral …
