PET is used to demonstrate directly the specialization of function in the normal human visual cortex, and provides direct evidence to show that, just as in the macaque monkey, different areas of the human prestriate visual cortex are specialized for different attributes of vision. Expand
Area V5 of the human brain: evidence from a combined study using positron emission tomography and magnetic resonance imaging.
P positron emission tomography was used to determine the foci of relative cerebral blood flow increases produced when subjects viewed a moving checkerboard pattern, compared to viewing the same pattern when it was stationary. Expand
The neural correlates of maternal and romantic love
It is concluded that human attachment employs a push-pull mechanism that overcomes social distance by deactivating networks used for critical social assessment and negative emotions, while it bonds individuals through the involvement of the reward circuitry, explaining the power of love to motivate and exhilarate.

Neural correlates of beauty.
The results show that the perception of different categories of paintings are associated with distinct and specialized visual areas of the brain, that the orbito-frontal cortex is differentially engaged during the Perception of beautiful and ugly stimuli, regardless of the category of painting. Expand
The topographic organization of rhesus monkey prestriate cortex.
A distinct, topographically organized visual area, named V3A, was found in the region between areas V3 and V4 in the lunate and parieto‐occipital sulci, which supports the notion of a functional division of labour within the prestriate cortex. Expand
The neural basis of romantic love
The activity in the brains of 17 subjects who were deeply in love was scanned using fMRI, suggesting that a unique network of areas is responsible for evoking this affective state, and postulate that the principle of functional specialization in the cortex applies to affective states as well. Expand
The architecture of the colour centre in the human visual brain: new results and a review *
The authors' new insight into the organization of the colour centre in the human brain may also account for the variability in both severity and degree of recovery from lesions producing cerebral colour blindness (achromatopsia). Expand
A direct demonstration of perceptual asynchrony in vision
The results showed that subjects misbind the colour and the direction of motion because colour and motion are perceived separately and at different times, colour being perceived first. Expand
Functional organization of a visual area in the posterior bank of the superior temporal sulcus of the rhesus monkey

- 1 February 1974
The response of single neurones in this area to simple visual stimulation is reported and the cortex of the posterior bank of the superior temporal sulcus to receive a projection from visual cortical areas is shown. Expand
