Transcranial magnetic stimulation and cognitive neuroscience
The most important (and least understood) considerations regarding the use of transcranial magnetic stimulation for cognitive neuroscience are discussed and advances in theUse of this technique for the replication and extension of findings from neuropsychology are outlined.
The ganglion cell and cone distributions in the monkey's retina: Implications for central magnification factors
Post-decision wagering objectively measures awareness
It is shown that participants fail to maximize cash earnings by wagering high following correct decisions in blindsight, the Iowa gambling task and an artificial grammar task, demonstrating, without the uncertainties associated with the conventional subjective measures of awareness, that the participants were not aware that their decisions were correct.
Quantitative distribution of GABA-immunopositive and -immunonegative neurons and synapses in the monkey striate cortex (area 17).
The number of GABA-immunoreactive [GABA(+)] neurons and synapses was determined in functionally distinct subregions delineated as rich and poor in cytochrome oxidase (CO) in the visual cortex of adult macaque monkeys to determine the site of GABA influences in cortex.

The blindsight saga

The substantial literature on the effects of removing parts or all of V1 in monkeys on the residual physiological cerebral responses to visual stimuli in their field defects is at last directly relevant to human blindsight.
Striate cortex (V1) activity gates awareness of motion
From the timing and pattern of effects, it is inferred that back-projections from extrastriate cortex influence information content in V1, but it is V1 that determines whether that information reaches awareness.
The axo-axonic interneuron in the cerebral cortex of the rat, cat and monkey
Spatial neglect in near and far space investigated by repetitive transcranial magnetic stimulation.
The results reproduced in normal subjects the dissociation between neglect in near and far space that has been described in patients with different right-hemisphere lesions, and supports the contention that there is a dorsal/near space-ventral/far space segregation of processing in the visual system which reflects the behavioural goals of the two putative visual streams.

This Bartlett lecture narrates the discovery of blindsight and its mounting opposition, and it evaluates the continuing and often perplexing debate about its standing as a visual cognitive phenomenon.
