TLDR
In this paper, a series of epidural and intracortical locations following stimulation of the contralateral median nerve in the monkey have been identified as the sources of the average somatosensory evoked potentials (SEPs) and associated multiple unit activity (MUA).About:

Journal ArticleDOI
The underpinnings of the BOLD functional magnetic resonance imaging signal.
TL;DR: The good coverage and high resolution afforded by functional magnetic resonance imaging make it an excellent tool for the noninvasive imaging of the human brain and the use of this technique in animal studies using high magnetic fields is interesting.
Journal ArticleDOI
Neural correlates of consciousness: progress and problems
TL;DR: Recent findings showing that the anatomical neural correlates of consciousness are primarily localized to a posterior cortical hot zone that includes sensory areas, rather than to a fronto-parietal network involved in task monitoring and reporting are described.
Journal ArticleDOI
The neural basis of the blood-oxygen-level-dependent functional magnetic resonance imaging signal.
TL;DR: These findings, together with an analysis of the neural signals, indicate that the BOLD signal primarily measures the input and processing of neuronal information within a region and not the output signal transmitted to other brain regions.

Central somatosensory conduction in man: neural generators and interpeak latencies of the far-field components recorded from neck and right or left scalp and earlobes.

TL;DR: Early somatosensory evoked potential components to median nerve or finger stimulation were recorded with non-cephalic references in normal young adults to identify spinal entry time with the onset of the neck N11 or scalp P11 and suggest that FF3-FF4 are generated in medial lemniscus rather than above the thalamus.
Journal ArticleDOI
On the nature of the BOLD fMRI contrast mechanism
TL;DR: Current knowledge of the extracellularly measured signals of the neural processes that they represent and of the structural and functional neurovascular coupling, which links such processes with the hemodynamic changes that offer the surrogate signal that is used to map brain activity are discussed.

Posterior parietal association cortex of the monkey: command functions for operations within extrapersonal space
TL;DR: A large proportion of area 5 neurons were relatively insensitive to passive joint rotations, as compared with similar neurons of the postcentral gyrus, but were driven to high rates of discharge when the same joint was rotated during an active movement of the animal.

TL;DR: Under the conditions of skull and scalp boundaries and intracranial inhomogeneities, recordings from a single electrode position offer little indication as to the location of a wave's neural generator(s), whereas multiple recording sites may be more informative.

Intracortical connectivity of architectonic fields in the somatic sensory, motor and parietal cortex of monkeys
TL;DR: Anterograde and retrograde transport methods were used to study the corticocortical connectivity of areas 3a, 3b, 1, 2, 5, 4 and 6 of the monkey cerebral cortex, finding possible multiple representations of the body surface in the component fields of the first somatic sensory area (SI).

TL;DR: The study on the somatic sensory cortex of the cat to the monkey is extended not only for the obvious reason of its closer affinity to man, but also because the larger size and clearer boundaries of the architectonic and functional subdivisions of the first somatics sensory area make these individual subdivisions more amenable to investigation.
Journal ArticleDOI
Localization in somatic sensory and motor areas of human cerebral cortex as determined by direct recording of evoked potentials and electrical stimulation.
TL;DR: This study is unique in that cutaneous receptive fields related to specific cortical sites were defined by mechanical stimulation, as is done in animals, in contrast to electrical stimulation of peripheral nerves at fixed sites, as in scalp EP recordings.
