Time of conscious intention to act in relation to onset of cerebral activity (readiness-potential). The unconscious initiation of a freely voluntary act.
The recordable cerebral activity (readiness-potential, RP) that precedes a freely voluntary, fully endogenous motor act was directly compared with the reportable time (W) for appearance of theExpand

Time of conscious intention to act in relation to onset of cerebral activity (readiness-potential). The unconscious initiation of a freely voluntary act.
SUMMARY The recordable cerebral activity (readiness-potential, RP) that precedes a freely voluntary, fully endogenous motor act was directly compared with the reportable time (W) for appearance ofExpand

Readiness-potentials preceding unrestricted 'spontaneous' vs. pre-planned voluntary acts.
The nature of readiness-potentials (RPs) that may be associated with fully endogenous, 'freely' voluntary acts was investigated. Restriction on when to act were eliminated and instructions fosteredExpand

Subjective Referral of the Timing for a Conscious Sensory Experience
PREVIOUS studies had indicated that there is a substantial delay, up to about 0.5 s, before activity at cerebral levels achieves ‘neuronal adequacy’ for eliciting a conscious somatosensory experienceExpand

Responses of human somatosensory cortex to stimuli below threshold for conscious sensation.
Averaged evoked responses of somatosensory cortex, recorded subdurally, appeared with stimuli (skin, ventral posterolateral nucleus, cortex) which were subthreshold for sensation. Such responses wereExpand

Relation of human electromyogram to muscular tension.
Abstract 1. 1. The integrated electromyogram parallels tension in human muscle contracting isometrically. 2. 2. No quantitative relation between EMG and tension exists when a muscle is allowed toExpand

Responses of Human Somatosensory Cortex to Stimuli below Threshold for Conscious Sensation
Averaged evoked responses of somatosensory cortex, recorded subdurally, appeared with stimuli (skin, ventral posterolateral nucleus, cortex) which were subthreshold for sensation. Such responses wereExpand

Subjective referral of the timing for a conscious sensory experience: a functional role for the somatosensory specific projection system in man.
Subjective experience of a peripherally-induced sensation is found to appear without the substantial delay found for the experience of a cortically-induced sensation. To explain this finding, inExpand

Preparation- or intention-to-act, in relation to pre-event potentials recorded at the vertex ☆
A slow negative shift in potential, recordable extracranially, appears during the second or so preceding a signal to which a subject is supposed to respond. The ’ contingent negative variation’ (CNV)Expand
