The manifested dominance split-brain monkeys usually show for performing visual tasks through one hemisphere, when perceptual information is equally available to both, was analyzed. Three split-brain monkeys, each being trained similar yet different discriminations to each hemisphere, were allowed the opportunity to choose between the two problems when both were presented simultaneously. Initia...
JOHNSON, J. D. AND M. S. GAZZANIGA. Reversal behavior in split-brain monkeys. PHYSIOL. BEHAV. 6 (6) 707--709, 1971.Using split-brain monkeys, reversal behavior was observed under two conditions. In the first both hemispheres viewed the discrimination cues. Previous to this one hemisphere had been taught to respond to one cue and the other hemisphere had learned the opposite response. The task w...
Two split-brain patients who differ in their right hemisphere language capacity were tested on a variety of simple cognitive tasks. Both isolated right hemispheres performed poorly on most tests. The results suggest that the presence of language in the right hemisphere, a brain system that ordinarily does not possess such competence, need not necessarily confer the full complement of cognitive ...
BACKGROUND AND PURPOSE Locomotor adaptation is a form of short-term learning that enables gait modifications and reduces movement errors when the environment changes. This adaptation is critical for community ambulation for example, when walking on different surfaces. While many individuals with traumatic brain injury (TBI) recover basic ambulation, less is known about recovery of more complex ...
The effects of emotionality and length on lateralized lexical decision of abstract nouns were investigated in 41 normal and three commissurotomized subjects. Emotionality had the same effect in both visual fields: Emotional words were responded to more accurately than neutral words. Length had different effects in the two visual fields: The accuracy of lexical decisions in the left visual field...
We used the Fsp technique to quantify the influence of changing stages of consciousness on the signal-to-noise ratio of the middle latency response (MLR). The MLR and polysomnographic activity were obtained from 10 subjects during a continuous 6-hour period. The Fsp statistic was applied to the MLR data in order to determine the number of scores above a specified criterion in each stage of cons...
