By processing inputs received from the cerebral motor cortex, various brain stem nuclei, and sensory receptors, the _____ provides the precise timing and appropriate patterns of skeletal muscle contraction for smooth, coordinated movements and agility needed for out daily living- driving, typing, and for some of us, playing the tuba. In five experiments, we examined the time course of hemispheric differences in solution activation for insight-like problems. We propose that solving insight problems requires retrieval of unusual interpretations of problem elements, and that right-hemisphere (RH) coarse semantic coding is more likely than left-hemisphere (LH) fine semantic coding to maintain semantic activation of such.

Recent data have shown that parallel processing by the cerebral hemispheres can expand the capacity of visual working memory for spatial locations (J. F. Delvenne, ) and attentional tracking (G. A. Alvarez & P. Cavanagh, ). Evidence that parallel processing by the cerebral hemispheres can.   The brain may address this trade‐off by employing multiple processing strategies, distributed across the two cerebral hemispheres. In particular, left hemisphere language processing seems to be oriented toward prediction and the use of top‐down cues, whereas right hemisphere comprehension is more bottom‐up, biased toward the veridical.

The attentional model of hemisphere differences proposed by Kinsbourne is reviewed, and some of the difficulties inherent in this model are pointed by: 9.

This study investigated the depth of associative activation in the cerebral hemispheres. Semantic priming was assessed for direct (WATER-DRINK) and indirect (mediated: SOAP-DRINK) associates.

Kinsbourne’s selective activation model was evaluated in a sample of 31 strongly right-dominant males. Priming manipulations were hypothesized to preferentially activate a hemisphere and to improve performance on an affect-recognition task in the contralateral visual field. Subvocal rehearsal of neutral words was the left-hemisphere manipulation, while subvocal rehearsal of affective words.

The cerebral hemispheres are well differentiated in the human brain; each receives information and controls the contralateral body part, called the hemifield.

That is, the right cerebral hemisphere controls the left hemifield and the left cerebral hemisphere controls the right hemifield. Although at first glance both hemispheres may seem the same, they actually have anatomical and functional.

the intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body's ultimate control and information-processing center. cerebral cortex cont. the cerebrum consists of an outer cerebral cortex, composed of 2 to 4 mm of gray matter and underlying white matter.

The vertebrate cerebrum is formed by two cerebral hemispheres that are separated by a groove, the longitudinal brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter, the cerebral cortex, that is supported by an inner layer of white eutherian (placental) mammals, the hemispheres.

The two cerebral hemispheres are divided in the midsagittal plane by the interhemispheric er they fill most of the intra-cranial cavity. Gross anatomy.

INTRODUCTION. Priming is related to the facilitating effects of antecedent events (primes) on subsequent performance (responses to targets). This relates to perfecting the capacity of detecting or identifying words, objects or figures after a recent experience with them.
