Intermanual transfer in the monkey as a function of amount of callosal sparing

摘要: Summary The effects of commissure section, task difficulty and overtraining on the intermanual transfer tactile learning have been examined. Twenty-one rhesus monkeys were allocated to 4 groups. One group was subjected complete transection corpus callosum, massa intermedia posterior commissure. Some this also sustained a cerebellar section. A second received similar division commissures but with part body callosum left intact. third fourth formed an unoperated control group. Animals only intact showed little or no transfer. partial callosal lesions significantly greater than animals total transections, impaired relative controls. Estimates made number fibres in lesions. These estimates correlated correlation significant one task. Neither nor found affect significantly. comparison submodalities size roughness inconclusive.
