The surgical disconnection of the cerebral hemispheres creates an extraordinary opportunity
to study basic neurological mechanisms: the organization of the sensory and motors …

In the absence of the corpus callosum due to either surgical transection or congenital
agenesis, the interhemispheric exchange of information is disrupted, as emphasized by …

In recent years, a strong functional relationship between finger counting and number
processing has been suggested. Developmental studies have shown specific effects of the …

In order to study the role of the corpus callosum in two-handed coordination we tested
callosotomy subjects while they attempted to initiate simultaneous discrete movements with …

The split-brain phenomenon is caused by the surgical severing of the corpus callosum, the
main route of communication between the cerebral hemispheres. The classical view of this …

Malcolm Jeeves was the first to demonstrate lengthened interhemispheric transmission
times in subjects with agenesis of the corpus callosum by using a simple reaction time …

One subject with full forebrain commissurotomy (LB), two with callosotomy (JW and ME), one
with callosal agenesis (RB) and 10 normal subjects performed a simple reaction time task in …

Interhemispheric inhibitory interactions (IHI) operate between homologous distal hand
representations in primary motor cortex (M1). It is not known whether proximal arm …

A Fitts' task was used to examine whether the large movement asymmetry in subjects with
spastic hemiparesis can be reduced or eliminated when both limbs are required to perform …

Several structural imaging studies have revealed atrophy in regions of the corpus callosum
due to normal aging. We examined the performance of young and senior adults on 2 …
