Measuring latency distribution of transcallosal fibers using transcranial magnetic stimulation.

ABSTRACT:

Background

Neuroimaging technology is being developed to enable non-invasive mapping of the latency distribution of cortical projection pathways in white matter, and correlative clinical neurophysiological techniques would be valuable for mutual verification. Interhemispheric interaction through the corpus callosum can be measured with interhemispheric facilitation and inhibition using transcranial magnetic stimulation.

Objective

To develop a method for determining the latency distribution of the transcallosal fibers with transcranial magnetic stimulation.

Methods

We measured the precise time courses of interhemispheric facilitation and inhibition with a conditioning-test paired-pulse magnetic stimulation paradigm. The conditioning stimulus was applied to the right pr
