Callosal disconnection neglect: reassessment after 34 years.

In 1984, Watson and Heilman reported a patient with a partial callosal disconnection following an infarction of the anterior portion of her corpus callosum. This woman's performance on line-bisection tasks revealed "callosal disconnection neglect." The objective of this research is to reexamine this woman 34 years after her callosal disconnection to gain information about her recovery.
