Study Probes Corpus Callosum Connectivity & Visual Working Memory

DALLAS – August 11, 2016 – A paper published in the most recent edition of Psychophysiology explores how differing levels of corpus callosum connectivity among individuals can affect visual working memory.

In the paper, first author Eva Qin, a UT Dallas graduate student at the Center for Vital Longevity, hypothesized that because the two hemispheres of the brain separately process visual information, the degree of connectivity of the corpus callosum – a brain structure that supports interhemispheric communication – could have an effect on the way information is seen and remembered, in some case making conditions ripe for an illusion, or false memory.

Results indicated that less posterior connectivity in the corpus callosum may actually be a good thing, in terms of memory accuracy: Less means more in the sense that people with less connectivity seem to be less susceptible to blending the characteristics of objects into a false or hybrid memory, Qin said.

The research was conducted in the lab of Dr. Chandramallika Basak, and was supported by the Darrell K Royal Society.
