Traumatic brain injury can affect long-term sensory processing, which contributes to the ability of the injury to affect a person's functioning. After a TBI, sensory processing is often altered, but further research needs to be conducted on the nature of these alterations.
To explore this subject, Alwis, Yan, Morganti-Kossman, and Rajan used the rat whisker tactile system and the cortex processing whisker-derived input. Their experiment enabled them to examine changes in the neuronal responses in the columnar network in the primary sensory cortex of a rat's brain long-term.
The results suggest that TBI prompts long-term changes in the sensory parts of the brain and that the effects are dependent on the complexity of the sensory information. This research informs the types of sensory processes that may be affected by TBI.
