TBI can result in long-lasting cognitive and motor deficits, particularly if they occur in young people. Our place in the world depends on our sensation of the world around us and our responsiveness to these sensations, thus we have hypothesized that a significant contributor to the cognitive and motor deficits seen after TBI could arise from changes in sensory processing. 

This talk will outline how we have used the exploratory and discriminative tactile system in rats, their macrovibrissae, which feeds to the barrel cortex of the somatosensory cortex, to better understand how TBI affects neuronal signalling in the various layers of the cortex over time. Additionally, we have modelled how these changes may appear when extra-cranial electrophysiology is used to provide the information needed to monitor and understand the changes in neuronal functionality in humans suffering from TBI.
