or functional status of the subject. Sensory processing In animal models of TBI, sensory processing has been widely studied to show systematic defects arise and are slowly but likely only partially recovered. It is especially characterised by an initial period of decreased activity in upper cortical layers. This period of decreased activity has also been characterised as by specific timing effects in the patterns of cortical activity in these upper layers in response to regular sensory stimuli.
