Document Summary
De beaumont et al. (2007) >> n2pc and p300 in non-concussed, 1 concussion and 2+ concussed football players. Found that p300 reaction time tests become impaired after one concussion (takes longer to classify stimuli) N2pc (responsible for visuospatial attention) is not affected as much (same across the 3 groups) Shows that neuropsychological batteries are not sensitive enough (i. e. mris) Munoz and everling (2004) >> studied the difference between prosaccade and antisaccade neuron activation in monkeys. Antisaccade movements took a longer time (280-300ms vs. 160-200ms for prosaccades) When the stimulus is presented, there are more saccade/motor neurons associated with prosaccades than antisaccades. Fewer fixation neurons are required for a movement to occur in prosaccades. When directing the monkey to produce an antisaccade, the monkey has to inhibit the response and more activity is involved in the inhibition response. Antisaccades involve more high motor cognitive control and more cortical pathways than the prosaccades.
