“…The relevance of a stimulus to the task at hand is a contributor to how the stimulus is processed, with more relevant stimuli eliciting more robust cortical responses. Previous work by our lab demonstrated that the somatosensory-evoked N70 potential is enhanced when the evoking stimulus is task-relevant and attenuated when the evoking stimulus is irrelevant during a sensory grading task (Adams et al, 2017 , 2019 ). When the ability to downregulate cortical excitability to irrelevant distractor stimuli was disrupted using cTBS applied to the prefrontal cortex, these distractors exerted a greater behavioral cost during the sensory grading task (Adams et al, 2019 ).…”

“…The present study was designed to investigate how a history of concussion affected the tactile-evoked N70 ERP, which we have shown to be a cortical correlate of task relevance and distractibility in two separate groups of participants (Adams et al, 2017 , 2019 ). The first hypothesis of the present experiment was that relevancy-based sensory gating would be impaired in participants with a history of concussion, resulting in less suppression of N70 cortical responses to task-irrelevant stimuli.…”

“…To improve the verification performance, we investigated the knowledge of the response to the vibration stimuli and found that the response to the vibration stimuli appeared within approximately 1 s immediately after the stimuli for a short time stimuli [3], [4]. Specifically, when a perceivable oscillatory stimulus was presented, positive to negative potential changes such as P50, N70, P100, and N140 appeared approximately 50 or 100 ms after the stimulus.…”

“…Further evidence comes from visual attention deficits in neuropsychiatric disorders known to involve dopamine alterations in the brain, such as Parkinson’s disease (Tommasi et al 2015 ; McCoy et al 2020 ) and schizophrenia (Braver et al 1999 ; Keedy et al 2009 ). Next to the neurotransmitter level, there is evidence in humans at the neuroanatomical level for a crucial role of the PFC and a modulating function of the striatum from neurostimulation studies (Adams et al 2019 ; Wang et al 2020 ), lesion studies (Voytek and Knight 2010 ; Wolf et al 2014 ), and functional MRI studies (Anderson et al 2007 ; Parhizi et al 2018 ; Wang et al 2020 ).…”
