Joshua A BurkJosh Burk is a Professor and Chair of the to Department of Psychological Sciences at the College of William and Mary. His is a neuropsychopharmacologist who studies neural mechanisms involved in attention and impulsivity. He and Dr. Fadel have a longstanding collaboration, which has been supported by two R01 grants. They have shown that blockade of orexin receptors, systemically or by infusion into the basal forebrain disrupts attentional performance (Boschen, Fadel, & Burk, 2009). They discussed the implications of these findings within the existing literature in a review paper (Fadel & Burk, 2010). Most recently, they showed that administration of orexin A can attenuate attentional deficits after a distracter or following loss of basal forebrain corticopetal cholinergic neurons (Zajo, Fadel, & Burk, 2016). They have a number of ongoing studies to understand the role of orexins/hypocretins in cognition associated with their current R01 grant. Read More Read Less
