Optogenetic spreading depression elicits trigeminal pain and anxiety behavior.
Authors
Abstract
Cortical spreading depression (SD) is an intense depolarization underlying migraine aura. Despite the weight of evidence linking SD to the pain phase of migraine, controversy remains over a causal role of SD in cephalgia because of the invasive nature of previous SD induction methods. To overcome this problem, we employed a novel minimally invasive optogenetic SD induction method and examined the effect SD on behavior.
