Dependence Of The Nociceptive Withdrawal Response On Stimulus Location In The Intact, Unanesthetized Rat, Brady Simpson
Dependence Of The Nociceptive Withdrawal Response On Stimulus Location In The Intact, Unanesthetized Rat, Brady Simpson
Senior Honors Projects, 2020-current
The nociceptive withdrawal response (NWR) is a critical movement characterized by the avoidance of noxious or otherwise unwanted stimuli. The response is mediated in mammals by withdrawal of the hind limb. Although the NWR has been studied in humans and spinalized animals, it is unclear whether there is a dependence on stimulus location in intact, unanesthetized, non-human animals. The specific aim of my research was to use high speed video of the intact, unanesthetized rat’s limb to determine if there was an effect of stimulus location on hind limb movement during the NWR evoked by heat stimuli. I hypothesized, based …

Investigating The Role Of Integrin Beta 3 In Dendritic Arborization In The Supragranular Developing Cerebral Cortex, Zachary Logan Holley

Integrin subunits have been implicated in axonal and dendritic outgrowth. In particular, a strong positive association has been found between mutations in integrin beta 3 (Itgb3) and autism spectrum disorder, but little is known about neuronal Itgb3 function in vivo. Many forms of autism spectrum disorder are thought to arise from dysfunctional dendritic arborization and synaptic pruning. Global knockout of Itgb3 in mice leads to autistic-like behaviors. Itgb3-/- mice also have reduced callosal volume, a key neuroanatomical correlate of autism. Here, we test the hypothesis that Itgb3 is required for normal dendritic arborization in layer II/III pyramidal …
