The Long-Term Teratogenic Effect of Prenatal Alcohol Exposure on the Somatosensory and Motor Cortex of Rats
… barrel subfield (PMBSF), representing mystacial vibrissae of the rodent. A second highly studied region of the barrel cortex is the forepaw barrel subfield (FBS), representing the forepaw.</p> <p>One hallmark feature of PAE is the behavioral disruptions seen in fine motor control. These deficits …

Effects of Whisker-Trimming on GABAA Receptors in S1 Cortex
… by sensory deprivation, rats had mystacial vibrissae in middle row C or rows ABDE trimmed for 6 weeks beginning in early adulthood. Layers 2/3 above the deprived and adjacent whisker barrels were located in tangential sections, using patterns of radial blood vessels as fiducial marks. In …

Causal evidence for the behavioral impact of oscillations in neocortex and hippocampus
… gamma enhances the detection of threshold-level vibrissae deflections, analogous to the behavioral effects of shifting attention. By triggering stimulation of fast-spiking interneurons in the hippocampus on peaks and troughs of endogenous rhythms, I can reduce spike activity at specific phases of …

Considerations for automated NDE applications
… Finally a new NDE sensor concept based on the vibrissae of rodents such as rats and mice, for both surface roughness and surface profiling measurement, was adapted and investigated for NDE sensing applications. The results document a contribution to knowledge in the area with discrimination …

Molecular-Genetic and Behavioral Analysis of the Functionality of Patterning in the Trigeminal Neuraxis
… and physiologically, to the pattern of vibrissae on the snout. The vibrissal system is required for several classes of behavior, including feeding and active vibrissal sensing, but the functional role of the patterning in these behaviors is unknown. We used two mutant animals lacking …

Some principles of somatosensory cortical organization in rats and humans
… peripheral field, spanning on average 2 vibrissae in each direction from the vibrissa that evoked the largest input (the primary vibrissa). Inputs across the subthreshold receptive field were not homogeneous, as the latency to onset, rise time and prevalence of inhibition varied as a …

Conservation ecology of the Cape clawless otter, Aonyx capensis, in an urban environment
… I collected spraint from living otters and vibrissae from dead otters to investigate their diet. I predicted that otters would show an increased reliance on marine foods in areas where freshwater habitats were degraded in addition to seasonal variation in diet associated with the marked …
