Sleep deprivation causes many adverse effects on work performance. Many experiments in both human and rodent models reveal detriments that sleep deprivation has on learning and memory, including performance in a water radial arm maze (WRAM) task. This study utilizes the modified multiple platform method (MMPM) of sleep deprivation; rats were sleep deprived in order to study memory errors they may make during the WRAM task. The findings indicate that 6 hours of sleep deprivation for 2 five-day week periods did not affect performance in the WRAM task except on the initial day compared to the large platform group. The …

Dogs admitted to animal shelters experience psychological stressors resulting in elevated plasma cortisol. We previously found 30 min of human interaction reduced this response. The present study further characterized this effect, with the aim of developing a practical means of reducing stress of shelter dogs. We found that a second day of 30 min of petting reduced cortisol levels as effectively as the first. Further, 15 min of this interaction was as effective as 30 min. During petting, signs of excitation (vocalizations) and anxiety (panting) as well as escaped attempts were reduced, and social solicitation (tail-wagging) increased. However, cortisol levels …

Transcranial Direct Current Stimulation (tDCS) has been used to treat various mental and neurological illnesses. Rodent models have been used to examine physiological changes in the brain after tDCS, as well as to develop safety standards. However, most animal tDCS studies implant an electrode on the brain, potentially altering the path of current during stimulation. Additionally, no studies have been completed specifically examining maximum safe anodal tDCS limits, and a pilot study conducted to determine an electrode montage to examine biological changes of learning and memory from anodal tDCS indicated brain lesion was occurring before a commonly cited lesion threshold …

Peripheral nerve injury is known to induce several changes in the physiology and morphology of the injured afferent. These changes include hyperexcitability, decreased dorsal root potentials (DRP), loss of synaptic vesicles as well as loss of the vesicular glutamate transporter, VGLUT1. While many of the changes caused by peripheral injury revert with regeneration, others appear to be permanent. The loss of the stretch reflex for example is a puzzling outcome of recovery after peripheral nerve transection and regeneration, especially given that the electrical counterpart of the stretch reflex (the H-reflex) recovers after regeneration. We hypothesized that stretch induced transmission is …
