Rats, subjected to low-dose irradiation that suppressed hippocampal neurogenesis, or a sham treatment, were administered a visual discrimination task under conditions of high, or low interference. Half of the rats engaged in running activity and the other half did not. In the non-runners, there was no effect of irradiation on learning, or remembering the(More)
Adult neurogenesis in the hippocampal dentate gyrus plays an important role in learning and memory. However, the precise contribution of the new neurons to hippocampal function remains controversial. Emerging evidence suggests that neurogenesis is important for pattern separation and for mitigating interference when similar items must be learned at(More)
Cholinergic neurotransmission has been shown to play an important role in modulating attentional processing of visual stimuli. However, it is not yet clear whether the neurochemical acetylcholine (ACh) is necessary exclusively for visual attention, or if it also contributes to attentional functions through some modality-independent (supramodal) mechanism.(More)
the use of SDF-1 and SCF provides promise in enhancing regeneration in aged neural stem cells. Dr. Masashi Fujitani, a postdoctoral fellow in Dr. F. D. Miller’s laboratory at the Department of Physiology, shared his recent findings in a presentation titled “TAp73 regulates the self-renewal and maintenance of CNS neural stem cells.” Dr. Fujitani researches(More)
