The axon initial segment (AIS) functions as both a physiological and physical bridge between somatodendritic and axonal domains. Given its unique molecular composition, location, and physiology, the AIS is thought to maintain neuronal polarity. To identify the molecular basis of this AIS property, we used adenovirus-mediated RNA interference to silence AIS protein expression in polarized neuron...

objective : executive functions refer to a group of higher-order cognitive processes responsible for self-regulated and targeted behaviors. this study aimed to investigate the effects of age and gender on executive functions focusing on three distinct areas of attentional control, planning and set-shifting among18-80 year-old healthy subjects. materials and methods: this cross-sectional study e...

Young infants show unexplained asymmetries in the exclusivity of categories formed on the basis of visually presented stimuli. They will also, on some occasions display retroactive interference when shown a succession of visual stimuli whereas on other occasions no interference is found. We describe a connectionist model that shows similar exclusivity asymmetries when categorising the same stim...

Ordered tetrad data yield information on chromatid interference, chiasma interference, and centromere locations. In this article, we show that the assumption of no chromatid interference imposes certain constraints on multilocus ordered tetrad probabilities. Assuming no chromatid interference, these constraints can be used to order markers under general chiasma processes. We also derive multilo...
