... (aside note: Recent evidence by Frisen group in Sweden (Spalding et al, 2013) found definitive evidence for DG neurogenesis in humans. By modelling the process of carbon 14 presence in brain cells, the team estimated that we generate around 1400 new neurons every day in the DG, roughly the same perc ...

It presumably requires internal (idiothetic) cues as to the direction and distance of movements. This might come from several sources including: vestibular input, prop ...

... (Honig and Urcuoli, 1981). Responses to stimuli parametrically varied in similarity to an aversively conditioned stimulus (CS+) are compared and typically a gradient is observed, i.e. less fear response with more dissimilar stimuli. This process of pattern separation correlates with activity in the ...

... D’Aguanno et al. [1] obtained L=1.51 that was quite comparable with our results. The cable theory allows to estimate the neurite extension (ne) knowing the length constant (λ), by equation: ne = Lλ. The length constant is further related to the diameter of the neurite (d), the membrane resistance (R ...

Despite the fact that the exact mechanism by which sleep deprivation reduces neurogenesis in the adult hippocampus is unknown, there is strong evidence supporting glucocorticoid release, due to the stress of chronic s ...
