Kirste, I., Nicola, Z., Kronenberg, G., Walker, T. L., Liu, R. C., &Kempermann, G. (2015). Is silence golden? Effects of auditory stimuli and their absence on adult hippocampal neurogenesis.
We have previously hypothesized that the reason why physical activity increases precursor cell proliferation in adult neurogenesis is that movement serves as non-specific signal to evoke the alertness required to meet cognitive demands. Thereby a pool of immature neurons is generated that are potentially recruitable by subsequent cognitive stimuli. Along these lines, we here tested whether auditory stimuli might exert a similar non-specific effect on ...
