Abstract

Increasing evidence suggests that regular exercise improves brain health and promotes synaptic plasticity and hippocampal neurogenesis. Exercise improves learning, but specific mechanisms of information processing influenced by physical activity are unknown. Here, we report that voluntary running enhanced the ability of adult (3 months old) male C57BL/6 mice to discriminate between the locations of two adjacent identical stimuli. Improved spatial pattern separation in adult runners was tightly correlated with increased neurogenesis. In contrast, very aged (22 months old) mice had impaired spatial discrimination and low basal cell genesis that was refractory to running. These findings suggest that the addition of newly born neurons may bolster dentate gyrus-mediated encoding of fine spatial distinctions.

  • Running induces an increase of performance in different hippocampus-dependent cognitive tasks, such as spatial memory and spatial pattern separation, novel object recognition, and contextual fear conditioning.

    “As for running, there is straightforward evidence that, in parallel with the surge of proliferation of progenitor cells, it induces an increase of performance in different hippocampus-dependent cognitive tasks, such as spatial memory and spatial pattern separation (Voss et al., 2013;Creer et al., 2010), or novel object recognition (Bolz et al., 2015) and contextual fear conditioning (Kohman et al.”
  • Improved spatial pattern separation in 3-month-old mice was tightly correlated with increased neurogenesis and vasculature in the dentate gyrus after 10 weeks of voluntary wheel running.

    “Another study found that improved spatial pattern separation in 3-month-old mice was tightly correlated with increased neurogenesis and vasculature in the dentate gryus after 10 weeks of voluntary wheel running (117).”

    From Lack of Exercise Is a Major Cause of Chronic Diseases (2012) · cites this paper as [117]

  • The blocking of aerobic exercise-induced improvements by inhibiting cell proliferation occurred only in conditions in which the task required fine spatial discriminations.

    “For example, inhibiting the rate of cell proliferation in mice was sufficient to impair pattern separation (Deng et al., 2010) and block AE-induced improvements in spatial (Clark et al., 2009) and contextual (Wojtowicz et al., 2008) memory performance, but only in conditions in which the task required fine spatial discriminations (i.e., where pattern separation was necessary; Creer et al., 2010).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
