Abstract

Age‐related memory loss is considered to commence at middle‐age and coincides with reduced adult hippocampal neurogenesis and neurotrophin levels. Consistent physical activity at midlife may preserve brain‐derived neurotrophic factor (BDNF) levels, new cell genesis, and learning. In the present study, 9‐month‐old female C57Bl/6J mice were housed with or without a running wheel and injected with bromodeoxyuridine (BrdU) to label newborn cells. Morris water maze learning, open field activity and rotarod behavior were tested 1 and 6 months after exercise onset. Here we show that long‐term running improved retention of spatial memory and modestly enhanced rotarod performance at 15 months of age. Both hippocampal neurogenesis and mature BDNF peptide levels were elevated after long‐term running. Thus, regular exercise from the onset and during middle‐age may maintain brain function. © 2011 Wiley Periodicals, Inc. Develop Neurobiol 72: 943–952, 2012

  • Physical exercise is able to overcome the age-dependent decline of hippocampal neurogenesis.

    “In contrast, physical exercise is able to overcome the age-dependent decline of hippocampal neurogenesis; running is indeed effective in 9-20 month-old rodents in restoring neurogenesis of at least 50% of the control level of young animals, and also the morphology of young neurons and BDNF levels, as well as spatial memory (Morris water maze and place recognition tests; van Praag et al., 2005;Siet”

    The Discussion reports that running increased hippocampal neurogenesis in middle-aged female mice and says age-related decline can be reversed “to some extent.” The Introduction adds that exercise did not restore neurogenesis to the level of younger animals, so “overcome” overstates the degree of reversal.

  • Animal models have shown aerobic exercise to be associated with a region-specific up-regulation of brain-derived neurotrophic factor in the hippocampus.

    “Animal models have shown AE to be associated with a region-specific up-regulation of BDNF in the hippocampus (Neeper et al., 1995; Marlatt et al., 2012; Uysal et al., 2015).”
  • Studies in animal models report an increase in brain BDNF levels when aged animals are submitted to protocols such as long-term environmental enrichment or physical activity.

    “Studies in animal models report an increase in brain BDNF levels when aged animals are submitted to protocols such as long-term environmental enrichment [47–49] or physical activity [50, 51].”

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.
