Abstract

Studies with animal models showed that cellular, structural, and behavioral changes induced by environmental enrichment are related to increased levels of brain-derived neurotrophic factor (BDNF) in the brain. These evidence suggest that BDNF could be an interesting biomarker of the effects of lifestyle on cognition and other behavioral parameters in humans, mainly if the BDNF alterations in brain are accompanied by correspondent peripheral modifications, since human studies depend basically on the evaluation of this neurotrophin in serum or plasma. To test this hypothesis, we analyzed the effects of environmental enrichment on long-term memory for object recognition and on BDNF levels of hippocampus, frontal cortex, and serum of rats exposed to an experimental protocol that could be more easily translated to human intervention studies. Animals were maintained for 10 weeks in a social (standard laboratory conditions) or enriched (increased opportunity for physical exercise and learning experiences) condition. In the 7th week, they were submitted to behavioral testing (open field and novel object memory task), and at the end of the 10th week, they were killed and BDNF levels were analyzed. Animals maintained in the enriched condition showed enhanced performance on the memory task in the absence of any significant alteration in central or peripheral BDNF levels. The results of this study are important to highlight the need to develop experimental protocols using animal models that more closely resemble the characteristics of studies with humans and motivate more investigations to determine the conditions under which BDNF could be a biomarker of the effects of environment enrichment.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Physical activity, cognitive stimulation, and a balanced diet can stimulate BDNF expression in humans and animals.

    “Several studies on both humans and animals show that physical activity, cognitive stimulation, and a balanced diet can stimulate BDNF expression [204–207].”

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.
