Learning deficit in BDNF mutant mice.

Linnarsson, Sten, Björklund, Anders, Ernfors, Patrik·1997·European Journal of Neuroscience

Abstract

Brain-derived neurotrophic factor (BDNF) has been implicated in the regulation of high-frequency synaptic transmission and long-term potentiation in the hippocampus, processes that are also thought to be involved in the learning of spatial tasks such as the Morris water maze. In order to determine whether BDNF is required for normal spatial learning, mice carrying a deletion in one copy of the BDNF gene were subjected to the Morris water maze task. Young adult BDNF mutant mice were significantly impaired compared with wild-type mice, requiring twice the number of days to reach full performance. Aged wild-type mice performed significantly worse than young wild-type mice and the effect was even more pronounced in the BDNF mutant mice, which did not learn at all. Although there was no difference in mean swimming speed between BDNF mutant and wild-type mice, we cannot exclude the possibility that developmental or peripheral deficits also contribute to the learning deficits in these mice. In situ hybridization and RNase protection analysis revealed that BDNF mRNA expression was indeed decreased in BDNF mutant mice. Furthermore, a pronounced effect of age on BDNF mRNA expression was seen, displayed as both a reduced level of mRNA expression and a reduced or entirely absent layer-specific expression pattern in the cerebral cortex of aged animals. Thus, our data suggest that BDNF expression may be linked to learning.

  • Manipulation of brain-derived neurotrophic factor expression directly impacts upon performance in spatial and contextual memory tasks.

    “The importance of BDNF to hippocampal neuroplasticity is epitomized by animal studies, which have found that the manipulation of BDNF expression directly impacts upon performance in spatial and contextual memory tasks (Linnarsson et al., 1997; Alonso et al., 2002; Heldt et al., 2007; Peters et al., 2010), and also that the downregulation of BDNF inhibits AE induced improvements in spatial memory”

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.
