Abstract

Repetitive transcranial magnetic stimulation (rTMS) is increasingly used as a therapeutic tool in various neurological and psychiatric disorders, and we recently found that it has a neuroprotective effect both in vitro and in vivo. However, the neurochemical mechanisms underlying the therapeutic effects are still unknown. We investigated the effects of long-term rTMS on the expression of brain-derived neurotrophic factor (BDNF), cholecystokinin (CCK), and neuropeptide tyrosine (NPY) mRNA in rat brain. In situ hybridization revealed a significant increase in BDNF mRNA in the hippocampal areas CA3 and CA3c, the granule cell layer, as well as in the parietal and the piriform cortex after rTMS. BDNF-like immunoreactivity was markedly increased in the same areas. A significant increase in CCK mRNA was observed in all brain regions examined. NPY mRNA expression, in contrast, was not altered. The present results suggest that BDNF may contribute to the neuroprotective effects of rTMS. Furthermore, the rTMS-induced changes in BDNF and CCK expression are similar to those reported after antidepressant drug treatment and electroconvulsive seizures, suggesting that a common molecular mechanism may underlie different antidepressant treatment strategies.

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.
