Abstract
After the establishment of fluorosis animal model, the gene expression of SNAP-25 was detected in order to provide experimental data for nervous system injury induced by fluoride. The results showed that, compared with the de-ionized water group, SNAP-25 mRNA expression was significantly reduced by fluoride.

Effect of exercise on microglial activation and transcriptome of hippocampus in fluorosis mice.
Highlights Exercise alleviated fluoride-induced activation of microglia in hippocampus. Exercise altered the expressions of 670 genes in hippocampus of fluorosis mice. Neuroactive ligand-receptor interaction pathway involved in the regulation of exercise on neuro-fluorosis. Fluorosis is a widespread endemic disease. Reports have shown that high fluoride causes the dysfunction of central

Fluoride exposure during pregnancy and lactation triggers oxidative stress and molecular changes in hippocampus of offspring rats.
Highlights Fluoride exposure indirectly increased the levels of F in the offspring's plasma. Fluorine exposure promoted biochemical imbalance in the offspring's hippocampus. The 10 mgF/L and 50 mgF/L groups showed an overexpression of the neurotrophin BDNF. In exposed groups modulation of the proteomic profile of the offspring. Proteins associated

Molecular mechanism of brain impairment caused by drinking-acquired fluorosis and selenium intervention
This study investigated the molecular mechanism of brain impairment induced by drinking fluoridated water and selenium intervention. Results showed that the learning and memory of rats in NaF group significantly decreased. Moreover, the number of apoptotic cells, the expression levels of Cytc mRNA and protein, and the expression levels of

Evaluation of fluoride-induced oxidative stress in rat brain: a multigeneration study.
Multigenerational evaluation was made in rats on exposure to high fluoride (100 and 200 ppm) to assess neurotoxic potential of fluoride in discrete areas of the brain in terms of lipid peroxidation and the activity of antioxidant enzyme system. The rats were given fluoride through drinking water (100 and 200 ppm) and

Detrimental Effects of Sodium Fluoride on the Expression of Insulin Receptor in the Olfactory Bulb and Hippocampus of Male Mice.
Fluoride exposure is associated with lowered cognitive function ability, intelligence quotient, and mental decline, especially in children. The brain insulin receptor (IR) signaling system is related to neuronal plasticity and consequent cognitive ability. In our previous study, NaF exposure decreased IR expressions in olfactory bulb (OB) and hippocampus after Y-maze

Fluoride Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

Fluoride's Direct Effects on Brain: Animal Studies
The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.

Fluoride's Effect on Fetal Brain
The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts

Fluoride: Developmental Neurotoxicity.
Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching
