Abstract
The present study investigates the effect of the Sodium Fluoride (NaF) on Wistar Albino mice. The animals have been divided into three batches each containing five individuals among which 1 batch served as control while, remaining two batches were treated with 5 and 10ppm respectively. After completion of exposure, the animals were subjected to behavioural studies. Then the animals were sacrificed and the brain regions were used for the biochemical analysis. Significant behavioral changes were observed in the NaF treated animals when compared to the control animals. Among the two doses the animals exposed to high dose showed significant changes compared to low dose exposed animals. Among the biochemical parameters studied AChE activity was decreased in the brain region of the animals exposed to NaF compared to the control. Besides decrease in AChE activity, ACh content was found to be increased in the brain regions of the NaF exposed animals. Among the different brain regions studied Cerebral Cortex was found to be more vulnerable to the NaF toxicity. However 10pm NaF showed more inhibition both in terms of behavioral and biochemical alterations in the Mice compared to the 5ppm exposed animals.

Calcium preventing locomotor behavioral and dental toxicities of fluoride by decreasing serum fluoride level in rats
Spontaneous motor activity, rota-rod performance (motor co-ordination), body weight gain, food intake, activities of total cholinesterase (blood) and acetylcholinesterase (brain), and dental structure were determined in adult female rats treated with a very high dose of sodium fluoride (500 ppm in drinking water) alone and in combination with calcium carbonate

Neuroprotective influence of taurine on fluoride-induced biochemical and behavioral deficits in rats
Epidemiological and experimental studies have demonstrated that excessive exposure to fluoride induced neurodevelopmental toxicity both in humans and animals. Taurine is a free intracellular B-amino acid with antioxidant and neuroprotective properties. The present study investigated the neuroprotective mechanism of taurine by evaluating the biochemical and behavioral characteristics in rats exposed

Interplay of ROS and behavioral pattern in fluoride exposed Drosophila melanogaster.
Highlights NaF exposure increases mortality and changes male-female ratio in Drosophila. NaF treatment alters the activities endogenous antioxidant enzymes. Chronic sub-lethal NaF exposure causes increased oxidative damage. NaF decreases brain cell viability and increases DNA damage. NaF exposure alters selected behavioral pattern in Drosophila melanogaster. Reactive oxygen species (ROS) is

Effects of sodium fluoride on locomotor behavior and a few biochemical parameters in rats
Spontaneous motor activity and motor coordination were tested in adult female rats after treating with sodium fluoride at 20 or 40 mg/kg dose level daily for 60 days, using an activity chamber and a rota-rod apparatus, respectively. Total protein concentrations were determined in skeletal muscle, liver and serum of similarly

Effect of fluoride exposure on anxiety- and depression-like behavior in mouse.
Highlights Anxiety-like behavior was significantly altered in the mice exposed to NaF for 120 days. Depression-like behavior was significantly altered in the 120 days NaF treated mice. NaF significantly altered mRNA expression levels of anxiety- and depression-like related genes in the hippocampus. Fluoride led to an imbalance between excitation and

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 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: 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

Fluoride & IQ: 67 Studies
As of May 2020, a total of 75 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 67 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal studies have found that fluoride exposure impairs the learning and/or
