Abstract
Rats receiving fluoride during the whole pregnancy up to the 9th day of lactation showed, when isolated at 10th day of life, a reduced rate of ultrasonic vocalizations (UV) in male pups (NaF 5.0 mg) and, in 90th days male rats, an increase of the Pre-Pulse Inhibition (PPI) with a reduction of the Peak response to the Startle stimulus given alone. Newborn rat reactivity could represent a useful and validated model in anxiety studies which could be moored with the Acoustic Startle Reflex (ASR) and PPI, appropriate models to study, in adulthood, particular neurological and psychiatric disorders showing deficits in attention and sensory-motor gating (Tourettes’ syndrome, obsessive compulsive disorders, Huntington’s disease and schizophrenia).

Research on neurobehavioral function of workers occupationally exposed to fluoride
SUMMARY: Sixty-five operations workers (all males) in an electrolytic aluminum production facility were divided into two groups. The first group of 37 was employed for more than 5 years, and the second group of 28 for 5 years or less. These men had no history of liver, kidney, or immune-related

Exposure to environmental neurotoxic substances and neurodevelopment in children from Latin America and the Caribbean.
Environmental (and occupational) exposure to neurotoxic substances is a worldwide problem that can affect children's neurodevelopment (ND). In Latin American and Caribbean (LAC) countries there are over 300 million children living under the threat of neurodevelopmental delays due to toxic environmental exposure. Large industrial centers, intense mining and agricultural activities,

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

Use of the Rey-Osterrieth Complex Figure Test for neurotoxicity evaluation of mixtures in children.
The aim of this study was to assess the value of the children's version of the Rey-Osterrieth Complex Figure Test as a screening test in a population exposed to different mixtures of neurotoxicants. Copy and Immediate Recall scores were evaluated through the test. Children were recruited from three sites; an

Experimental pharmacological researches regarding the influence of sodium fluoride in allopathic and homeopathic doses in central nervous system's performances. A correlation between behavioral response in classic maze test and morphological aspects of cerebral cortex
The influence of fluorine administration on central nervous system’s (CNS) performances in female mice treated during gestation with two distinct doses of sodium fluoride (NaF): 0.25 mg and 0.50 mg. The research extended also to offspring (generation 1 – F1), treated with NaF in allopathic (0.25 and 0.50 mg), homeopathic

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 78 studies reporting reduced IQ (75 studies with children and 3 studies with adults) and several on the impaired learning/memory in animals. And there are studies which link

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 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
