Brain stem in which regulates heart rate and breathing no cannabinoid receptors, which confirms that THC does not exert influence on these functions in the direct sense. Their concentration in the hippocampus explains why marijuana leads to inhibition of memory (learning and memory). In animal studies, these findings are confirmed. It is shown that was not impaired ability to recall information in animals, but showed decreased possibility of their storage, ie. Creation of new memory and learning. The rats under the influence of marijuana have been equally poor results as well as the rats with a damaged hippocampus. These studies open the question of whether THC kills brain cells? The results showed that THC kills cells in the hippocampus, but to lead to a significant deterioration of his, had to use a large amount of THC in rats, as well as in laboratory isolated cells, that normal consumer of marijuana would not have got in you. Experiments on monkeys have shown no significant extinction neurons in long-term use, but these results do not apply to functional and chemical changes in the brain, which are especially detected in humans when used marijuana while the brain is developing in childhood and adolescence. The research will continue, but should take into account that although the results show no significant …show more content…
Runner highest concentrations of cannabinoid receptors has been found in the cells of the immune system. Animal studies have confirmed the reduction of the immune response to infection, but again in doses of THC that marijuana use beyond an ordinary consumer (Kuhn et al.,
