Full textExposure to electromagnetic fields has arisen in recent decades a large concern. In parallel, many symptoms experienced by some people have been attributed to this factor. The central nervous System is the most integrative tissue for information, and if a sensitivity to electromagnetic fields exists, it is likely to manifest itself on this System. The aim of this work was to study as a first step the effect of two types of electromagnetic fields, a static magnetic field and a radio frequency GSM 900 MHz, on the behavior in rats (anxiety, memory and attention). Then, biological effects of exposure to GSM 900 MHz signal to specific absorption rates of 1. 5 or 6 W/Kg were sought in the central nervous System: on oxidative stress, on oxidative metabolism and on glial cells. Our results show that sub-acute exposure to a static magnetic field of 128 mT did not disturb emotional behavior and recall process in rats, despite a trend towards a decrease in performance. Similarly, a sub-chronic (2 months) and chronic (6 months) "head only" exposure to GSM signal did not disturb learning and memory in rats. However, exposure to GSM 900 MHz signal (DAS 6 W/kg) induced: i) a disturbance of the antioxidant enzymes activity ii) a change in neuronal activity by a change in the activity of the cytochrome c oxidase iii) a reactive astrogliosis (increased GFAP expression) in the brain of exposed rats. Astrogliosis may be associated with underlying neuronal damage. Given the morphological differences between rats and humans, the SAR calculated from an individual as defined in the recommendations and standards, would be equal to four times the average SAR in the rat brain, making the extrapolation of these results to humans reassuring

Full textThe gastro-intestinal tract hosts a complex microbial community, the gut microbiota, whose collective genome coding capacity vastly exceeds that of the host genome. The involvement of the gut microbiota in various aspects of the host physiology, such as the nutritional metabolism and the immunity, has long been studied. In contrast, the possible action of the gut microbiota on brain development and functioning is a new line of research, still poorly explored. In this context, we performed a first general study of the effect of gut microbiota on the brain by comparing the sensory-motor functions, the anxiety-like behaviour, the activation of the hypothalamic-pituitary-adrenal axis and the brain monoamine profile in germ-free and conventional F344 rats. The results show that, in this particularly stress-sensitive strain, absence of gut microbiota exacerbates the anxiety-like behaviour and neuroendocrine response to stress, and reduces brain dopamine metabolism. To investigate the means by which the microbiota can affect the brain, a second study was conducted, targeting a specific bacterial metabolite, indole, whose oxidative derivatives, produced by the liver, are known to have neuroactive properties. Indole is a natural metabolite of the gut microbiota, whoseoverproduction could occur during a microbiota dysbiosis. Two conditions of overproduction, namely chronic and acute, were modelled. In both cases, significant changes in the behaviour of the host were observed. In chronic overproduction, indole promotes anxiety- and depressive-like behaviours, while acute overproduction has a marked sedative effect. From a mechanistic point of view, we confirm that indole can act on the central nervous system through its oxidized derivatives and show for the first time that it can also act by activating the brain nuclei of the vagus nerve

Full textThe aim of this work was to study emotional behaviours in rats. This was done by comparing control rats with rats that have been stimulated during infancy (i. E. Postnatal handling) according to an ethoexperimental approach. The observation of risk assessment and approach / avoidance behaviours allowed the demonstration that postnatal handling effects are specifically related to a decrease in anxiety-like behaviours, independently from a more general effect on activity level. In addition, we demonstrated that postnatal handling does not modify defensive reactions during a cat confrontation, but have some effects after the confrontation. This result confirms the existence of a predator innate recognition and suggests that the control of defensive reactions is initially under the control of cerebral structures that are not affected by postnatal handling. The discussion of our results is based on the different components of emotional reactivity

Full textOn a general level of nasal obstruction is manifested by hypoxia and hyposmia. In mammals,olfactory cues are paramount in the learning of foreign or familiar smells and the choice of sexual partner. The purpose of this experimental work is to study the short and long term bilateral nasal obstruction of 3 days in a mammal altricial. Faced with hyposmia young, the mother increases her care activity. More young people have difficulties in orientation breasts and therefore growth retardation associated with a decrease of milk ingested. These disturbances are associated with decreased plasma levels of thyroid hormones, and increased levels of testosterone, and corticosterone greater for females. In addition to the passage mouth breathing leads to dehydration, atrophy of the lungs and olfactory bulbs, an adaptation of the respiratory muscle fibers orofacial development and articulation of complex nasomaxillaire adapted to an opening of the mouth frequently. Moreover, the results show a long-term influence on exploratory behavior during the search of sexual partners among males. We have shown that bilateral nasal obstruction of three days in a mammal unweaned causes short-and long-term, both behavioral and endocrine morphology

Full textFeeding behavior is highly regulated by homeostatic and hedonic systems The motivational, consummatory and anticipatory components of this behavior appear to be differentially regulated by opioids and dopamine. Our study is aimed first to characterize the motivational, anticipatory and consummatory components of feeding taking into account food palatability and homeostatic state of the animals ; and second, to study the implication of the opioid and dopaminergic systems on the control of these different components. Our results reinforce the idea that the opioid system regulates feeding through the modulation of food palatability perception. The dopaminergic system seems to be more implicated in the regulation of the anticipatory activity related to very relevant stimuli. Also, it may allow the evaluation of the cost/benefits to perform a given action
