Neurobiological effects of physical exerciseThe neurobiological effects of physical exercise are numerous and involve a wide range of interrelated effects on brain structure, brain function, and cognition. A large body of research in humans has demonstrated that consistent aerobic exercise (e.g., 30 minutes every day) induces persistent improvements in certain cognitive functions, healthy alterations in gene expression in the brain, and beneficial forms of neuroplasticity and behavioral plasticity; some of these long-term effects include: increased neuron growth, increased neurological activity (e.
Animal testing on rodentsRodents are commonly used in animal testing, particularly mice and rats, but also guinea pigs, hamsters, gerbils and others. Mice are the most commonly used vertebrate species, due to their availability, size, low cost, ease of handling, and fast reproduction rate. TOC In the UK in 2015, there were 3.33 million procedures on rodents (80% of total procedures that year). The most common species used were mice (3.03 million procedures, or 73% of total) and rats (268,522, or 6.5%).
Chronic painChronic pain is classified as pain that lasts longer than three months. In medicine, the distinction between acute and chronic pain is sometimes determined by the amount of time since onset. Two commonly used markers are pain that continues at three months and six months since onset, but some theorists and researchers have placed the transition from acute to chronic pain at twelve months. Others apply the term acute to pain that lasts less than 30 days, chronic to pain of more than six months duration, and subacute to pain that lasts from one to six months.
Stress managementStress management consists of a wide spectrum of techniques and psychotherapies aimed at controlling a person's level of stress, especially chronic stress, usually for the purpose of improving everyday functioning. Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health, such as headaches, chest pain, fatigue, and sleep problems, as well as depression.
Adult neurogenesisAdult neurogenesis is the process in which neurons are generated from neural stem cells in the adult. This process differs from prenatal neurogenesis. In most mammals, new neurons are born throughout adulthood in two regions of the brain: The subgranular zone (SGZ), part of the dentate gyrus of the hippocampus, where neural stem cells give birth to granule cells (implicated in memory formation and learning). The subventricular zone (SVZ) of the lateral ventricles, which can be divided into three microdomains: lateral, dorsal and medial.
Réaction aiguë au stressUne réaction aiguë au stress, également nommée réaction aiguë à un facteur de stress (dans la CIM-10), choc psychologique ou choc, est un phénomène psychique causé par un violent événement traumatisant ou terrifiant. Elle se manifeste par des symptomes physiques et psychiques, notamment l'incapacité de penser et réagir à la situation. S'il n'est pas ensuite correctement ressenti, pensé et intégré (« digéré »), le choc psychique se transforme en trouble de stress post-traumatique.
Occupational stressOccupational stress is psychological stress related to one's job. Occupational stress refers to a chronic condition. Occupational stress can be managed by understanding what the stressful conditions at work are and taking steps to remediate those conditions. Occupational stress can occur when workers do not feel supported by supervisors or coworkers, feel as if they have little control over the work they perform, or find that their efforts on the job are incommensurate with the job's rewards.
ApprentissageL’apprentissage est un ensemble de mécanismes menant à l'acquisition de savoir-faire, de savoirs ou de connaissances. L'acteur de l'apprentissage est appelé apprenant. On peut opposer l'apprentissage à l'enseignement dont le but est de dispenser des connaissances et savoirs, l'acteur de l'enseignement étant l'enseignant.
Rat-baitingRat-baiting is a blood sport that involves releasing captured rats in an enclosed space with spectators betting on how long a dog, usually a terrier, takes to kill the rats. Often, two dogs competed, with the winner receiving a cash prize. It is now illegal in most countries. In 1835, the Parliament of the United Kingdom implemented an act called the Cruelty to Animals Act 1835, which prohibited the baiting of some animals, such as the bull, bear, and other large mammals.
Trouble d'apprentissageLe trouble des apprentissages, ou trouble d'apprentissage est un dysfonctionnement dans le processus d'acquisition des connaissances. Il peut être d'origine psychologique, cognitif, voire psychomoteur. Il est spécifique à la fonction cognitive touchée : il y a donc des troubles d'apprentissage reliés au langage, à l'attention, mais aussi à des compétences spécifiques comme la lecture, l'orthographe, l'arithmétique La classification actuelle le place parmi les troubles neurodéveloppementaux.
