Brain Structure And Function | Brain Injury | British Columbia The brain structure is composed of three main parts: the forebrain, midbrain and hindbrain, each with multiple parts. Forebrain The Cerebrum: Also known as the cerebral cortex, the cerebrum is the largest part of the human brain, and it is associated with higher brain function such as thought and action. Functions Of The Lobes: Frontal Lobe – The frontal lobe lies just beneath our forehead and is associated with our brain’s ability to reason, organize, plan, speak, move, make facial expressions, serial task, problem solve, control inhibition, spontaneity, initiate and self-regulate behaviors, pay attention, remember and control emotions. Parietal Lobe – The parietal lobe is located at the upper rear of our brain, and controls our complex behaviors, including senses such as vision, touch, body awareness and spatial orientation. A deep furrow divides the cerebrum into two halves, known as the left and right hemispheres. Midbrain Hindbrain

Structure of the Human Brain: the Forebrain Find coupons, reviews and similar sites for any retailer The brain is a very complex structure. This article will discuss one the large sub-divisions, the forebrain. General Structure In general, the human brain can be divided in three large parts: The forebrain with the telencephalon, consisting out of the neocortex, the basal ganglia and the limbic system as most important structures, and the diencephalon, with the thalamus and hypothalamus as noteworthy structures. Figure 1: Divisions of the Brain The Telencephalon The telencephalon (also known as the cerebrum) is the largest part of our brain and controls voluntary movements and cognitive and emotional processes. It can be divided in: The neocortex, The basal ganglia, and The limbic system The two halves of the brain are quite distinct in function: The left hemisphere: language and analytic thinking. The neocortex The neocortex is characterized by two distinct furrows, the lateral and central furrow. Figure 2: Brain Lobes The basal ganglia x
Concealed carry in the United States Concealed carry or carrying a concealed weapon (CCW), is the practice of carrying a weapon (such as a handgun) in public in a concealed manner, either on one's person or in close proximity. Not all weapons that fall under CCW laws are lethal. For example, in Florida, carrying pepper spray in more than a specified volume (2 oz.) of chemical requires a CCW permit, whereas anyone may legally carry a smaller, so-called, “self-defense chemical spray” device hidden on their person without a CCW permit.[1][2] There is no federal law addressing the issuance of concealed-carry permits. All fifty states have passed laws allowing qualified individuals to carry certain concealed firearms in public, either without a permit or after obtaining a permit from a designated government authority at the state and/or local level. Some states publish statistics indicating how many residents hold permits to carry concealed weapons, and their demographics. History[edit] State laws[edit] Permitting policies[edit]
Cerebral Cortex The cerebral cortex is the layer of the brain often referred to as gray matter. The cortex (thin layer of tissue) is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white. The cortex covers the outer portion (1.5mm to 5mm) of the cerebrum and cerebellum. The portion of the cortex that covers the cerebrum is called the cerebral cortex. The cerebral cortex consists of folded bulges called gyri that create deep furrows or fissures called sulci. The cerebral cortex is divided into right and left hemispheres. continue reading below our video Loaded: 0% Progress: 0% Most of the actual information processing in the brain takes place in the cerebral cortex. Cerebral Cortex Lobes Parietal Lobe - involved in the reception and processing of sensory information from the body. Frontal Lobe - involved with decision-making, problem solving, and planning. Occipital Lobe - involved with vision.

Balagué, cliquer sur le lien ci dessus Les réseaux de Pétri, une méthode innovante pour modéliser un phénomène viral ou de buzz Le comportement des internautes est bien complexe…aujourd’hui, le Web n’est plus seulement une source de recherche d’informations, mais aussi un lieu d’expression, de jugements, d’expérience de nouveaux comportements, d’immersion dans des réseaux sociaux.. Deux éléments majeurs sont liés au développement de ces phénomènes: d’une part un nombre jamais égalé d’informations fournies par les internautes ; d’autre part une prépondérance des liens communautaires et des connections primant même sur le comportement individuel. Une exigence majeure apparaît aux chercheurs: la nécessité de comprendre, de modéliser et de simuler ces comportements complexes. Plusieurs théories s’affrontent sur le processus viral et les connections entre les internautes. Mais quel est l’avenir de ce type de modèles ?
Chapter 11: The Cerebral Cortex General Organization The cerebral cortex is the outer covering of gray matter over the hemispheres. This is typically 2- 3 mm thick, covering the gyri and sulci. Certain cortical regions have somewhat simpler functions, termed the primary cortices. These include areas directly receiving sensory input (vision, hearing, somatic sensation) or directly involved in production of limb or eye movements. The association cortices subserve more complex functions. The Neocortex Most of the cerebral cortex is neocortex. The neocortex represents the great majority of the cerebral cortex. Functionally, the layers of the cerebral cortex can be divided into three parts. The internal granular layer, layer IV, receives thalamocortical connections, especially from the specific thalamic nuclei. The infragranular layers, layers V and VI, primarily connect the cerebral cortex with subcortical regions. There are several identifiable cell types in the cerebral cortex.

La motivation La motivation La motivation est l’ensemble des causes, conscientes ou inconscientes, qui sont à l’origine du comportement individuel. En effet, la conduite humaine repose sur des choix conscients ou des pulsions auxquelles obéit l’inconscient. Les théories psychologiques distinguent d’une part la motivation « primaire », destinée à satisfaire les besoins de base (nourriture, oxygène, eau), et d’autre part la motivation « secondaire », qui incite l’individu à satisfaire ses besoins sociaux (compagnie, réussite, reconnaissance…) Les besoins primaires doivent être satisfaits et assurés pour que l’organisme puisse traiter les instincts secondaires. o Les behavioristes pensaient que l’organisme recherche la stimulation et qu’il se comporte de manière à favoriser l’état de non-stimulation. o D’un point de vue différent, les théories cognitives indiquent que l’être humain recherche plus à optimiser sa motivation qu’a la minimiser.
