BRAIN REWARD SYSTEM. The brain reward pathway is indispensable to the survival because it associates the execution of vital functions with strong sensations of satisfaction. The ventral tegmental area VTA, receives informations which indicate the level of satisfaction, then analysis and transmits this information thanks to a chemical messenger, the dopamine, to the nucleus accumbens, the septum, the amygdala and the prefrontal cortex. The nucleus accumbens acts on the striatum which commands our

SYNAPSE. SYNAPSE LTP (long-term potentiation). Mechanism of LTP (long-term potentiation), which plays a role in learning. Stage 1 (See images no. 11969 05 and 11970 05 for stages 2 and 3). In response to a stimulus (sight, taste, touch, etc.), an electrical signal is produced which triggers the release of massive quantities of glutamate (purple triangles) by the presynaptic element. This in turn triggers a massive release of calcium (red spheres) in the dendrite (postsynaptic element), se

BRAIN, SCAN. BRAIN, SCAN The brain is divided into two hemispheres bridged by a mass of nerve fibers, the corpus callosum. The brain as a whole (encephalon) is composed of these areas along with the brain stem (the prolongation of the spinal cord), and the cerebellum (a sort of branch circuit located in the posterior region of the skull). Deep grooves separate the brain into lobes designated by the names of the overlying skull bones: frontal, parietal, temporal, occipital. Seen here, a normal
