Illustration of the areas of the brain that are active while taking a written test. The reading area (light blue area) is activated and the prefrontal cortex (small red area) activates the working memory, reasoning and language. The temporal lobe (green area) activates short-term memory. The visual cortex (pink area) is activated to a greater or lesser extent depending on the test and the motor cortex (orange area) activates the hand.

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 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
