The limbic system
According to Paul MacLean (1958), theoretician of a brain into three parts according to evolutionary criteria, the limbic system is the pale-mammalian brain, the seat of motives and emotions. It is able to respond to this information by using the memory of past information. Therefore involved in emotional processing, learning and memory.The limbic system is formed by a complex combination of nerve centers and their communication channels that border (border says Latin limbus) the brain-stem. This system, which is located at the base of the cerebral cortex, is part of a functional neuroanatomy together great limbic lobe appointed by Paul Broca in 1878 (see fig. 1). Two pairs and symmetrical nerve structures, located in the middle regions of the brain are at the heart of emotional processes: the hippo-campus and the amygdala. The first is responsible for land management and relational maps about the world. He is also heavily involved in the formation of memories. The second is buried deep within each temporal lobe. Both tonsils used to recognize emotions including fear on the face of the other, to express and to develop packaging associated with situations that are themselves nothing scary. With these structures, the subject learns to associate the pleasure and pain to an object or situation and estimate the intensity and value (hedonistic or aversive) of a stimulus.
