The Emotional Brain

Más información sobre el libro

What happens in our brains to elicit emotions like fear, love, and joy? Are we in control of our emotions, or do they govern us? Joseph LeDoux delves into the origins of human emotions, revealing that they are part of complex neural systems evolved for survival. Emotions, he explains, originate deep within the brain, distinct from conscious feelings. As a leading authority in neural science, LeDoux uncovers the mechanisms responsible for our emotions, many of which are just beginning to be understood. Notably, our brains can detect danger before we even feel afraid, initiating physical responses such as heart palpitations and muscle tension prior to conscious awareness of fear. LeDoux argues that conscious feelings are largely irrelevant to how the emotional brain functions. Emotional responses are hard-wired into our brain's circuitry, while the stimuli that evoke these emotions are learned through experience. This insight may be crucial for understanding and potentially altering our emotional makeup. Many psychiatric issues, like phobias and posttraumatic stress disorder, stem from malfunctions in how emotion systems learn and remember. By grasping how these mechanisms operate, we can reshape our self-perception and improve our approach to emotional disorders.
