Affective neuroscience is the study of how the brain processes emotions.This field combines neuroscience with the psychological study of personality, emotion, and mood. [1] The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.
Limbic resonance is the idea that the capacity for sharing deep emotional states arises from the limbic system of the brain. [1] These states include the dopamine circuit-promoted feelings of empathic harmony, and the norepinephrine circuit-originated emotional states of fear, anxiety and anger. [2]
The consciousness and binding problem is the problem of how objects, background, and abstract or emotional features are combined into a single experience. [1] The binding problem refers to the overall encoding of our brain circuits for the combination of decisions, actions, and perception.
He postulated the limbic system as the brain's center of emotions, including the hippocampus and amygdala. Developing observations made by Papez, he hypothesized that the limbic system had evolved in early mammals to control fight-or-flight responses and react to both emotionally pleasurable and painful sensations.
Instead, the empirical evidence suggests that what exists in the brain and body is affect, and emotions are constructed by multiple brain networks working in tandem. [5] [6] Most other theories of emotion assume that emotions are genetically endowed, not learned. Other scientists believe there are circuits in the brain: an anger circuit, a fear ...
These stimuli activated not only the hippocampus but also other brain structures. He theorized that these brain structures worked together as the emotional control center in the brain and consequently founded the Papez circuit. [19] Because of these studies, Papez strongly believed that the circuit was the cortical control of emotion.
The theory of constructed emotion (TCE) offers an explanation of the basis of emotion by formulating the brain as a running internal model that controls central pattern generators in order to maintain allostasis. This theory argues that the computational goal of the brain is to minimize the prediction error, unpredicted events, that arise in a ...
As explained in his 1996 book, The Emotional Brain, [2] LeDoux developed an interest in the topic of emotion through his doctoral work with Michael Gazzaniga on split-brain patients in the mid-1970s. [3] Because techniques for studying the human brain were limited at the time, he turned to studies of rodents where the brain could be studied in ...
