Thus, physical evidence has revealed that the right hemisphere, while indeed the brain's more "emotional" side, is not solely responsible for processing the expression of emotions.
A paired, almond-shaped structure deep within the brain, the amygdala integrates emotions, emotional behavior, and motivation.
Language functions, in the majority of the people, are lateralized to the left hemisphere, whereas emotion, especially negative emotion, attention and arousal seem to be lateralized to the right hemisphere.
Parents of both sexes showed a greater activation in the amygdala to cries than to laughter [106]. One study in which cry sounds were produced by adult actors, found that the right amygdala was activated to a greater extent than the corresponding region in the left hemisphere [101].
The frontal lobe is at the front of the head and is responsible for planning, organisation, logical thinking, reasoning, and managing emotions. This is the part you will hear about most regarding the expression and regulation of emotions and behaviors.
Children who have stronger left-brain functions tend to be more analytical in their thinking and typically perform well academically. They may have a great ability to memorize large amounts of data, have a large vocabulary, and are detail-oriented.
Sadness is associated with increased activity of the right occipital lobe, the left insula, the left thalamus the amygdala and the hippocampus. The hippocampus is strongly linked with memory, and it makes sense that awareness of certain memories is associated with feeling sad.
The neural system for emotions linked to approaching and engaging with the world – like happiness, pride and anger – lives in the left side of the brain, while emotions associated with avoidance – like disgust and fear – are housed in the right.
The hypothalamus acts as a regulator of emotion, controlling levels of sexual desire, pleasure, aggression and anger.
Depression is associated with an inter-hemispheric imbalance; a hyperactive right-hemisphere (RH) and a relatively hypoactive left-hemisphere (LH). Nevertheless, the underlying mechanisms which can explain why depression is associated with a RH dominance remain elusive.
The amygdala is responsible for the expression of fear and aggression as well as species-specific defensive behavior, and it plays a role in the formation and retrieval of emotional and fear-related memories. (Fig. 2 depicts the amygdala's involvement in fear circuitry).
Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving.
The amygdala—the brain region that regulates emotion and motivation—uses about two-thirds of its neurons to detect bad news, Hanson wrote. Think about this: two-thirds of your motivation regulator is designed to focus on negativity.
1) Increasing negative and positive emotion engaged primarily left-lateralized prefrontal regions, whereas decreasing emotion activated bilateral prefrontal regions.
Wright and Hardie (2012) found that left-handers reported higher levels of state anxiety but there was no difference in trait anxiety. They also demonstrated that when Trait Anxiety was controlled for, left-handers still showed a higher level of state anxiety compared to right-handers.
For example, the DongUiBoGam states the following: “Liver is in charge of anger, heart is in charge of happiness, spleen is in charge of thoughtfulness, lungs are in charge of sadness, and kidneys are in charge of fear.” The quantification of the terms used to explain the relationships between emotion and bodily organs ...
According to an fMRI study, decreased brain activity in the hippocampus was reported82 in depressive patients. Reduced gray matter volume and reduced functional activity in the hippocampus would lead to negative emotion and the inability of cognitive processing in depressive patients.
The ALE analysis indicated that pain with concomitant depression was associated with the right amygdala, while depression with concomitant pain was related primarily to the left dorsolateral prefrontal cortex (DLPFC).
So what are so-called "right-brained people" like? They are often described as being more emotional, intuitive, and creative. They are often described as doing well in careers that involve creative expression and free thinking, such as becoming an artist, psychologist, or writer.
They often neglect the left side of the body, and they're not able to see things on the left. These people are often impulsive and make poor decisions. They also have a short attention span, and their ability to read, process some elements of language [3] or learn new things is slowed down.
Left hemisphere brain damage can lead to:
Trouble reading and writing. Changes in speech. Deficits in planning, organization, and memory as those skills relate to language. Weakness or lack of movement on the right side of the body.
The Prefrontal Cortex (PFC) and hippocampus are the most critical parts of the human brain for decision making.
