Emotional lateralization is the asymmetrical representation of emotional control and processing in the brain. There is evidence for the lateralization of other brain functions as well. Emotions are complex and involve a variety of physical and cognitive responses, many of which are not well understood. The general purpose of emotions is to ...
Depression may be related to abnormalities in the circadian rhythm, [22] or biological clock. A well synchronized circadian rhythm is critical for maintaining optimal health. Adverse changes and alterations in the circadian rhythm have been associated with various neurological disorders and mood disorders including depression. [23]
Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction. [2] The limbic system is involved in lower order emotional processing of input from sensory systems and consists of the amygdala, mammillary bodies, stria medullaris, central gray and dorsal and ventral nuclei of Gudden.

This gene polymorphism promotes hyperactivity of the amygdala through decreased pre-frontal cortex activity following the exposure to negative stimuli. [34] The pre-frontal cortex (PFC) plays a key role in assessing stimuli, decision-making and inhibiting behaviour as a result of emotional processing of the amygdala. [35]
The neurocircuitry that underlies executive function processes and emotional and motivational processes are known to be distinct in the brain. However, there are brain regions that show overlap in function between the two cognitive systems. Brain regions that exist in both systems are interesting mainly for studies on how one system affects the ...
Increased Anxiety Levels: Per Hafeez, watching disturbing news can trigger the amygdala, the brain’s fear center, by activating your fight-or-flight response. She explains, “That constant flow ...
MacLean redefined the circuit as the "visceral brain" which consisted of the limbic lobe and its major connections in the forebrain – hypothalamus, amygdala, and septum. Over time, the concept of a forebrain circuit for the control of emotional expression has been modified to include the prefrontal cortex.
Researchers found that the grey matter volumes of the amygdala — the part of your brain responsible for processing emotional responses — is negatively associated with social media addiction ...
