Study Notes

Neural Response to Emotions

The brain responds to emotions through networks of neural structures working together.
These networks can provide feedback to each other, allowing for modification of emotional responses based on learning.
Emotional responses have a strong biological basis, as evidenced by similar facial expressions and emotions in deaf-blind individuals.

The Initial Response

The brain shows emotion-dependent responses within 150 milliseconds of encountering a potential threat.
This rapid initial response tags or highlights the stimulus for further processing by brain structures involved in perception.
The brain prioritizes potentially threatening stimuli, directing attention towards them.

The Amygdala

The amygdala, located in the medial temporal lobes, plays a critical role in processing emotional stimuli, especially fear-relevant ones.
When the amygdala detects potentially threatening stimuli, it increases activity in sensory areas, enhancing attention to those stimuli.
The amygdala’s connections to other brain structures trigger observable emotional responses.

Autonomic Response: Fight or Flight

The autonomic nervous system controls the body's physiological response to emotions, consisting of the sympathetic and parasympathetic branches.
The sympathetic nervous system prepares the body for action (fight or flight) by increasing energy and alertness.
The parasympathetic nervous system calms the body and conserves energy when the threat has passed.

Emotional Response: Movement

The nervous system prepares the body for movement in response to emotion, possibly increasing the speed and efficiency of emotional responses.
Threatening stimuli increase activity in brain regions associated with movement planning and the spinal cord.

Emotional Regulation

The frontal lobes play a crucial role in emotional regulation, receiving input from the amygdala and sensory areas.
The frontal lobes evaluate the initial emotional response and determine if it's appropriate for the situation.
They can either reinforce the initial emotional response or decrease it, depending on the situation.

Experiencing Emotions

The James-Lange theory proposes that physiological reactions to stimuli precede emotional experiences.
This theory suggests that our feelings arise from our body's response to stimuli.
