Study Notes

Emotions

Emotions are feelings, behaviors, and physiological changes that are characterized as affective states, which can be positive, negative, or neutral.
There are several limitations in the study of emotions, including the lack of clear mapping of emotions onto the brain, the error of reification, and the difficulty of investigation.

The James-Lange Theory

The James-Lange theory states that feelings are secondary to physiological responses, and emotional experiences result from somatic and visceral responses.
The thalamus and amygdala play key roles in the processing of emotional stimuli.

The Facial Feedback Hypothesis

The facial feedback hypothesis suggests that facial expressions can induce emotions, and changes in facial muscles can trigger emotional responses.
Smiling can decrease heart rate, while frowning can increase heart rate.
Botox, which paralyzes facial muscles, can reduce emotional feelings, supporting this hypothesis.

Evolutionary Purpose of Emotions

Emotions are innate and have evolved from animal emotions to increase chances of survival.
Emotions also play a crucial role in communication, sometimes replacing behavior, such as growling instead of attacking.

Communication and Emotions

The zygomaticus major and corrugator supercilii muscles are activated when exposed to happy and fearful bodily and facial expressions, respectively.
The amygdala recognizes emotion, primarily fear, by looking at eyes.
Auditory emotional recognition is possible in individuals with pure word deafness.
Mirror neurons in the somatosensory cortex may be involved in emotion recognition.

Lateralization and Emotion

The left side of the face generally expresses more emotions, considered an evolutionarily conserved function.
Lesions in the right hemisphere impair emotion expression.
Different emotions are processed and expressed in the brain separately, without one necessarily influencing the other directly.

Disorders and Emotions

Volitional facial paresis is a disorder that affects voluntary muscle movement to show emotion.
Emotional facial paresis is a disorder that affects involuntary muscle movement to show emotion.

Autism Spectrum Disorder (ASD)

ASD is a heterogeneous condition characterized by altered brain development, with more than 100 associated genes involved in neurodevelopment and neuronal communication.
Common symptoms of ASD include altered social interactions, communication, and repetitive behaviors.
The sex ratio for ASD is 4:1, with males either being more susceptible or females not being diagnosed.
