What are the 2 variables of the neuroscience wheel of emotions ?

The ability to display emotions and recognize them in others transcends _____and _____barriers
Cultural and linguistics
Genuine, automatic, involuntary facial expressions sometimes involve different facial _____ than artificial expressions of emotions
Muscles
Condition where people cannot voluntarily control their facial muscles (due to damage in or around primary motor cortex)
Volitional facial paresis
Condition where people do not show automatic facial expressions of emotion, but they have no trouble voluntarily moving facial muscles. This is often seen in Parkinson’s Disease.
Emotional facial paresis
What are behavioral responses to emotions ?
Muscular movements
What system controls autonomic responses to emotions ?
Peripheral nervous system (fight or flight, energy)
What do hormonal responses to emotions signal through ?
Blood
Hormonal responses reinforce ______ responses
Autonomic
What is anthropectomy ?
The denial that animals exhibit humanlike characteristics.
Defense mechanisms in animals are linked to what emotion ?
Fear
What is this called : put metal wire in brain and give on/off switch to animals to self stimulate their own brain
Intracranial self-stimulation
Self electrical stimulation always ______dopamine levels
Increases
Is correlation between dopamine signaling and pleasure strong or poor ?
Poor
What type of learning is dopamine linked to ?
Association learning
Smelling the right pheromone triggers what type of behavior in rodents ?
Sexual behavior
Stimulating GABA neurons in the medial amygdala of the posterior dorsal division causes what behaviors ?
Try to have sex and extreme rage
Stimulating Glutamate neurons in the medial amygdala of the posterior dorsal division causes what behaviors ?

The 25 unique emotion blends result in what type of expressions ?
Multimodal behavioural expressions involving voice, touch, posture, gaze, and head/body movement
What are the 3 steps of the theory of emotions ?
- Perception of emotion-eliciting event/stimuli
- Subjective feelings of emotion
- Behavioral and physiological responses
People with damage to what peripheral structure feel emotions less intensely ?
Spinal cord

People could exhibit behaviors but not feel emotions
What are the 3 steps of the James-Lange theory ?
- Perception of emotion-eliciting event
- Collection of behavioural and physiological responses are triggered by the brain unconsciously
- Feedback from the peripheral nervous system to the brain triggers subjective feelings of emotion (e.g., fear).
