Emotions Dr. Piasecki Flashcards
(93 cards)
Where do we find emotions?
in the amygdala
What is a major structure leading to patterns of physiological change which pause when emotions occur?
amygdala
How come we can have an emotion reaction/response before we’re aware of what’s going on?
becuas their is a connection to the thalamus to cortex to amydala
The innermost part of the brain is about (blank)
survival
What do emotions do for us?
help us respond to important situations and to convey our intentions to others
The voluntary smile is driven by?
motor cortex, pyramidal tracts
What is the involuntary smile driven by?
motor areas in ant cingulte, extrapyramidal, reticular activating system
What is your emotional response driven by?
subjective
autonomic
What parts of your brain contribute to your emotional response?
structures
pathways
what is the emotional motor system?
subective experience-> visceral and somatic motor response
What is a primary emotion experienced by all social animals that creates a visceral motor and somatic motor response?
fear
How do you measure fear in animals?
heart rate and blood pressure salivation respiratory rate scanning startle urination/defecation freezing
What is the brains shortcut for emotions?
it can directly hit up the amygdala from the thalamus and bypass the visual cortex
how do humans respond to fear?
heart pounding or racing dry mouth pale skin respiratory rate hypervigilance increased startle urination/diarrhea apprehensive expectation
What are the brain structures that mediate emotion?
hypothalamus limbic system (limbic cortex, amygdala) brainstem nucleus accumbens prefrontal cortex
What does the hypothalamus function in?
light dark cycle
temperature regulation
neuroendocrine
integral in emotion and sexual behaviors
What do the removal of the cerebral hemispheres show?
showed that the hypothalamus integrated emotions and behaviors
What kind of emotion is experienced with ablation of just the cerebral hemispheres? Of the cerebral hemispheres AND the hypothalamus?
rage, attack with just the hemispheres
Docility with the hemispheres and hypothalamus
What is the the route information takes to go through the hypothalamus?
input form cortex (relatively unprocessed)
output to brainstem’s reticular formation
What is the link between higher cortical activity and the “lower” systems that control emotional behavior?
limbic system
What makes up the limbic system?
the limbic lobe and deep lying structures (amygdala, hippocampus, mamillary bodies)
What are considered the deep lying structures of the limbic system?
amygdala, hippocampus, mamillary bodies
What allows you to have the duchenne smile?
cingulate gyrus
What is this:
primitive cortical tissue with a cingulate gyrus and parahippocampal gyrus
limbic lobe
