Flashcards in Emotions Dr. Piasecki Deck (93)
Where do we find emotions?
in the amygdala
What is a major structure leading to patterns of physiological change which pause when emotions occur?
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)
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?
What parts of your brain contribute to your emotional response?
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?
How do you measure fear in animals?
heart rate and blood pressure
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
What are the brain structures that mediate emotion?
limbic system (limbic cortex, amygdala)
What does the hypothalamus function in?
light dark cycle
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?
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?
What is this:
primitive cortical tissue with a cingulate gyrus and parahippocampal gyrus
Where is the limbic lobe located?
encircles the upper brain stem (around corpus callosum)
what does the limbic system do?
integrates info about emotional content from cortical association areas
What happens if you remove an aggressive monkeys amygdala?
they become docile, horny and compulsive
What is kluver bucy syndrome?
it is severe temporal lobe damage, specifically to the AMYGDALA that results in visual agnosia, apathy/placidity, disturbance in sexual function, dementia, aphasia, amnesia
What are these a part of
orbital and medial prefrontal cortex (PFC)
nucleus of thalamus
