Interoception (Lecture slides) Flashcards

6121727275	What is interoception	-Perception of one's own internal physical state -Monitoring integrity of internal body state, some examples -temp -pain -itch -hunger	0
6121742921	Exteroception	Stimulus from outside body	1
6121755018	proprioception	signals from skin and musculoskeletal (joints, tendons, muscles)	2
6121760084	What components make up Interoception	Proprioception and visceroception	3
6121775434	key features of interoception	- strong incentive motivational component (urges e.g. blinking, thirst, sneezing) - relative preference assessment (what feels "good" e.g. optimal body temp)	4
6121889396	what was most activated for interoception perception	insula cortex and some of SMA	5
6121895693	what was correlated with accuracy for the heart and note task	activation of anterior insula	6
6121904123	what neural systems underly interoception	thalamas sends projections to posterior insula, anterior cingulate cortex and somatosensory cortex	7
6121916959	microscopic divisions of the insula	granular, dysgranular, agranular	8
6121934410	major macroscopic divisions of insula	posterior (secondary sensory cortex topographic organization of interoceptive afferents) anterior (re-representation and multi-modal integration of interceptive afferents)	9
6121964103	brain of meditators	shown to have greater grey matter thickness in insula and prefrontal cortex (only significant with older age)	10
6121979583	damage to insula does what to smokers	more likely to quit smoking and remain abstinent - no longer experience conscious urges to smoke after quitting	11
6121757561	visceroception	signals from the inner organs (mechano, chemo, thermo, osmoreceptors)	12
