Lecture 7 Flashcards
why do we use mri
to understand brain responses to different stimulus
ex: thermal stimulation
what do we call the brain sections that we use to study
voxels
when was the first brain imaging study study of pain and what did they find
1991
-pain is represented in pain
-it is not localized in a singles spot
true or false: pain is localized in a single spot
false, it is not localized in a single spot
nociceotive input from spinal cord has 2 paths
-thalamus: arousal, autonomic and somatomotor activation
-parabrachial: amygdala aja
brain models for modulation of pain by attention and emotions have different pattern recognition
true
you can detect patterns
you can infer stimulus from the pattern
true or false; fibromyalgia amplifies pain processing
true
who discovered placebo
henry beecher
what dies dlPCF
goal context; expectancy
what is vmPFC
meaning schema
true or false: placebo reduces pain
true
what was in the re analysis of individual brain activations for placebo
-dPFC
-dlPFC
what di we use mri for?
-t1 weighted images
-diffusion weighted images
-resting state images
what do we use resting stat functional connectivity for translational neuroimaging
for connection studies
why do we need more people in studies
when sample size is smaller. then it seems like it success because you see big changes
-bogger samples would show smaller differences
