Resting state
default mode network:
increased activity during resting
medial prefrontal cortex
posterior cingulate cortex
lesioned: simultagnosia -- unable to integrate visual info
posterior parietal cortex
hippocampus
lateral temporal cortex
definition: decreased activity brain areas
Attention
disorder: ADHD (attention deficit hyperactivity disorder)
smaller mPFC, basal ganglia
heritable
DA related -- stimulants
control attention: different circuits
Cortical + subcortical areas
pulvinar nucleus
frontal eye fields
types
exogenous (bottom-top): automatic reaction
salience map
visual areas -- LIP (lateral intraparietal cortex)
endogenous (top-down): directed by brain
priority map
frontal -- parietal
covert attention
consequences
increased visual sensitivity
speeding reaction times
fovea: a small depression in the retina where visual acuity is highest. The center of the field of vision is focused in this region,
macula: the central area of the retina and gives us the ability to see “20/20” and provides the best color vision.
retinotopic shift
definition: ability to focus on one aspect of sensory input
example: cocktail party effect (selective attention)
Consciousness
challenges
small steps in studying neural correlates of consciousness
hard to interpret NCC data
experience?
perspectives
matter cover mind (materialist)
matter and mind are separated (dualism)
binoculary rivalry
Hypotheses of brain function
sentinel:
always be on the lookout
monitor environment
internal mentation:
thinking about oneself
thinking and remembering
imaging induce
neglect syndrome:
lesion of lateral intraparietal cortex
