Q

salience network

A

most active when a behavioral change is needed

17
Q

if salience network is not functioning properly…

A

default network shows excessive activity

18
Q

effects of excessive activity in default network

A

lapses in attention in ACC and insula

19
Q

attention networks

A

dorsal attention system, fronto-parietal executive networks

20
Q

fronto-parietal executive networks

A

DLPFC (dorso-lateral pre-frontal cortex), IPS (intraparietal sulcus)

21
Q

attentional system induces ____ across a population of neurons that assess some sensory signal

22
Q

increasing activity in the attention network increase _____ globally

A

brain synchrony

23
Q

increasing activity in the default network may ____

A

have a loss of global synchrony

24
Q

how does our brain choose important events from among all ongoing sensory info?

25
meditation reduces activity in
default mode network
26
meditation increases
DM, salience, and central executive network connectivity
27
meditation increases activity in what part of the brain
anterior cingulate cortex (ACC)
28
bottom-up
stimulus provoking - i.e., seeing a naked person, Baltimore picture ~ seeing the bright building, consciousness
29
top-down
based on own knowledge, experience, expectation, controlling focus - i.e., seeing someone you're in love with, Baltimore picture ~ pointing out the aquarium you used to go to, attention
