cerebral cortex Flashcards
1
Q
- Describe the architecture of the cerebral cortex and the relationship between cortical architecture and the generation of electrical potentials measured by the EEG.
A
field potentials with neurons firing in synchrony in cortex give us eeg readings
2
Q
- Identify the basic classification of EEG rhythms, and their rough correspondence to different behavioral states
A
Delta
3
Q
- Recognize how rhythmically bursting and randomly discharging families of brainstem and thalamic neurons select and stabilize particular EEG patterns that relate to states of arousal and attention
A
reticular activating ssystem and the thalamus can conduct neurons to a pattern
4
Q
how many layers does isocortex have?
A
6
5
Q
what % of cortical neurons are inhibitory?
A
20
6
Q
if pre fires before post do we have LTP or LTD
A
LTP
7
Q
what layers are involved in feedforward information
A
4 and 3
8
Q
what layers are involved in feedback
A
1,2,5,6 (back propogation of error
9
Q
neurons that oscillate together fire together
A
makes certain steady states
