b. Conditioning as a cause of behavior.
c. The body and the mind are independent of each other.

areas.
b. fMRI is accurate with the moment of activity and with EEG you can see the active
areas.
c. EEG is accurate with the moment of activity and with fMRI you can see the specific
active neurons.
d. fMRI is accurate with the moment of activity and with EEG you can see the specific
active neurons.

immunological defense and the removal of dead cells. Of the (B) are three variants, these three
all aim to
