13. Hallucination-inducing vs. control stimulation:
fMRI connectivity between LGN and cortex changed
from a positive to negative relationship while EEG
connectivity between occipital and other brain
regions increased
Switch by LGN neurons from tonic to burst mode, hallucinations
occur because of temporary “blindness”. During burst firing
mode, certain aspects of the visual field do not reach the visual
brain because of the uncoupling of activity in the LGN and
cortex.
