Effects of GRF on paraventricular neurons in slices of guinea-pig hypothalamus.

abstract：:In previous studies on Alzheimer's patients it was shown that, in frontal and parietal locations, delta and theta responses of AD patients were greatly reduced. The present study analyzed coherence functions in these highly affected frontal and parietal areas. Visual sensory and event related coherences of patients wi...
