Excessive alpha 1-antichymotrypsin (ACT) in brain has been postulated to play a role in the pathogenesis of Alzheimer's disease (AD). We measured serum ACT by radial immunodiffusion in 57 patients with presumed AD, 110 healthy controls (24 children; 86 adults), 67 non-AD patients from a geriatric private practice and a VA nursing home, and 136 asthmatics(More)
The Klüver-Bucy syndrome is a well known consequence of lesions of the temporal lobe, but the neural mechanisms remain obscure. To elucidate the neurochemical changes in this syndrome, we utilized in vivo microdialysis of amygdala and hypothalamus in two Cebus monkeys (C. apella) before and after bilateral lesions of the temporal pole (TP). Both subjects(More)
We report changes in quantitative electroencephalography activity in a male tinnitus patient when his tinnitus suddenly disappeared. Topographical illustration of the quantitative electroencephalography data showed beta foci in T3 and C4 with tinnitus, which resolved on spontaneous remission of the tinnitus. Comparison of the power spectra in the presence(More)
A study was undertaken to gain an understanding of the biochemical mechanism whereby tetrabenazine (TBZ) produces a sedative effect on the locomotor activity of rats. Rats injected with L-5-hydroxytryptophan (L-5-HTP, 30 mg/kg), the immediate precursor of 5-hydroxytryptamine (5-HT), showed the characteristic bison appearance, pitosis, and catalepsy normally(More)
The influence of 1 mM-L-proline on electrically stimulated release of endogenous glutamate from slices of rat frontal cortex was measured. One mM-L-proline approximates the in vitro concentration that inhibits glutamate-induced spreading depression. Also, this L-proline level has been reported to be present in brain after an intraperitoneal injection that(More)
The gastric enterochromaffin-like (ECL) cell plays a major role in the regulation of gastric acid secretion. We have previously described that Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) is present on myenteric neurons in the rat and colocalizes with its high-affinity receptor, PAC1, expressed on the surface of gastric ECL cells. The study of(More)
This study was conducted in an attempt to determine the efficacy of neurofeedback (NFB) in the treatment of patients suffering from vertigo or tinnitus. Results indicated that after NFB, power for delta and theta bands was reduced; however, an increase of power was noted for the alpha bands. Furthermore, normalization was observed for the vestibular evoked(More)
BACKGROUND previous research has been inconclusive about the nature of hemispheric asymmetry in emotional processing. METHOD 13 patients with DSM-IV bipolar disorder received repeated QEEGs over 2 years in different mood states. Z-score measures of asymmetry were assessed. RESULTS asymmetry in frontotemporal slow-wave activity appeared to be in opposite(More)
This study was conducted in an attempt to determine whether the quantitative electroencephalograph activity differs between normal control subjects and subjects suffering from tinnitus. Results indicated that male tinnitus patients as a group had a significantly reduced average total power as compared to control subjects. This finding contrasted with female(More)
