Bilateral ischemia has been shown to alter the net brain levels of energy metabolites such as ATP, phosphocreatine, glucose, and glycogen. The amino acid neurotransmitter gamma-aminobutyric acid (GABA) exerts a tonic inhibitory influence on neural activity. The present studies were designed to evaluate the influence of elevated GABA levels on the metabolic(More)
RATIONALE Two rat auditory evoked potential (AEP) components P13 and N40 are suggested as analogues to the human P50, which has abnormal suppression properties in schizophrenia. However, P50 likely reflects neural activity from several different brain areas. Studies examining each of these components in the rat model have proposed circuitry that involves(More)
A comparison was made of human postmortem muscarinic-cholinergic, beta-adrenergic and serotonergic (presynaptic) recognition sites in cortical tissues derived from suicide and homicide (control) victims. An elevation of 47% and 35% in the suicide group compared to controls was observed in receptor ligand binding for 3H-quinuclidinyl benzilate (QNB,(More)
Fifty-one compressed distorted cervical articular masses were found in 29 patients seen at this institution over a nine-month period. The significance of these findings is discussed and it is concluded that in most instances these represented compression fractures with deformity of the articular process. Selected signs suggestive of a compressed articular(More)
A 1.8-kilobase (kb) cDNA clone for a beta 1 subunit of the human gamma-aminobutyric acidA (GABAA) receptor has been isolated and sequenced. The longest open reading frame of the clone, pCLL610, contains nucleotide sequence encoding a portion of the putative signal sequence followed by 449 amino acids of the entire mature protein. The deduced amino acid(More)
The relationship between rapid eye movement sleep deprivation (REMD) and rat beta-adrenergic receptors was evaluated. REMD was achieved using the platform method and verified by EEG and EMG recordings. Although the amount of REM sleep was diminished 90%, there was no alteration in either the number of binding sites or their affinity for(More)
