Spatial attentional shifts: Further evidence for the role of polysensory mechanisms using visual and tactile stimuli
(Elsevier, 1989)
Normal subjects performed simple reaction time responses to lateralized visual target stimuli (Experiment 1) and lateralized tactile target stimuli (Experiment 2). In each experiment, the lateralized targets were preceded ...
Localization of neurons containing pro-opiomelanocortin-related peptides in the hypothalamus and midbrain of the lizard, Anolis carolinensis evidence for region-specific processing of [beta]-endorphin
(Elsevier, 1984-12-24)
Immunohistochemical analyses of the lizard brain, following colchicine pretreatment, revealed two populations of POMC-producing cell bodies located in medial-basal hypothalamus and the mesencephalic tegmentum. Analyses of ...
Multiple steroid hormone levels in depressed patients and normal controls before and after exogenous ACTH
(Elsevier, 1991)
Forty depressed patients and 36 age- and sex-matched controls were given 250 [mu]g ACTH1-24 by bolus. Plasma steroid hormone levels were measured prior to and 60 min after ACTH administration. The depressed patients had ...
Phobic anxiety does not affect plasma levels of thyroid stimulating hormone in man
(Elsevier, 1982)
(1) The effect of anxiety on plasma levels of thyroid stimulating hormone (TSH) is not clear, despite a number of relevant studies. (2) Nine human subjects with severe phobias had blood samples taken for TSH assay every ...
Pharmacological and anatomical evidence of selective [mu], [delta], and [chi] opioid receptor binding in rat brain
(Elsevier, 1986-12-03)
While the distribution of opioid receptors can be differentiated in the rat central nervous system, their precise localization has remained controversial, due, in part, to the previous lack of selective ligands and insensitive ...
Antidepressant withdrawal-induced activation (hypomania and mania): Mechanism and theoretical significance
(Elsevier, 1984-03)
Electrocortical and behavioral arousal are separate phenomena subserved by different neural substrata operating in parallel. A comprehensive theory of `activation' must take into account the relationships between the ...
Endocrine and physiological changes during "spontaneous" panic attacks
(Elsevier, 1987)
Eight patients with DSM-III-defined panic attacks were compared to four normal subjects on hormonal and physiological variables measured at six predetermined times through 24 hr and also during nine "spontaneous" attacks. ...
Characterization of the forms of [beta]-endorphin and [alpha]-MSH in the caudal medulla of the rat and guinea pig
(Elsevier, 1986-07-09)
The post-translational processing of pro-opiomelanocortin (POMC) in brain remains controversial. Classically, there was thought to be a single cell group in the arcuate nucleus with long projections through limbic structures. ...
Neuroregulatory effects of nicotine
(Elsevier, 1989)
The impact of nicotine on the central nervous system is, in an important sense, neuroregulatory, with cascading effects on physiological and biochemical function as well as on behavioral activity. Accordingly, the ...
Assessment of muscarinic receptor concentrations in aging and Alzheimer disease with [ 11 C]NMPB and PET
(John Wiley & Sons, Inc., 2001-03-15)
Cerebral cholinergic deficits have been described in Alzheimer disease (AD) and as a result of normal aging. At the present time, there are very limited options for the quantification of cholinergic receptors with in vivo ...
