β-funaltrexamine antagonizes the discriminative stimulus effects of morphine but not naltrexone in pigeons
(Springer-Verlag, 1987-02)
Antagonistic actions of the irreversible, μ-selective antagonist β-funaltrexamine (β-FNA) were evaluated in pigeons trained to discriminate among intramuscular injections of morphine (5.6 mg/kg), saline, and naltrexone ...
Generation of theta rhythm in medial entorhinal cortex of freely moving rats
(Elsevier, 1980-05-05)
A regular slow wave theta rhythm can be recorded in the medial entorhinal cortex (MEC) of freely moving rats during voluntary behaviors and paradoxical sleep. Electrode penetrations normal to the cortical layers proceeding ...
Inhibition of Vesicular Glutamate Uptake by Rose Bengal-Related Compounds: Structure–Activity Relationship
(Kluwer Academic Publishers-Plenum Publishers; Springer Science+Business Media, Inc., 2005-03)
Synaptic vesicular accumulation of glutamate is a vital initial step in glutamate transmission. We have previously shown that Rose Bengal, a polyhalogenated fluorescein analog, is a potent inhibitor of glutamate uptake ...
Stress induced grooming in the rat -- An endorphin mediated syndrome
(Elsevier, 1979-07)
Exposure of adult male Sprague--Dawley rats to a non-traumatic noise-light stress procedure subsequently increased grooming behavior in a novel environment. The grooming syndrome was marginally facilitated by adrenalectomy ...
Inhibition-mediating dopamine receptors and the control of intracranial reward
(Springer-Verlag, 1979-01)
A receptor selective agonist and antagonist of inhibition-mediating dopamine receptors (type II receptors) produced significant and dose-related alterations in bar-pressing for intracranial reward. Receptor inhibition by ...
A VIP-like peptide co-occurs with substance P and enkephalin in cholinergic preganglionic terminals of the avian ciliary ganglion
(Elsevier, 1987-07-09)
Using single-label and double-label immunohistochemical techniques, many of the substance P-enkephalin containing preganglionic terminals of the avian ciliary ganglion were found to also contain a VIP-like peptide. Since ...
The effect of limbic damage on the retention and performance of a runway response
(Elsevier, 1966-07)
Rats were trained to run a linear runway while hungry for food. Then they were tested for retention, continued performance levels, and extinction after recovery from bilateral damage of the hippocampus, the septal area, ...
The temporal structure of motivation: III. Identification and ecological significance of ultradian rhythms of intracranial reinforcement
(Elsevier, 1980-10)
Adult male Sprague-Dawley rats were stereotactically implanted with intracranial electrodes aimed at the anterior medial forebrain bundle, and trained to self-administer intracranial stimulation. Following 3 weeks of ...
Response characteristics of lamb trigeminal neurons to stimulation of the oral cavity and epiglottis with different sensory modalities
(Elsevier, 1989-05)
A region of the trigeminal complex located at the border of the subnucleus interpolaris and subnucleus caudalis receives not only trigeminal nerve inputs from the face, tongue and palate, but also afferent terminations ...
