Long-lasting changes in morphine sensitivity following amygdaloid kindling in mice
(Elsevier, 1981-12)
Mice tested at either 3, 27 or 90 days following their last amygdala kindled convulsion exhibited a marked increase in response to morphine compared to controls. Kindled animals showed a higher incidence of clonic convulsions ...
Relation between eating evoked by lateral hypothalamic stimulation and tail pinch in different rat strains
(Elsevier, 1982-03)
The similarity between the behaviors evoked by tail pinch (TP) and electrical stimulation of the lateral hypothalamus (ESLH) has been noted by many investigators. Evidence is presented for a possible inverse relationship ...
Intraventricular microdialysis: a new method for determining monoamine metabolite concentrations in the cerebrospinal fluid of freely moving rats
(Elsevier, 1988-06)
A new method is described to estimate the cerebrospinal fluid (CSF) concentrations of monoamine metabolites (dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA)) in the lateral ...
Sensitization of rotational behavior produced by a single exposure to cocaine
(Elsevier, 1985-05)
In rats with a unilateral 6-OHDA lesion of the substantia nigra a single exposure to cocaine significantly enhanced the ipsiversive rotational behavior produced by a second injection given one week later. It is concluded ...
A simple in vitro technique to measure the release of endogenous dopamine and dihydroxyphenylacetic acid from striatal tissue using high performance liquid chromatography with electrochemical detection
(Elsevier, 1984-05)
An easily constructed, inexpensive and simple system is described for the superfusion of neural tissue. To characterize the system, the dynamics of endogenous dopamine and dihydroxyphenylacetic acid release from striatal ...
Discriminative stimulus effects of etorphine in rhesus monkeys
(Springer-Verlag, 1981-03)
Two rhesus monkeys were trained to discriminate the IM injection of etorphine (0.001 mg/kg) from saline in a task in which 20 consecutive responses on one of two levers resulted in food delivery. In both monkeys, etorphine ...
Sex differences and estrous cycle dependent variation in rotational behavior elicited by electrical stimulation of the mesostriatal dopamine system
(Elsevier, 1982-11)
In this study electrical stimulation-induced rotational behavior was used as a behavioral index of mesostriatal dopamine (DA) activity to investigate gender and hormonal influences on the DA system. In female rats we found ...
A microdrive positioning adapter for chronic single unit recording
(Elsevier, 1988)
A new micropositioner design for use in chronic, transdural single unit recording studies is presented. The adapter is used to position an electrode microdrive assembly to any desired location within a surgically implanted ...
Hippocampal rhythmic slow activity (RSA, theta): A critical analysis of selected studies and discussion of possible species-differences
(Elsevier, 1980)
The literature concerning the correlates of hippocampal RSA (theta) has seen a wealth of hypotheses generated from seemingly contradictory data. Two possible reasons for this are examined here. (1) An analysis of the maximum ...
