The role of frontal cortex-reticular interactions in performance and extinction of the classically conditioned nictitating membrane response in the rabbit
(Elsevier, 1982-06)
In order to investigate the behavioral role of interactions between frontal cortex and reticular nuclei, we examined the effects of single and combined lesions of these structures on the classically conditioned nictitating ...
Reproduction in wild female olive baboons
(Wiley Subscription Services, Inc., A Wiley Company, 1989)
The purpose of this paper is to evaluate several factors that influence female reproduction in a large troop of wild olive baboons ( Papio cynocephalus anubis ) based on 4 consecutive years of demographic data. Interbirth ...
The prediction of preference for unfamiliar urban places
(Kluwer Academic Publishers-Human Sciences Press; Human Sciences Press ; Springer Science+Business Media, 1982-03)
Preferences for unfamiliar urban environments were studied as a function of urban categories, viewing time, and four predictor variables: complexity, coherence, identifiability, and mystery. A nonmetric factor analysis of ...
Rod saturation in b-wave of the rat electroretinogram under two different anesthetics
(Elsevier, 1984)
B-wave increment threshold experiments in the rat show that "rod saturation" occurs at different background levels with different anesthetics. Rod saturation builds up over the first 60 sec of light adaptation in pentobarbital ...
Impact of urban nature: A theoretical analysis
(Elsevier, 1984-10)
The stresses and strains of the urban environment are widely acknowledged. The means for recovery, for recuperation, are perhaps less evident. In particular, the role of environmental configurations in this process is often ...
Chronic skull-anchored percutaneous implants in non-human primates
(Elsevier, 1989-09)
Three groups of chronic, skull-anchored, percutaneous implants differing in materials, design and surgical procedures used for implantation, were tested in macaque monkeys in conjunction with studies of an inner ear ...
Similarity of the discriminative stimulus effects of ketamine, cyclazocine, and dextrorphan in the pigeon
(Springer-Verlag, 1981-05)
Separate groups of pigeons were trained to discriminate the IM injection of ketamine, cyclazocine, or dextrorphan from saline. Each of the training drugs and phencyclidine produced dose-related, drug-appropriate responding ...
The rotational behavior model: asymmetry in the effects of unilateral 6-OHDA lesions of the substantia nigra in rats
(Elsevier, 1983-03-28)
A basic assumption of the `rotational behavior model' is that amphetamine (AMPH) produces ipsiversive rotational behavior in rats with unilateral 6-hydroxydopamine lesions of the nigrostriatal dopamine (DA) system. However, ...
Enduring changes in brain and behavior produced by chronic amphetamine administration: A review and evaluation of animal models of amphetamine psychosis
(Elsevier, 1986-06)
8. SummarySome people who repeatedly use stimulant drugs, such as amphetamine (AMPH), develop an AMPH-induced psychosis that is similar to paranoid schizophrenia. There has been, therefore, considerable interest in ...
A tail withdrawal procedure for assessing analgesic activity in rhesus monkeys
(Elsevier, 1986-06)
Rhesus monkeys were restrained in chairs from which their tails hung free so that their tails could be immersed into a thermos of water. Monkeys consistently kept their tails in 38-40[deg]C water for at least 20 sec, but ...
