Mechanisms of light adaptation in rat retina
(Elsevier, 1982)
Green, Dowling, Siegel and Ripps (1975) J. gen. Physiol. 65, 483-502 found that both receptors and post-receptoral elements regulate the process of light adaptation in skate retina. As a test of the generality of this ...
Spatial attentional shifts: Implications for the role of polysensory mechanisms
(Elsevier, 1988)
Simple reaction times to lateralized visual (Experiment 1) or auditory (Experiment 2) targets were studied in normal subjects. The targets were preceded by a visual or auditory cue located on the same (valid cue), or ...
Enduring changes in brain and behavior produced by chronic amphetamine administration: A review and evaluation of animal models of amphetamine psychosis
(Elsevier, 1986-06)
Some 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 characterizing ...
Persistent sensitization of dopamine neurotransmission in ventral striatum (nucleus accumbens) produced by prior experience with (+)-amphetamine: a microdialysis study in freely moving rats
(Elsevier, 1988-10-18)
In humans the repeated use of amphetamine (AMPH) produces a hypersensitivity to the psychotogenic effects of AMPH that persists for months to years after the cessation of drug use. To explore the neurobiological basis of ...
Impairments in visual discrimination performance and gaze shifts in monkeys with superior colliculus lesions
(Elsevier, 1980-08-25)
Eye movements of monkeys were recorded while they performed a visual discrimination task before and after superior colliculus (SC) lesions or control surgery. The monkeys with SC lesions were impaired in orienting their ...
Cortical noradrenaline depletion eliminates sparing of spatial learning after neonatal frontal cortex damage in the rat
(Elsevier, 1982-10-08)
The possibility that cortical noradrenaline (NA) is necessary for the sparing of function that occurs after neonatal frontal cortex damage was examined. Spatial localization by rats with frontal cortex damage sustained ...
Sex differences in the effects of early experience on the development of behavioral and brain asymmetries in rats
(Elsevier, 1984-09)
The influence of early experience (preweaning handling) on the development of several postural/motor asymmetries (side bias in an open field, turn preference in a T-maze, amphetamine-induced rotational behavior, tail ...
Feline subthalamic nucleus neurons contain glutamate-like but not GABA-like or glycine-like immunoreactivity
(Elsevier, 1989-07-03)
The identity of the neurotransmitter of subthalamic nucleus neurons has not been definitely established. GABA, glycine, and glutamate have all been hypothesized to be the neurotransmitter of these neurons. Immunohistochemistry ...
The long-term effects of repeated amphetamine treatment in vivo on amphetamine, KCl and electrical stimulation evoked striatal dopamine release in vitro
(Elsevier, 1988)
Exposure to amphetamine (AMPH) in vivo produces an enduring enhancement (`sensitization') in AMPH-stimulated striatal DA release in vitro. Experiments were conducted to determine whether striatal DA release evoked by ...
Onchocerca volvulus heat shock protein 70 is a major immunogen in amicrofilaremic individuals from a filariasis-endemic area
(Elsevier, 1989-03-15)
Infestation with organisms causing lymphatic filariasis (i.e. Wuchereria bancrofti and Brugia malayi) results in a variety of clinical presentations. It is possible that some of the variation is due to differences in host ...
