Morphine alters the structure of neurons in the nucleus accumbens and neocortex of rats
(John Wiley & Sons, Inc., 1999-08)
Rats were given repeated injections of 10 mg/kg of morphine and were then left undisturbed for 24–25 days before their brains were processed for Golgi-Cox staining. Prior exposure to morphine decreased the complexity of ...
Evidence for a power law intensity code in the coupled cones of the turtle
(Elsevier, 1990)
The hyperpolarizing responses to light were recorded intracellularly from red cones of the turtle, Pseudemys scripta elegans. Pairs of slit stimuli were flashed alone or together at various intensities, one slit positioned ...
Unilateral striatal lesions in the cat disrupt well-learned motor plans in a GO/NO-GO reaching task
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-03)
We examined the changes in learned and spontaneous motor behavior after a unilateral excitotoxin lesion of the neostriatum. Cats were trained to perform a sensory-cued GO/NO-GO reaching task. Success rate, reaction time, ...
Depression and neuropsychological test peformance in acute spinal cord injury patients: Lack of correlation
(Elsevier, 1990)
Factors which have been causally related to neuropsychological deficits in acute spinal cord injury (SCI) patients include advanced age, limited educational level, acute traumatic brain injury, alcohol and/or substance ...
Kidney and Retinal Defects (Krd), a Transgene-Induced Mutation with a Deletion of Mouse Chromosome 19 That Includes the Pax2 Locus
(Elsevier, 1994-09-15)
The semidominant mutation Krd (kidney and retinal defects) was identified in transgenic line Tg8052. Krd/+ mice have a high incidence of kidney defects including aplastic, hypoplastic, and cystic kidneys. Retinal defects ...
Primate basal ganglia activity in a precued reaching task: preparation for movement
(Springer-Verlag, 1993-07)
Single cell activity was recorded from the primate putamen, caudate nucleus, and globus pallidus during a precued reaching movement task. Two monkeys were trained to touch one of several target knobs mounted in front of ...
Cortex, striatum and cerebellum: control of serial order in a grooming sequence
(Springer-Verlag; Springer-verlag, 1992-08)
Rats emit grooming actions in sequences that follow characteristic patterns of serial order. One of these patterns, a syntactic chain, has a particularly stereotyped order that recurs spontaneously during grooming thousands ...
Square root intensity coding in turtle cones: Physiological mechanisms
(Elsevier, 1990)
The effect of coupling on the intensity-response functions for full field and for slit stimuli was studied by comparing the shapes of the curves obtained from several strongly coupled red cones of turtle with that of one ...
Auditory cues and inhibition of return: the importance of oculomotor activation
(Springer-Verlag, 1996-11)
We studied the effects of eccentric auditory cues to clarify the conditions that evoke inhibition of return (IOR). We found that auditory cues positioned 12° to the left or right of midline failed to produce IOR whereas ...
The effects of methamphetamine and cocaine on motor behavior and extracellular dopamine in the ventral striatum of Lewis versus Fischer 344 rats
(Elsevier, 1994-12-30)
The effects of an acute systemic injection of methamphetamine (mAMP) or cocaine (COC) on motor behavior (stereotypy, locomotor activity, and rearing) and extracellular dopamine (DA) in the ventral striatum were compared ...
