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, ...
Cellular expression of Midkine-a and Midkine-b during retinal development and photoreceptor regeneration in zebrafish
(Wiley Subscription Services, Inc., A Wiley Company, 2009-05-01)
In the retina of adult teleosts, stem cells are sustained in two specialized niches: the ciliary marginal zone (CMZ) and the microenvironment surrounding adult MÜller glia. Recently, MÜller glia were identified as the ...
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 ...
Convergence, divergence, pupillary reactions and accommodation of the eyes from faradic stimulation of the macaque brain Accepted in part fulfillment of the requirements for the degree of Doctor of Philosophy at the University of Michigan. Funds for technical help were provided by U. S. Public Health Service grant B-1442. The author wishes to express his appreciation to Parke, Davis and Company for aid in carrying on this reaserch.

Invasive squamous carcinoma of the vulva in young patients
(Elsevier, 1982-04)
Over a 30-year period, 17 patients below the age of 35 with invasive squamous carcinoma of the vulva were identified, 8 of whom (47.1%) had "microinvasive" disease. Venereal diseases and condyloma accuminata were not ...
Imaging Changes after Stereotactic Radiosurgery of Primary and Secondary Malignant Brain Tumors
(Kluwer Academic Publishers; Springer Science+Business Media, 2002-01)
After radiosurgery of malignant tumors, it can be difficult to discriminate between transient treatment effects, radiation necrosis, and tumor progression on post-treatment imaging. Misinterpretation of an enlarging lesion ...
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 ...
Effect of Neuropeptide Y on Natural Killer Activity of Normal Human Lymphocytes
(Elsevier, 1993-03)
The in vitro effect of neuropeptide Y (NPY) on natural killer (NK) cell activities of normal lymphocytes was investigated. NPY at 10-9 to 10-12M concentrations produced significant suppression of NK activity against K 562 ...
Functional characterization of mouse α4β2 nicotinic acetylcholine receptors stably expressed in HEK293T cells
(Blackwell Science Ltd, 2004-12)
Mouse α4β2 nicotinic acetylcholine receptors (nAchRs) were stably expressed in HEK293T cells. The function of this stable cell line, termed mmα4β2, was assessed using an aequorin-based luminescence method that measures ...
Comparison of the distribution of Na+, K+-ATPase and myelin-associated glycoprotein (MAG) in the optic nerve, spinal cord and trigeminal ganglion of shiverer (shi/shi) and control (+/+) mice
(Elsevier, 1987-07-07)
Na+,K+ATPase and myelin-associated glycoprotein (MAG) were studied by immunocytochemistry on paraffin sections of the spinal cord, optic nerve and trigeminal ganglion of adult control (+/+) and CNS myelin-deficient shiverer ...
