Ornithine decarboxylase activity in retinal explants of goldfish undergoing optic nerve regeneration
(Elsevier, 1981-06)
Retinal explants cultured in the presence of fetal calf serum (FCS) exhibit an increase in the activity of ornithine decarboxylase which is maximal several hours after explanation. The measured activity of this enzyme is ...
Activity disc and cage for continuous measurement of running activity and core temperature in hamsters
(Elsevier, 1991-11)
We describe a design for the modular horizontal activity disc and tandem cages suitable for continuous monitoring of spontaneous running and of core tempertaures in golden hamsters. An acrylic disc is equipped with a short ...
Tail pinch induced stress-arousal facilitates brain stimulation reward
(Elsevier, 1979-01)
Adult male Sprague Dawley rats with chronic access to self stimulation were subjected to handling, tail pinch, or left undisturbed. Tail pinch increased responding for positive reinforcement while the other conditions did ...
Electron microscopic demonstration of horseradish peroxidase-tetramethylbenzidine reaction product as a method for identifying sensory nerve fibers in the rat tooth pulp
(Elsevier, 1983-11-11)
The purpose of the present investigation was to determine if the horseradish peroxidase could be used as a method for labeling sensory nerve fibers (specifically, tooth pulp afferents) for detailed ultrastructural analyses. ...
Mating behavior induces selective expression of Fos protein within the chemosensory pathways of the male Syrian hamster brain
(Elsevier, 1992-08-31)
The effect of mating behavior on the expression of Fos protein was analyzed within the chemosensory pathways of the male Syrian hamster brain. Following a single mating test, the number of Fos-immunoreactive (Fos-ir) neurons ...
Unilateral substantia nigra lesions and schedule-induced polydipsia
(Elsevier, 1986)
The present experiment investigated the effects of unilateral 6-hydroxydopamine lesions of the substantia nigra (SN) on schedule-induced polydipsia (SIP). Lesions were made in either the "dominant" or "non-dominant" ...
Animal models and human depressive disorders
(Elsevier, 1981)
Clinical depressive disorders are complex in presentation, dissimilar in origins and course, and often pleomorphic in character. An adequate understanding of their origins, biological substrates, and amenability to established ...
Chronic drug infusion into the scala tympani of the guinea pig cochlea
(Elsevier, 1992)
This research describes a unique, effective and inexpensive delivery system to provide discrete quantities of drugs on a chronic basis to the inner ear. The amount of the drug administered and specific timing of each ...
Effect of altered sensory conditions on multivariate descriptors of human postural sway
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
Multivariate descriptors of sway were used to test whether altered sensory conditions result not only in changes in amount of sway but also in postural coordination. Eigenvalues and directions of eigenvectors of the ...
Developmental changes in taste responses from glossopharyngeal nerve in sheep and comparisons with chorda tympani responses
(Elsevier, 1983-12)
To learn whether there are developmental changes in salt and acid taste responses from the posterior tongue, we recorded from the glossopharyngeal nerve, which innervates taste buds in circumvallate papillae, in sheep ...
