One of the most important effects to control against in psychological experimentation is the effect of experimenter bias. Experimenters can all too easily find what they are looking for (support for their own hypotheses) by inadvertently influencing the way in which their subjects behave.

Four months of sigmoid colon intrinsic denervation of young male Wistar rats resulted in typical megacolon. Average 46.0% denervation of the Auerbach plexus was obtained by serosal application of benzalkonium chloride (0.2% v/v). Denervation was assessed by ganglion cell counts in a 480-nm extension of the treated segment.

Basic mechanisms of the rat ERG were reinvestigated with contemporary methods of recording and photic stimulation via an optic fiber system connected with a contact lens. Flash stimulation and background illuminance were performed with photometrically defined light stimuli.

Veterinary Clinics of North America: Exotic Animal Practice, 2010
The past decade has seen an increase in the number of rodents being kept as pets and subsequently in the number of rodent owners seeking veterinary services. The common rat, (Rattus norvegicus) has become increasingly popular, particularly as novel varieties have been introduced to the pet market.

We report three tumours arising in the brain stem or adjacent cranial nerves of the Alderly Park rat. Light microscopy with special stains, immunocytochemistry and electron microscopy supported the conclusion that both neuronal and myoid differentiation occurred in all neoplasms.

SUMMARY Glaucoma in the rat is described. In Wistar rats buphthalmus was diagnosed. In strains of Sprague–Dawley rats the glaucomas were considered to be secondary, however, the causes were not easily determined. One case was associated with a tumour of the ciliary body; the others were in the main associated with intraocular inflammatory disease of ...
