Functional analysis of mutual behavior in laboratory rats (Rattus norvegicus).
Three pairs of rats were trained to synchronize their lever pressing according to a mutual reinforcement contingency, in which alternating lever presses that fell within a 500-ms window were reinforced with food. In Experiment 1, rats worked in adjacent chambers separated by a transparent barrier, and the effects of the mutual reinforcement contingency were compared with those under yoked-contr...
متن کاملReexamination of spectral mechanisms in the rat (Rattus norvegicus).
The spectral mechanisms of the rat were studied in electrophysiological and behavioral experiments. The photopic electroretinogram (ERG) was recorded (a) to rapidly flickering lights, (b) during the cone phase of dark adaptation, and (c) with a flicker photometric procedure. Each procedure indicated the presence of a single cone mechanism having a lambda max of about 510 nm. Increment-threshold...
متن کاملMilk availability modulates weaning in the Norway rat (Rattus norvegicus).
Two experiments were conducted to investigate the role of milk availability in the development of independent feeding and drinking in the Norway rat pup. Beginning on Day 14 postnatally, pups were exposed to different levels of milk supply by changing litter size from 8 to 4 versus 12 pups (Experiment 1) or limiting temporally the pups' access to a lactating dam to 8, 14, or 24 hr daily (Experi...
متن کاملStructure prediction and functional annotation of MHCII like hypothetical protein from laboratory rat (Rattus norvegicus)
The global diabetes epidemic has devastating personal and social effects in not only the developed countries but also in the developing countries especially in India. Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels that result from defects in insulin secretion or action, or both. Type 1 diabetes mellitus (T1DM) is usually a progressive autoi...
متن کاملUterine torsion in a Sprague Dawley rat (Rattus norvegicus).
Uterine torsion is a twisting of the uterus or uterine horn perpendicular to its long axis. We report a case of uterine torsion in an adult breeding Sprague Dawley rat. The rat died a month after her last recorded delivery. Post mortem examination of the rat revealed 270 degrees torsion of the right uterine horn. The uterus contained a single foetus. The liver was pale and enlarged. The rest of...
