| strain_characteristics |
Compared with MNR, the strain has a high open-field defecation, low ambulation, low rearing, low shock avoidance conditionability and tends to be more emotional in a wide range of behaviour (Broadhurst 1975), and have a higher preference for ethanol (Brewster 1968). Also differs from MNR in norepinephrine concentration in hypothalamus, heart, spleen and adrenal glands, suggesting that the sympathetic system might be functionally related to behavioural differences between the strains (Liang and Blizzard 1978). Lower specific benzodiazepine binding than MNR in hippocampus, hypothalamus, midbrain, medulla/pons and spinal cord, which might be a biological basis for differences in emotional behaviour (Robertson et al 1978). Long emergence latency in a novel environment in females (12/12) and also into a familiar environment in males (11/12) (Harrington 1971a). High open field defecation (1/12 males 2/12 females) (Harrington 1972). Shows substantial habituation to acoustic startle stimulous (Commissaris et al 1988). mRNA and protein populations in the brains of MR and MNR have been studied by Whatley et al (1992). Good breeding performance (4/12) and large litter size (2/12) (Hansen et al 1973). See also MNR. |
