MGI - Inbred Strains: TMD

Inbred Strains of Rats: TMD

TMD

Inbr. F20+.

Colour: Black.

Genet. a.

Origin: PL Broadhurst from stock selected by Tryon for poor maze learning performance. Although TMD and TS3 are derived from the same outbred stock, they were inbred independently and should be regarded as different inbred strains (Festing 1979b).

Characteristics

Low voluntary alcohol acceptance concentration (1/4) (Russell and Stern 1973 , see also Amit and Smith, 1992). Low shock avoidance (7/8) (Rick and Fulker 1972). High brain GABA (3/8) (Rick et al 1971).
