Six pairs of female squirrel monkeys were given a daily intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) for 9-14 days, beginning the same day on which they received either a bilateral 6-hydroxydopamine lesion or a sham lesion of the locus coeruleus. Sham animals developed typical parkinsonian signs (i.e. tremor, bradykinesia, hypokinesia and reduced blink rate) which largely recovered by six to nine weeks after the start of MPTP treatment. At nine weeks, post… CONTINUE READING
