20 microgram TRH injected bilaterally into the caudate-putamen, tuberculum olfactorium, nucleus accumbens, amygdala, lateral ventricles, midbrain or cerebral cortex failed to induce any increase in locomotor activity (measured using photocells), although other behavioural changes were observed after each injection, and included body shakes, limb tremor, repetitive head and limb movements, biting, scratching and an alert appearance.
