intensity and duration of motor effects after injection of carbachol ( 30 mug/3 mul bilateral ) into different brain areas were found to depend on localization : strongest tremor was elicited by injections into the nucleus caudatoputamen and cortex cerebri , moderate tremor by administration into the substantia nigra reticularis , globus pallidus and thalamic brain regions .
