<prompt> True about cerebelluma Cerebral cortex have mostly inhibitory effectsb Co-ordinationc Planning of motor movementsd Excitatory effect from deep nucleiabcabdacdbcd  <response>: Cerebral cortex effects on cerebellum are all excitatory. Co-ordination is through spinocerebellum. Planning and programming of voluntary movements is through neo cerebellum. Deep nuclei outputs are always excitatory.
