True about cerebelluma) Cerebral cortex have mostly inhibitory effectsb) Co-ordinationc) Planning of motor movementsd) Excitatory effect from deep nuclei: (A) abc, (B) abd, (C) acd, (D) bcd
Answer is D. 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.
