Ipsilateral or Contralateral? A: Ipsilateral Q: Where do the Pontine Nuclei receive information from? A: Cortex Q: Where do the Pontine Nuclei project its info? Thru what? A: Projects info to the Cerebellum thru the middle cerebellar peduncle Q: What happens if you have a lesion to the pontine nuclei? A: Also lesion CST -> Conttralateral UMN, spastic paralysis Pontine Nuclei -> just a tremor
