WebProjection fibers connect the cerebral cortex to the brainstem and spinal cord. These fiber tracts help to relay motor and sensory signals between the central nervous system and peripheral nervous system. What do projection neurons do? In the neocortex, projection neurons are excitatory neurons that send axons to distant brain targets. WebInstead, fibers that travel down from the cortex (i.e. corticopontine fibers) synapse on a variety of nuclei here called pontine nuclei. Then, groups of fibers project from the pontine nuclei on one side of the pons, cross to the other side of the pons, and come together to form the middle cerebellar peduncles. The middle cerebellar peduncles ...
