Introduction to Brain, Techniques, & Names NBIO 401 Robinson
Objectives: -Be able to use correctly, and immediately, understand the basic terms describing direction and structures within the CNS. -Be able to describe what information each stain and technique can provide. -Be able to describe the major divisions of the CNS and generally describe their relationship in developing and adult brain.

Inputs to Cell Bodies/Dendrites inputs afferents synapse onto Axon Course tracts fibers funiculus fasciculus lemniscus project run (directional descriptors often attached) Outputs from Axons outputs efferents terminal field terminate/end synapse onto Neuron Cell Bodies nucleus ganglion originate relay

Cell bodies: red nucleus Synapses: cerebellar inputs Axons: rubrospinal tract decussates (crosses the midline), and descends, to terminate on neurons in the spinal cord. Thus, we say that the red nucleus projects to the spinal cord.
