spinal cord
You are the corpus callosum, the bundle of nerve fibers that connects the left and right hemispheres of the brain.
The internal capsule and the cerebral peduncles are white matter tracts that connect the cerebrum to lower brain areas such as the brainstem. These pathways are important for transmitting signals between different regions of the brain.
Brainstem
The reticular formation is a network of neurons located in the brainstem. It is involved in regulating arousal, attention, and sleep-wake cycles.
No, the brainstem is down low, like the stem of a flower.

spinal cord
The brainstem sits between large organs -- the brain (including cerebrum and cerebellum) and spinal cord -- and is directly connected to them. The three segments of the brainstem (the midbrain, pons, and medulla) also give rise to most of the twelve cranial nerves (excluding cranial nerves I, II, and arguably XI).
The brainstem is the most inferior portion of the brain.
A very sharp knife.
