The facial nerve is the seventh cranial nerve, or simply cranial nerve VII.

It's called Trans Cranial Magnetic Stimulation, or TMS.

Typically, the exam tests mental status, function of the cranial nerves (including vision), strength, coordination, reflexes, and sensation.

Cranial and caudal neuropores become progressively smaller until they close completely (by day 26) forming the neural tube.

Its diameter increases from about 1.6 mm within the eye to 3.5 mm in the orbit to 4.5 mm within the cranial space.

Then the brain's connection to the cranial nerves and spinal cord are severed, and the brain is lifted out of the skull for further examination.

The vestibulocochlear nerve (auditory vestibular nerve), known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain.

The trochlear nerve (the fourth cranial nerve) is a motor nerve (a somatic efferent nerve) that innervates a single muscle the superior oblique muscle of the eye.

We formed a company called NeuroPace and we started work on responsive neurostimulation, and this is a picture of what the device looked like, that's placed into the cranial bone.
