Neurology Exam by Howard F. Stein

Neurology Exam

My neurologist asks me many questions
To make sense of my brain:
       What day of the week is it?
       Where are you now?
       What is your home address?

              (What if I am homeless?)
       What state are you in?
       Where were you born?
       What did you eat this morning?
       How many fingers am I holding up?

I answer them all
With confidence and precision.
Perfect score – far better than in
Other realms of my life.

I break the brief silence
With hesitant questions of my own:
       Tell me, doctor, with all
       Your education and medical experience,
       So what even if all my answers are correct?
       Today, Thursday, March 10,
       Is neither more nor less than
       Tuesday, August 23
       Or any other date of the year.
       Our Earth is merely at different
       Points in its orbit around the sun.

Despairing, I press her further:
       As you search for what
       My answers can tell you
       About the workings of my brain,
       Your questions are not wrong –
       Only beside the point
       In the face of my urgency.

       Tell me, why do you live?
       Why do you wish to awaken
       The next day?

       What is or is not inside my skull
       And nervous system
       Cannot answer questions
       Like these.
       I do not live for the sake
       Of how much white matter
       Remains in my brain.

       Only loving and being loved
       Can calm the unrest
       My questions float upon.
       Without their balm,
       I do not care
       When or where I am,
       What I ate earlier today,
       Or whether I can tell you
       How many fingers
       You hold up before my face.

Author’s Note: Distinction between white and gray matter of the brain:
The white matter of your brain and spinal cord is composed of bundles of axons. These axons are coated with myelin, a mixture of proteins and lipids, that helps conduct nerve signals and protect the axons. White matter’s job is to conduct, process, and send nerve signals up and down the spinal cord.
       Gray matter, named for its pinkish-gray color, is home to neural cell bodies, axon terminals, and dendrites, as well as all nerve synapses. This brain tissue is abundant in the cerebellum, cerebrum, and brain stem. It also forms a butterfly-shaped portion of the central spinal cord.
The back portion of this butterfly shape is known as the posterior, sometimes called the dorsal gray horn. This region passes sensory information via ascending nerve signals to the brain. The front part, which is sometimes called the ventral gray horn, sends descending nerve signals governing motor activities to your autonomic nerves.
