My Ten Per Cent


Write a new post in response to today’s one-word prompt.


You’ve all heard that most of us use only 10% of our brain’s capacity. What that means to me is that, after 69 years, 90% of my brain is full of information I don’t know I know.

So where is my useful ten per cent?  I know it’s not in my olfactory cortex, since I’ve pretty much lost my sense of smell. Boy, is that a bummer.

Look, the brain doesn’t have much depth compared to other pars of the body, so it shouldn’t be too hard to figure where my active 10% lies.  Right?  Right.

My auditory cortex and my visual cortex are definitely not functioning at 100%, so it must be something else.  I find myself losing my balance a little bit now and then, so it must not be the motor cortex. The central sulcus is really a fissure that defines the lobes of the brain, but I don’t think it has much to do with intelligence or learning.  It acts as a good roadmap for neurosurgery, though, so I hope those doctors are paying close attention to the map.

The temporal lobes?  They’re responsible for hearing, memory, meaning, and language. They also play a role in emotion and learning. The temporal lobes are concerned with interpreting and processing auditory stimuli.Those seem to be in pretty good shape except for the auditory part, so maybe they contribute to the ten per cent.

Wait. I think I found it!  The gustatory cortex, of course!  It helps detect flavor!  Food!  Chocolate!  Coffee!  Bacon!  Yay, gustatorycortex!  I’m sure it’s an important part of my 10 per cent, and it’s buried in the depths of my brain, so I’m hoping it will never die off until I do 🙂
