Five lobes of the brain have we evolved
All doing different jobs but all intervolved.
And all these lobes, just mm thick
But still so unique and they do the trick.
This layer, as thin as can be
Cell bodies, gray matter in both you and me.
All the lobes does a number of things
And to the table each will bring
Some special function not shared at all
And each function is nothing small.
The frontal lobe deals with movement
Having fun or paying the rent.
Anterior to the central sulcus
The primary motor cortex, homunculus.
And on it the body pattern distorted
With motor efferent numbers reported.
On the opposite end is the occipital lobe
And for magazines is the vogue.
For vision here is processed such
That colors we see are so much
Trichromatic we’re called because we see three
Blue, green and red, the cones we can see.
The temporal lobe is on the side
And its importance we will not slide.
The auditory cortex on this region
Has a map of each audition.
Different frequencies along a line
That allow our hearing to be sublime.
And this tonotopic map, just to make it more fun,
Is exactly the same in everyone.
Olfaction is also found on this part
The last stop for smell, quite far from the start.
The only sense that isn’t modified
And gets to the brain without being tried.
Under the temporal hidden from view
A lobe of importance you should not skew.
It is the center for pain and taste.
Life without flavor, what a waste.
And of course pain, not to be ignored
Never builds up, never gets ignored.
Last the parietal, a very odd place
The association cortex coordinating space.
This is where you first perceive touch
And the ability you have is much.
The sensory afferents that lead there
All must need to share
The area behind the sulcus central
Allows you to feel your dog, your best pal.
And the homunculus there functions the same
But this one has sensory function for fame.
Sensory afferents taking up space
So you can have feelings all over your face.
