You are... The Cingulate Gyrus!!!
Snugly encircling the superior thalamus, and sitting atop the corpus callosum,
you are an integral part of the limbic system.
You remain a mystery, but common thought is that your reciprocal connections
to the frontal cortex and limbic system link decision-making and emotion!
Although you are mushy in consistency, you are a great friend to those around you
and your word is as solid as oak. You detest it when
people prod you, so you do need to lighten up a bit.
All in all, though, you are a solid citizen.
(And without you, people often find themselves unable to talk or move!)
