Today, I have some neuroanatomy for you: prefrontal cortex.
Mmmm…goes down smooth.
What is a prefrontal cortex (PFC)? This is an area of your cerebral cortex located in the frontal lobe that carries out what neuroscientists will often refer to as “executive functions.” These include mood and action regulation, working memory, attention, etc.
Let’s discuss action regulation. Have you ever had a thought you didn’t want to have, or perhaps were not so bothered by having, but simply would never act upon? That’s because your PFC shuts down your urges. It makes sense then that reductions in prefrontal volume, as well as low connectivity of the PFC with other brain regions has been seen in criminal populations. Some people simply have a reduced capacity not to do bad things. Causes of this include life stressors, lead poisoning and cancer. (more…)
