The science to scan brain activity is currently in its infancy. Brain scans track blood flow; that does not mean specific functions are limited to that region.
Humans believe they are separate from the environment, which is a wrong presumption.
Environmental and climate change and its imminent effects on humans are proof that we are not separate or insulated from our surroundings.

Complex cycles and systems operate in the brain. The Glymphatic (or Glial Lymphatic) system, discovered recently, takes care of the brain waste much like a complex sewer system.
The system is only active when one is asleep, and it clears our brain of all neurotoxic substances that have collected during the day.

The brain loves to identify, tag, or label all the feelings and emotions that are being experienced.
