Nervous System 101: Development, Autonomic Regulation and the Ceptions

Development: Efficiency is the goal. In Utero, the brain prepares more pathways (synapses) than it needs. After birth, as we learn and develop unused pathways are retired with efficiency as the goal. Our body is always sending messages, neurons, through myelinated nerve fibers to the dorsal root ganglia, where those messages are deciphered by the parts of our brain.

Unconscious Neurological Input: Autonomic Regulation

Proprioception: Body as a whole: balance, coordination and agility

Nociception: Danger sensors: 'Noci' means pain, and the brain references nociceptors first answering the question, "Am I in Danger?"

Exteroception: Environment, in which our five senses contribute

Interoception: internal systems: digestion, breath regulation, hunber, digestion, acute ailments

So there's me, and the things going on in my body, as they relate to my environment and my body has to occupy a space in that environment. And at all times our brain is asking, "Am I safe?"
