What You Should Know About the Peripheral Nervous System
The autonomic system controls aspects of the body that are usually not under voluntary control. The autonomic system is divided into two branches:

Strength training is more physiologically intricate than initially realised. When we start to lift weights, our muscles are not the first to strengthen and change. However, our nervous syst...
Scientists have known for some time that early increases in strength involve changes in the connections between the brain and muscles.
Particular bundles of neurons and nerve fibers carry commands from the brain's motor cortex to the spinal cord to the muscles. When the neural input to your muscles increases, the commands become more forceful, and the muscles should respond similarly. When strength training, the initial gains are about strengthening the reticulospinal tract. Only later do the muscles start to grow.
Consciousness is everything you experience - taste, pain, love, feeling. Where these experiences come from is a mystery.
Many modern analytic philosophers of mind either d...
What is it about brain matter that gives rise to consciousness? In particular, the neuronal correlates of consciousness (NCC) - the minimal neuronal mechanisms jointly sufficient for any conscious experience.
Consider this question: What must happen in your brain for you to experience a toothache?
The whole brain can be considered an NCC because it generates experience continually.
Congenital Insensitivity To Pain (CIP) is a rare genetic condition in which a person does not feel any pain, with no warning signs of ‘hurt’ being registered in the brain even after the body gets injured or damaged.
No one with this condition survived till adulthood due to them not able to act on the(unfelt) pain, which could have saved their lives.
The very concept of pain, where it locates and provides the severity of the problem, is an extremely important part of the human body mechanism, as it operates on various dimensions.
As soon as we touch a hot pan (thermal), our hand is located by the brain, along with the intensity, which is extremely unpleasant and diverts your thoughts towards it, demanding full attention (cognition), making us feel unhappy (emotional).
