The term 'solar plexus location' refers to the area of the body where the solar plexus is located. The solar plexus is a network of nerves located in the ABDOMEN, and is often referred to as the 'abdominal brain'. It is responsible for controlling the autonomic nervous system, which regulates involuntary bodily functions such as breathing, digestion, and heart rate. The solar plexus is located in the upper ABDOMEN, just below the ribcage.
