What effect does reduced brain summation have on the nervous system?

Reduced brain summation refers to the decreased ability of the brain to integrate and process sensory information, which can lead to a state of dis-inhibition regarding the sympathetic nervous system. When summation is reduced, the usual inhibitory control that the central nervous system exerts on the sympathetic nervous system is less effective. This can result in an increased sympathetic response, which often presents as heightened alertness or anxiety, elevated heart rate, and increased blood pressure.

This phenomenon is important in the context of chiropractic theory, as it underscores how neurological pathways and the brain’s processing abilities are interconnected with the autonomic nervous system. By reducing the inhibitory mechanisms, the body may not effectively manage stress responses, leading to an overactive sympathetic system. This concept highlights the delicate balance maintained by the nervous system in regulating bodily functions and responses to stimuli.
