What does subluxation reduce in the body?

Subluxation primarily affects the brain's cortical summation due to its impact on the nervous system. When there is a subluxation, which refers to a partial dislocation or misalignment of the vertebrae, it can interfere with the normal transmission of nerve signals. This obstruction can lead to disruptions in how sensory information is processed and integrated within the brain.

The concept of cortical summation involves the brain’s ability to accumulate incoming sensory signals to effectively respond to stimuli. If subluxations exist, they can hinder this accumulation process, leading to altered sensory perceptions and responses. This reduction in cortical summation may result in various symptoms, including decreased motor function or altered reflexes, as the nervous system's ability to process information correctly is compromised.

While spinal flexibility, sympathetic nerve activity, and motor neuron responsiveness are also influenced by spinal health, the most direct and fundamental effect of subluxation is on the pathway through which sensory information integrates in the brain, making brain/cortical summation the key factor in this context.
