What is P-DTR?

Introduction

​

In order to perceive the external and internal states of its environment, the central nervous system (CNS) uses various types of sensory receptors which convert properties of the environment into electrical signals or impulses. The magnitude of these signals is proportional to the strength of the stimulus and does not code the quality of the irritant itself.

Each type of stimulus is detected and received by specific nerve endings, and the signal is carried in the CNS by specific pathways. Each sensory receptor adapted to detecting mechanical, chemical, nociceptive (painful), or thermal stimuli. Stimulation of a sensory receptor sends a nerve impulse (sensory transduction, i.e. transformation of a signal) and this incoming sensory information is then conveyed via the fibers of cranial or spinal nerves to their respective relay nuclei in the central nervous system. The sensory information is processed further on via pathways to the cerebral cortex or cerebellum. It may also relay to other parts of the CNS where it would elicit a reflex response or get integrated into a pattern-generating activity.

​

Nervous system activity may be seen as two sides of a coin. On one side, as incessantly incoming information, transformed by receptors into specific signals characterizing the external and internal environment, and on the other, as a constant signals from the brain which, in composite, control the effectors: muscles, glands and all systems responsible for managing the internal environment, as well as the process of adjustment an adaptation of the body under the ever-changing conditions of the external environment. The nervous system analyzes the independent pieces of sensory information into basic constituent signs in order to later synthesize complex identifiers of signals and situations and, ultimately, to generate a behavioral reaction (body positioning, centering, dynamic movement, organ function, etc.).

​

If the incoming information is correct and reaches the targeted area of the CNS, the body is characterized by optimal statics, correct dynamics and adequate behavioral responses.

​

A person with such a CNS is considered healthy on physiological, emotional and mental levels. Each functional system of their body works perfectly. The brain receives the optimal information from the environment and the body – i.e. from the exteroreceptors and proprioceptors – and generates an appropriate output.

​

What happens when a receptor distorts the incoming information? Since the body is a system of functional correlations, the response from the nervous system in this case will be incorrect (distorted), which will lead to a dysfunction.

Disease (dysfunction) is an inaccurate interpretation based on aberrant information, creating and impaired capability of the CNS to adapt to external and internal factors (physiological, ecological, emotional, etc.). P-DTR clearly shows and explains the source of the aberration in the processed information and provides the structured method for resolving the problem.
