Send coherent and physiological information to the Central Nervous System to reprogram the neuromuscular signal and modulate the efferent response, normalize the muscle-fascial tone-trophism, the contractile capacity of the fibers and activate the related metabolic processes.
NEUROTRANSMISSION AND NEURONAL PLASTICITY
As we all know, through stimuli that come from outside and inside our body, a continuous flow of information is organized with our brain.
This information starts from the periphery and travels through receptors (mechanoreceptors, chemoreceptors, thermoreceptors), nerve fibers (peripheral nervous system), molecules and hormones.
Once arrived at the Central Nervous System (CNS), this information flow is processed and, instantly, response signals are transmitted.
The CNS therefore governs and regulates the osteo-tendon-muscular system through an input (afferent) and output (efference) communication network.
Today we know that the brain constantly uses this information and is able to change itself in relation to the stimuli it receives. This phenomenon is defined as Neuronal Plasticity. To obtain this plasticity, the stimulus must be ADEQUATE in terms of intensity, frequencies and amplitude. Each receptor is activated in relation to its specific stimulus which it transmits to the nerve ending, activating it without causing damage.
Pacinian corpuscles
Afferent and efferent signals
The Pacinian corpuscles are undoubtedly the mechanoreceptors most involved in vibrational perception. (Maximum activation sensitivity at 300 Hz, a frequency at which a pressure of 1 μm is sufficient to be activated).
Afferent signals come from external stimuli and send information to the central nervous system. Afferent neurons carry stimuli to the brain, via the spinal cord and thalamus. In this way, the signal is integrated and processed. The brain then coordinates a response through efferent signals that return to the rest of the body.
Efferent signals carry the message from the central nervous system to the muscles that activate the stimulus.
- Type I exteroreceptors, are nerve endings covered by numerous layers of collagen lamellae that recognize external stimuli;
- Unimodal, they are activated exclusively by pressure;
- Phasic, they adapt quickly – They follow the all or nothing principle . Either they are activated or not.
