• Diverting / Deviating — A term describing a factor, stimulus, nervous pathway, or structural element that induces a change of direction, reflection, or deviation of a physiological impulse or a biomechanical axis. In neurophysiology, it can refer to collateral neural pathways (shunts) that divert nerve impulses from their main path during central lesions, or an orthopedic device designed to correct the deviating axis of a limb affected by spasticity.
• Afferentation — A foundational physiological process consisting of the continuous transmission of nerve impulses and excitations from peripheral receptor neurons to the central nervous system neurons and cerebral cortex.
• Analgesia — The total absence, complete loss, or pathological or therapeutic diminution of sensitivity to pain, without the loss of consciousness or other sensory modalities (such as tactile or thermal sensitivity). In a structural clinical sense, it can occur as a symptom in severe neurological disorders (like syringomyelia or spinothalamic tract lesions) or can be deliberately induced through the administration of analgesics, local anesthesia techniques, or neurostimulation procedures for patient comfort.
• Autokinetic — Relating to the apparent and illusory movement of a fixed luminous point; used to describe an optical phenomenon where a static light stimulus observed in complete darkness appears to move autonomously.
• Autonomic — Relating to the vegetative nervous system, responsible for the automatic and involuntary regulation of vital bodily functions (such as heartbeat, digestion, respiration, or glandular secretions); a structural functional system operating independently of conscious voluntary control. In a clinical sense, it denotes the totality of sympathetic and parasympathetic fibers, ganglia, and reflexes that maintain internal homeostasis in response to environmental changes.
• Self-perception — A mental, cognitive, or sensory process through which an individual consciously perceives, decodes, and integrates their own internal states, emotions, impulses, or physiological signals; a structural reflexive act of becoming aware of the somatic and psychic self. In neurophysiology, it describes the nervous system's capacity to process native interoceptive and proprioceptive stimuli, forming the baseline for bodily identity and the mental representation of one's own ego.
