• Brain-based localization and body-schema of cutaneous sensation emerges as a unifying theme, revealing bilateral representations, selective extinction/allesthesia, and central integration across cortical and thalamic systems [4], [15], [7], [1], [20], [18].

• Autonomic-sensory interfaces show cortex and autonomic nervous system jointly regulate skin reflexes and sweating, mapped via galvanic skin response, skin resistance, and pharmacologic modulation, illustrating integrated somatic-autonomic control [6], [5], [12], [14].

• Peripheral nerve fiber studies trace conduction pathways for pain and touch, relate these to nerve injury and compression, and discuss denervation supersensitivity, forming a framework for how peripheral conduits shape sensation before central processing [8], [11], [10], [19].

• Brain stimulation studies provide causal mapping of sensory and motor responses in forebrain, midbrain and tegmental regions, supporting functional localization and integration beyond perception to physiological regulation [3], [9].

• Thermoreception and thermoregulation synthesize peripheral thermal sensation and central hypothalamic control into homeostatic pathways, linking conscious temperature experience with autonomic regulation [4], [16].
