How do we programme our neurons
Sensory cells (also called sensory receptor cells ) are specialized cells that detect changes in the body or environment and convert them into electrical signals for the nervous system. How they work Stimulus → Sensory receptor cell → Electrical signal → Sensory neuron → Brain & spinal cord → Perception or response Examples of sensory cells Photoreceptors (eyes) – detect light. Hair cells (inner ear) – detect sound and balance. Olfactory receptor cells (nose) – detect smells. Taste receptor cells (tongue) – detect sweet, sour, salty, bitter, and umami. Mechanoreceptors (skin) – detect touch, pressure, and vibration. Thermoreceptors (skin) – detect hot and cold. Nociceptors (skin and tissues) – detect pain. Chemicals inside sensory cells Water (H₂O) Cell membrane (phospholipids and cholesterol) Proteins (ion channels, receptors, enzymes) DNA RNA ATP (C₁₀H₁₆N₅O₁₃P₃) Ions: Na⁺, K⁺, Ca²⁺, Cl⁻ Neurotransmitters (depending on the sensory system), such as glutam...
