Document Summary

It is the basic neural response to stimuli. The se(cid:374)sory syste(cid:373)"s disti(cid:374)ct receptors and neural pathways. Various forms of energy: sensory receptors. Specialized structures that respond to physical stimuli by producing electrical changes that can initiate neural impulses in sensory neurons. According to the first law of thermodynamics, these forms of energy get converted into neural signals and action potentials. Specialized neurons that carry information from sensory receptors into the central nervous system action potentials (like between a rod or a cone, and the glomeruli) Sensory areas of the cerebral cortex: primary sensory areas of the cerebral cortex: shown here are the locations of the primary cortical areas for vision, hearing, somatosensation (which includes touch, temperature sensitivity, and pain), taste, and smell. The primary taste area lies in a portion of the cerebral cortex called the insula, which is buried in the fold between the parietal and temporal lobes.
