Major content areas include: Foundational theories of perception (Gestalt principles, Gibsonian and computational approaches, information processing) Brain anatomy and sensory specialization (e.g., occipital, temporal, parietal lobes, somatosensory cortex) Neuroscientific methods (EEG, fMRI, microelectrodes, lesion studies) Somatosensation and touch: mechanoreceptors (SA/FA types), tactile agnosia, proprioception, thermoreceptors, and nociceptors Pain systems: Gate Control Theory, types of pain (neuropathic, inflammatory, emotional), analgesia, dorsal horn, A-delta and C-fibers Smell and olfaction: receptor pathways, anosmia, odor adaptation, olfactory bulb, piriform cortex, tip-of-the-nose phenomenon Taste and gustation: papillae, taste buds, receptor and presynaptic cells, umami, oleogustus, gustatory cortex, retronasal olfaction Also explored are unique phenomena like phantom limb syndrome, Pinocchio illusion, tactile illusions, and cross-modal sensory interactions. Each concept is paired with clear answers to reinforce learning and ensure test-readiness. Perfect for: Psychology students at UIUC enrolled in PSYC 230 Pre-med, neuroscience, biology, or health science students needing in-depth understanding of sensory and perceptual systems Anyone preparing for cognitive psychology exams with a strong physiological and applied focus Keywords: gestalt psychology, sensation, perception, psychophysics, signal detection theory, transduction, somatosensation, mechanoreceptors, nociceptors, thermoreceptors, tactile agnosia, pain processing, gate control theory, analgesia, olfaction, anosmia, olfactory bulb, gustation, taste receptors, papillae, retronasal olfaction, phantom limb, PSYC 230, UIUC
