Sensory Integration - Organization of Somatosensory System: Receptor level: sensory receptors Circuit level: ascending pathways Perceptual level: neuronal circuits in cerebral cortex - Processing at Receptor Level: Transduction by sensory receptors : a stimulus alters permeability of membrane receptors, leading to a local graded potential or receptor potential (like EPSP)… if the receptor is a separate cell (nonneuron), depolarization is called a generator potential o If the receptor potential is at or above the threshold, an action potential will be Adaptation by sensory receptors : some receptors (pressure, touch, smell) become insensitive to the same stimuli over time (don’t notice feel of clothing after some react to stimuli) - Processing at Circuit Level: ascending pathways conduct sensory impulses upward o first-order neurons: conduct impulses from sensory receptors to brain stem or
