PSY290H5 Chapter Notes - Chapter 5: Bulbous Corpuscle, Lamellar Corpuscle, Sensory Neuron
Document Summary
Part 1: sensory processing and the somatosensory system. All animals have sensory organs containing receptor cells that sense some forms of energy called stimuli but not others. So in a way, receptor cells act like our filters (ignoring the unimportant stimuli surrounding us and allowing us to notice the important ones). They then convert the key information into electrical signals (the language of the nervous system) Labelled lines = neurons that are labeled for distinctive sensory experiences. Receptor cells convert sensory signals into electrical activity: An electrical change in the receptor is called the generator potential. Sensory transduction = converting the signals from our environment to action potentials (what our brain can understand) A skin receptor that provides a clear example of the process of sensory transduction is the. Pacinian corpuscle (a tiny onion like structure embedded in the innermost layer of the skint at selectively responds to vibration and pressure).
