PSY290H1 Lecture Notes - Second Messenger System, White Matter, Posterior Column
Document Summary
How capture environmental stimuli and convert to ap signal travel to brain understand meaning of environmental stimuli. 4 senses, bc vision is covered in psy280, chapter 6 not covered. Shared mechanisms of all the different sensations general principla governeing all 5 sensroy pathways. Env stimuu phsy or chemic tranfromed into neual signal nerve system understand and when received by cns, lots of neural processing to provide meaning to those env stimuli to generate proper behavior output. Env stimuli captured by specialized cells and once stimuli captured by receptor cells conv to ap propagate along axon till arrive at cns. Look at sensory organ find specialized cell or structure that captures env stimuli all different shapes. Ear hair cells that capture sound signal all dif structure and specialized for all difernt sensory system specific stimuli. Big difference between somat and other receptors. Somat what capture env stimuli is not cell body but nerve ending, cell body is located far from skin.
