Document Summary
Organization sensory systems: what are the three parts of all sensory systems, sensory receptors. We can only see visible light: what is transduction when you are talking about receptors, receptors transduce energy. A specific part of the world to which it responds. Your receptive field allows you to locate: receptors allow distinction between self and others. Where the stimuli that the receptors are reacting to, coming from (outside vs. inside) Exteroceptive receptors what is going on outside (i. e. visual) Interoceptive what"s going on inside: how does receptor density determine the sensitivity, receptor density determines sensibility. Can allow for a hierarchy of motor responses. Allow sensory system to produce relevant actions: i. e/ pain receptors. Message modification takes place at relays stimulation in those pain receptors. Impulses from cortex can amplify or block pain signals at the level of the brain stem.
