Document Summary
In order to have sensation 3 things are needed: 1. Our sensational organs must be able to detect a physical energy 2. Then the physical energy must be translated into a message the brain will understand (neural message) 3. Once it has been converted into a neural message it must be sent to the brain to be processed. Sensory receptors: these receptors are found on highly specialized cells, they don"t use neural messages, but they detect the physical energy and they are the ones to translate and transmit. Perception: the information that is collected by the brain which will than select parts of the info and organize them then process them and final precept them in a meaningful way. Bottom-up processing: it"s when you start with the most basic information and build up to more developed and complicated info, sensory info is a bottom-up form of info.
