Document Summary
Does not want to respond and needs a lot of stimulus to say they felt it: what is sensory adaption, a decrease in sensitivity to a constant level of stimulation, ex. Sour, sweet), smells, touch sensations, auditory information, and what parts of the brain each type of info is sent to: taste- taste buds on tongue/mouth/throat are stimulated and signals are sent to the brain. The prefrontal cortex determines if a smell is pleasant or not. Different receptors are sensitive to different smells: touch- tactile stimulation comes from contact with our skin. Sensory neurons to the outer layer detect temperature and pressure. Signals enter the cns and to the brain. Hot and cold sensation at once can produce a false feeling of wetness, for example. Stroking multiple pressure points is pleasant or unpleasant (tickling) depending on the person"s mood: hearing- a sound wave moves through the ear canal and vibrates the eardrum.
