Our vestibular sense/system provides us w/ information about our movement through space which stops working if we are on a ship that is rolling & pitching on rough waters. Cutaneous senses/somatosenses is basically the touch sense incl pressure, vibration, pain, temperature & position. Each of the senses has a set of specialized sensory receptor cells which convert a specific form of environmental stimuli into neural stimuli. Sensory transduction is the form of communication used in our brains & the nervous system which is the process of converting the specific environmental stimuli to neural impulses. The absolute threshold is the minimal stimulus necessary for detection by an individual. Absolute thresholds vary from person to person but in most cases are small. The difference threshold or just noticeable diff (jnd) is the minimal diff b/w 2 stimuli necessary for detection of a diff b/w the 2. Jnd depends on how loud it was in the 1st place.
