    Sensation can be defined as the physical trait that captures sensory information and transforms it for use by the brain. In other words, sensation is the transduction of energy (e.g. light or sound) into neural impulses. Depending on types of human sensory organs, Bailey (1996) accounts for five traditional senses viz. vision, hearing, smell, taste and touch. For each senses there are specific sensors/ receptors which helps in transformation/transduction of environmental stimuli (odour, sound etc.) into neural impulses. Thus, sensory receptors are act as biological transducers. Locations of biological transducers are given in Table 1.
