Brain regions for different sensory modalities cross-activate each other. Sensation - the act of using our sensory systems to detect environmental stimuli. Perception - recognizing and identifying sensory stimulus. Sensory receptor cells - specialized cells that convert a specific form of environmental stimuli into neural impulses. Sensory transduction - the process of converting a specific form of sensory data into a neural impulse that our brain can read. Absolute threshold is the smallest amount of a stimulus that one can detect. The difference between sensing and not sensing . Smell - a drop of perfume diffused throughout a six bedroom apartment. Taste - 5mm of sugar in 9 litres of water. Touch - an insect"s wing falling on your cheek from a height about a cm.
