Human Sensory Systems

According to current neurobiology a human has 21 senses. This site will explore the research and define the sensory systems and what environmental elements those systems detect.


Each element in our universe may lend clues to the sensory systems that humans have employed to navigate through environments.Earth, air, fire, water, space, time, light, the void, life, sound, and physical sensation.

Our Access to the World Around Us

Sensory Detectors

There are detectors such as eyes and ears. There are also detectors that are like antennae buried deep in the skin safe from confounding stimuli.

The Brain Stem

The brain stem is the posterior part of the brain, adjoining and structurally continuous with the spinal cord. The brain stem includes the midbrain, the pons, and the medulla oblongata. The brain stem provides the main motor and sensory innervation to the face and neck via the cranial nerves.

Cerebral Cortex

Data from the detectors arrives here to present stimuli to the awareness of the organism for processing and integration with other lobes. The lobes of the cerebral cortex are programmed to recognize and make sense of stimuli.
