An internal sensation and perception also known as interoception [44] is "any sense that is normally stimulated from within the body". [45] These involve numerous sensory receptors in internal organs. Interoception is thought to be atypical in clinical conditions such as alexithymia. [46] Specific receptors include:
Taste–odor integration occurs at earlier stages of processing. By life experience, factors such as the physiological significance of a given stimulus is perceived. Learning and affective processing are the primary functions of limbic and paralimbic brain. Taste perception is a combination of oral somatosensation and retronasal olfaction. [1]
Sense organs are transducers that convert data from the outer physical world to the realm of the mind where people interpret the information, creating their perception of the world around them. [ 1 ] The receptive field is the area of the body or environment to which a receptor organ and receptor cells respond.
Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials. [1] This process is called sensory transduction. The cell bodies of the sensory neurons are located in the dorsal root ganglia of the spinal cord ...
The communication within and among these specialized areas of the brain is known as functional integration. [3] [4] [5] Newer research has shown that these different regions of the brain may not be solely responsible for only one sensory modality, but could use multiple inputs to perceive what the body senses about its environment.
Perceptual adaptation is a phenomenon that occurs for all of the senses, including smell and touch. An individual can adapt to a certain smell with time. Smokers, or individuals living with smokers, tend to stop noticing the smell of cigarettes after some time, whereas people not exposed to smoke on a regular basis will notice the smell instantly.
Synesthesia is when input from one sense triggers the brain to associate it with another sensory experience. Dr. Hersh: Synesthesia occurs when more than one sense is experienced simultaneously ...
The process of perception begins with an object in the real world, known as the distal stimulus or distal object. [3] By means of light, sound, or another physical process, the object stimulates the body's sensory organs. These sensory organs transform the input energy into neural activity—a process called transduction.
