Asomatognosia
Asomatognosia literally means "not knowing" one's own body. The term refers to the loss of perception or feeling of belonging to one's own body parts. Asomatognosia is usually caused by damage to the right parietal lobe, which means that the left side of the body is usually affected.

Change blindness
Change blindness is a phenomenon of visual perception whereby changes in the environment are not noticed. It is a problem of attention that can also arise due to distraction or concentration on other things. In experiments, a scene that changes during masking or distraction is often shown. Test subjects are unable to perceive the change.

Diencephalon
The diencephalon (midbrain) includes the thalamus and hypothalamus, among other structures. Together with the cerebrum, it forms the forebrain. The diencephalon contains centers for sensory perception, emotion, and the control of vital functions such as hunger and thirst.

Taste bud
Taste buds are groups of taste cells in the oral mucosa and are therefore the site of taste perception.

Cerebrum
The cerebrum comprises the cerebral cortex (gray matter), the nerve fibers (white matter), and the basal ganglia. It is the largest part of the brain. The cortex can be divided into four cortical areas: the temporal lobe, frontal lobe, occipital lobe, and parietal lobe.Its functions include the coordination of perception, motivation, learning, and thinking.

Haptics
Haptic perception is based on the sensory cells of the skin and depth sensitivity. It is an active process that allows the shape, structure, weight, temperature, etc. of an object to be explored. Haptics is the "science of touch."

Hyperbinding
An explanatory model for the phenomenon of synesthesia. Those affected relate different aspects of perception such as shapes, colors, sounds, and smells so strongly to each other that they temporarily experience them as a single entity. To a certain extent, this "connection" occurs in all people. In synesthetes, however, it is particularly pronounced and also arises in areas of the perceptual spectrum that most people would not associate with each other.

Hypercomplex cell
A nerve cell in the primary visual cortex that responds most strongly to short, moving lines or corners in its receptive field. It exhibits end-stopping, meaning that the response strength decreases when the stimulus becomes longer than optimal. Hypercomplex cells are sensitive to the orientation and direction of movement of the stimulus and contribute to the perception of edges, corners, and curves.

Merkel cells
Merkel cells are slow-adapting mechanoreceptors in the skin. They respond to continuous pressure and are important for the perception of shape, edges, and fine details.
