Percipience
See, hear, smell... we experience our sensations so everyday that they seem almost banal. But these windows into the world speak different languages - sound and touch are physical stimuli, smelling and tasting chemical, seeing lies between waves and particles - and all these languages must be translated into those of the nerves. And this is where the miracles from the engine room begin. Further up, on the more psychological levels, perceptions are deceived and there are interesting effects. Also interesting: Why can we perceive beauty? And then there's us - more precisely: our self. This is also a matter of perception.

Vision
About 80 percent of the information about the environment comes from our eyes. A good quarter of the brain is involved in processing this input.

Feeling
Uneven ground, the heat of the oven, a gentle caress on the arm – our body perceives a variety of stimuli, which it transmits to the brain.

Agnosia
The term agnosia comes from Latin and means "not knowing." It is a disorder of recognition caused by damage or dysfunction of the brain, without deficits in sensory perception. Agnosia is usually very specific, such as prosopagnosia, the inability to recognize a person by their face.

Anterior cingulate cortex
The anterior cingulate cortex (cingulate gyrus) plays a role not only in autonomic functions such as blood pressure and heart rate regulation, but also in rational processes such as decision-making. This area of the brain is also involved in emotional processes, such as impulse control. Anatomically, the anterior cingulate cortex (ACC) is characterized by a large number of spindle neurons (Von Economo neurons). These special nerve cells have a long, spindle-shaped structure and have so far only been found in mammals such as primates, elephants, and some whale and dolphin species. Spindle neurons contribute to higher social and emotional processes such as self-awareness, empathy, and quick emotional decisions. In pain perception, it is particularly associated with the affective component of pain – including social pain, such as that experienced through exclusion.

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.
