Neglect
Neglect is a perceptual disorder in which parts of the body or stimuli are ignored due to a brain lesion. The disorder affects the sides opposite the brain lesion. It usually occurs after lesions in the right parietal lobe. Accordingly, visual, auditory, and somatosensory stimuli on the left side are ignored.

Alpha waves
Neuroscientists distinguish between different types of brain waves based on their frequency. Alpha waves oscillate in the mid-frequency range between approximately 8 and 12 hertz. They occur, for example, in a relaxed waking state, such as when test subjects are tired or have their eyes closed, i.e., when there is no mental activity. In the brain, they originate primarily in the parietal lobe. They are also called "Berger's waves" Hans Berger, who first described them.

Secondary somatosensory cortex
The posterior parietal lobe receives input from numerous other cortex areas - this is where visual, auditory and proprioceptive signals are integrated into a whole, enabling orientation and movement in space. The S2 cortex, located posterior and ventral to S1, is also involved in the conscious processing of pain.

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.
