Insula
The insula is a recessed part of the cortex (cerebral cortex) that is covered by the frontal, temporal, and parietal lobes. This overlay is called the opercula (lid). The insula influences the motor and sensory functions of the intestines and is considered to be the link between cognitive and emotional elements in pain processing. It is also involved in processes such as taste and physical self-awareness.

Confabulation
Confabulation refers to a memory or explanation that the person concerned is completely convinced is true, but which is objectively false. There is no conscious intent to deceive behind this. The cause is usually medical, such as damage to the orbitofrontal or other frontal brain areas, amnestic syndrome (e.g., Korsakoff's syndrome), traumatic brain injury, or dementia.

Operculum
Cortical areas of the frontal, temporal, and parietal lobes at the lateral sulcus. The operculum covers the insular cortex.

Parietal lobe
The parietal lobe is one of the four large lobes of the cerebral cortex. It is located behind the frontal lobe and above the occipital lobe. Somatosensory processes take place in its anterior region, while sensory information is integrated in its posterior region, enabling the handling of objects and spatial orientation. In addition, the parietal lobe is involved in attention, the recognition of body parts and objects, as well as linguistic and mathematical abilities.

Premotor cortex
Part of the motor cortex in the frontal lobe. It is connected to the primary motor cortex and numerous other brain regions and is involved in the planning, preparation, and coordination of complex, voluntary movements. Examples of its functions include reaching for an object or the sequence of movements involved in targeted actions.

Primary motor cortex
An area of the frontal lobe in the anterior wall of the central sulcus. It is considered to be the higher-level control unit responsible for voluntary and fine motor skills. This is where the cell bodies of the central motor neurons are located, whose axons primarily extend to the spinal cord (via the corticospinal tract). Only in the primary motor cortex do Betz giant cells occur, which are particularly large motor neurons whose axons extend directly to the motor neurons in the anterior horn of the spinal cord without prior synaptic switching.

Supplementary motor area
Area of the association motor cortex in the frontal lobe that is involved in movement planning and the organization of movement sequences.

Ventromedial prefrontal cortex
Anatomically, the ventromedial prefrontal cortex belongs to the frontal lobe of the cerebral cortex. In some patients with decision-making problems, neuroscientists find lesions in this region of the brain. The ventromedial prefrontal cortex also becomes active when we try to suppress negative emotions such as feelings of guilt. It receives signals from many other areas of the brain and innervates the amygdala, hypothalamus, and several areas of the cortex.
