The Parietal Lobe
Sensory impressions are integrated in the parietal lobe. This is also where the body and mind meet.

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.

Frontal lobe
The frontal cortex is the largest of the four lobes of the cerebral cortex and its functions are correspondingly comprehensive. The front area, known as the prefrontal cortex, is responsible for complex action planning (known as executive functions), which also shapes our personality. Its development (myelination) takes up to 30 years and even then is not yet complete. Other important components of the frontal cortex are Broca's area, which controls our ability to express ourselves linguistically, and the primary motor cortex, which sends movement impulses throughout the body.

The Corpus Callosum
The corpus callosum allows information to flow between the two hemispheres of the cerebrum. This is urgently needed.

Association cortex
Parts of the cerebrum that are not assigned to the primary and secondary areas for sensory processing and motor function. They are mainly located in the neocortex, integrate information from multiple sources, are the center of thalamocortical and cortico-cortical networks, and cannot be clearly distinguished functionally.

Forced Right-Handedness
When left-handed people were retrained to use their right hand, their brains were also retrained.

Betz giant cells
Betz giant cells are particularly large pyramidal cells in the primary motor cortex (area 4). They have very large cell bodies with a diameter of 100 µm and heavily myelinated axons that project directly into the spinal cord. This makes them part of the corticospinal neurons of the pyramidal tract. Although they make up only a small portion of the fibers of the pyramidal tract, they are functionally important for the control of voluntary movements, especially fine motor skills.

Nucleus tractus solitarius
A nucleus in the medulla oblongata that serves as an important integration center for visceral information. Among other things, it processes taste stimuli (via nerves VII, IX, and X) and transmits them via the thalamus (ventral posteromedial nucleus, VPM) to the primary gustatory cortex. The NTS is also involved in the motor functions of swallowing, coughing, and respiratory control by transmitting signals to motor nuclei such as the nucleus ambiguus. These reflexes serve to protect the respiratory tract and facilitate food intake.
