Examples
- The lenticular nucleus is a critical component of the basal ganglia, playing a key role in regulating movement and cognition.
- The putamen and pallidum are the two main divisions of the lenticular nucleus, which is situated deep within the cerebral hemisphere.
- Damage to the lenticular nucleus can result in movement disorders, such as dystonia and chorea, due to its involvement in motor control pathways.
- The lenticular nucleus receives input from the cerebral cortex and sends output to the thalamus, influencing motor function and coordination.
- In neuroanatomical studies, the lenticular nucleus is often examined in conjunction with other basal ganglia structures to understand their complex interactions.
