In the lateral part of the tuber cinereum is a nucleus of nerve cells, the basal optic nucleus of Meynert.

The basal nucleus of Meynert (NBM) is involved in production of acetylcholine. A decrease in this production is seen in Alzheimer's disease and Lewy body dementia, leading to a general decrease of mental capacity and learning. Most pharmacological treatments of dementia focus on compensating for a faltering NBM function through artificially increasing acetylcholine levels.
