One The basal forebrain is a complex of subcortical nuclei with projections to brain areas critical to cognition; consequently, it is poised to play an important role in information processing, and damage to the basal forebrain is associated with cognitive deficits, ranging from amnesia to attentional impairments. Concomitant damage to the corpus striatum and basal forebrain is known to cause more serious memory loss. Acetylcholine affects the ability of brain cells to transmit information to one another, and also encourages neuronal plasticity, or learning.

Bilateral Pathways from the Basal Forebrain to Sensory Cortices May Contribute to Synchronous Sensory Processing. Although there is a large body of animal data indicating that basal forebrain structures play a part in memory, the human evidence is limited to a few case studies. The basal ganglia are situated at the base of the forebrain and top of the midbrain. Thus, damage to the basal forebrain can reduce the amount of acetylcholine in the brain and impair learning.
