CSD 1237: Basal Forebrain refers to a region in the brain located near the bottom (ventral) part of the forebrain. It plays a crucial role in several key functions, particularly in cognition, memory, and attention. The basal forebrain is involved in the production of acetylcholine, a neurotransmitter essential for learning, memory, and attention. Damage to this area is linked to cognitive impairments, such as those seen in Alzheimer’s disease. This region also interacts with other brain structures, including the hippocampus, and helps regulate the brain’s overall arousal and alertness.
