Nicotinic Receptor and Long-Term Memory Study Paves Way for Targeted Dementia Therapy
Researchers report alpha 7 nicotinic acetylcholine receptors enhance communication between the hippocampus and frontal cortex, where as a4b7 nicotinic receptors decrease the communication. The findings may have implications for the way stimulation of acetylcholine can be used to treat dementia.... Read More...
