Papez Circuit

The Papez circuit is a neural pathway in the brain first described by American neuroanatomist James Papez in 1937. Papez believed that the circuit was involved with emotions. Since the circuit's discovery, many experiments have been conducted to explore the system and how its structures work together. Recent studies show that it has a more significant role in memory functions than in emotions. The Papez circuit was later modified by American neuroscientist and physician Paul D. MacLean and now, the circuit is known as the limbic system. Damage to parts of the Papez circuit have shed light on not only its function, but on possible diagnosis of many disorders relating to memory.
