Summary: When adult brain cells are injured, they revert to an embryonic state, say researchers. In their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.

How old is the human brain?

40,000 years oldThe modern human brain may only be 40,000 years old, scientists say. Homo sapiens have been around for about 200,000 years. But our modern-shaped human brains may have only come into existence about 40,000 years ago, researchers say.

Is there a brain in your heart?

Recent findings: Dr. Armour, in 1991, discovered that the heart has its “little brain” or “intrinsic cardiac nervous system.” This “heart brain” is composed of approximately 40,000 neurons that are alike neurons in the brain, meaning that the heart has its own nervous system.
