The word 'anahata' means 'unstruck sound' and it is known by that name, because it is believed to be the center of nada, the Hindu center of inner voice. Anahata chakra, or heart chakra, is the fourth chakra of the body and like other chakras, it is connected to the brain. The part of the brain that fosters creative abilities within us like that of music, dancing, writing etc., is linked to this chakra.
