Create an image depicting a deep, interconnected relationship between the heart and the brain. The illustration should feature a human brain and heart, both glowing with vibrant, golden light. The brain and heart are connected by a stream of light or energy that flows between them, symbolizing their communication and unity. The background should be dark with subtle, sparkling stars, creating a sense of cosmic connection. Additionally, show two human figures, one on the left side representing the heart and one on the right side representing the brain, shaking hands, indicating harmony and agreement between emotion and intellect.
