Glowing heart with branching neural pathways in dark atmosphere

Digital rendering depicts anatomically stylized heart with intense crimson luminescence radiating through translucent tissue structure. Branching vascular and neural elements extend outward with fibrous texture. Warm red-orange core transitions to dark charcoal periphery. Particle effects scatter throughout composition. Atmospheric depth created through gradient tonal modulation from green-tinted shadows to orange highlights. Technical execution employs volumetric lighting and subsurface illumination simulation. Compositional focal point centered with radial energy distribution.
