Research Interests

Dr. Meinertzhagen’s work has pioneered studies on simple invertebrate nervous systems, especially the immaculately precise fly's visual system and the numerically diminutive nervous system of the ascidian tadpole larva, and has examined structurally identified circuits of neurons, their functional anatomy, their origins in both ontogeny and evolution, and their plasticity in adult animals.
