3-D tour of intact mouse brain
CLARITY makes possible this 3D tour of an entire, intact mouse brain. It was imaged using a fluorescence technique that previously could only be performed with thinly-sliced brain tissue, making it difficult to relate micro-level findings to macro-level information about wiring and circuitry.
