Brain cell death in zebrafish larvae exposed to ammonia. 3 dpf zebrafish larvae exposed to either 5 mM NH4Ac (A and C) or 5 mM NaAc (B and D). Fish were monitored for heartbeats and photographed immediately after cessation of heartbeat in fish immersed in NH4Ac. Arrows indicate necrotic brain tissue.
