Zebrafish Larvae

Caption

Small prey-like items elicit a quick response from zebrafish larvae, as excitatory brain cells fire. However, large visual stimulus covering the zebrafish's field of vision fires off inhibitory cells, and the zebrafish responds less to it. This mechanism allows the zebrafish to have a good hunting response to the appropriate visual cues, and not bite off more than it can chew.
