Robogator with Rat

Caption: Pictured is a LEGO Mindstorms robot programmed to simulate predatory attack on a rat seeking food in a semi-naturalistic environment. The findings demonstrate that without the functioning amygdala and consequently devoid of fear, the animalís foraging behavior becomes perilously maladaptive, whereas an overactive amygdala hinders foraging decision even under safe circumstances.
