Decoding Decision-Making: Insect Brains Are More Complex Than We Thought
The mushroom body—a key area in the brains of arthropods like insects—plays a crucial role in abstract behavioral decision-making.
Contrary to the long-standing belief that insects react purely on stimulus-response, the study shows they can actually make nuanced decisions based on experiences. The researchers recorded feeding behavior alongside neural signals.
The mushroom body in arthropod brains encodes for both memory formation and complex decision-making, contesting prior views that insects operate merely on a stimulus-response basis.
The research involved the American cockroach, chosen for its relatively large brain, making it easier to measure and interpret neural signals and behavior in real-time.
The output neurons of the mushroom body also take into account the current state of the animal, like whether it is hungry, enabling more precise prediction of behavior.

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
