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.

What is Telegram?
Telegram is a cloud-based instant messaging service that has been making rounds as a popular option for those who wish to keep their messages secure. Telegram boasts a collection of different features, but it’s best known for its ability to secure messages and media by encrypting them during transit; this prevents third-parties from snooping on messages easily. Let’s take a look at what Telegram can do and why you might want to use it.
