Mushroom bodies

The mushroom body is a prominent, paired, anatomical structure in the central brain of insects and other arthropods and some annelids.

It is divided into Calyx ( calyx ), peduncle ( stalk) and (usually more ) praise. The mushroom body is the seat of higher integrative services such as learning and memory and consists of numerous ( 50,000 in the migratory locust, about 2,000 in Drosophila ) intrinsic neurons, the Kenyon cells so called, whose cell bodies are located at the rear top and their dendrites in the calyx. Send The parallel axons of Kenyon cells form the peduncle and extending from the top back to front down across the insect brain, where they branch and form their appointment Alien beta-, gamma- and alpha- praise. In Drosophila, the paired mushroom bodies are formed on one side by four neuroblasts, which each produce an identical set of Kenyon cells.
