The Notch signaling pathway has a central role in the development of the nervous system, and also in the establishment of networks of connections in the adult brain

Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.

Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

The Botryllus schlosseri genome yields insights into the evolution of hematopoiesis.

In individuals with a missing hand, the area of the brain that would otherwise control that hand is recruited by either the remaining hand or the residual limb, depending on the usage preference of the individual.

The signaling molecule Frizzled3 plays a part in the development of the nervous system by controlling the ability of motor neurons to form connections with distant target muscles.

Body shape and behavioural specializations found across the castes of ant species evolved together and reflect different abilities for ground behaviors.

Pair-rule genes in the wasp Nasonia function as in Drosophila in patterning anterior segments, and similar to ancestral insects in patterning posterior segments, illustrating a mixed-mode transition state between short and long germ embryogenesis.

A number of genes associated with the development of brain tumors are epigenetically repressed in specialized astrocytes to enable the production of neurons in the postnatal brain.
