Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.
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.
Optogenetics has revealed that synaptic vesicles can be recycled extremely rapidly in nematodes, indicating that existing models for how synapses 'reload' may need to be revised.

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.

A small molecule, cotransin, blocks transmembrane domains form integrating into cell membranes by allosterically ‘locking’ the lateral gate of the Sec61 translocation channel.
