![]() ![]() The authors suspect that the signaling ensures that connections established in the absence of cellular communication work properly in larger networks of neurons that collaborate to carry out specific functions. Of note, the consistent firing bursts reflect patterns of connectivity that have already been recognized in the adult fly’s brain. The scientists imaged the electrical activity of 15 types of neurons in the brain region involved in processing vision. All of the cells fired signals at each other for two days until the adult fly emerged. ![]() The findings suggest that the signals could help neurons find each other to form networks and wire the developing brain. The coordinated activity appears to be internally driven - not triggered by something outside of the brain. Using fruit flies, neuroscientists from the David Geffen School of Medicine at UCLA observed that neurons displayed periodic bursts of electrical activity early in brain development, when the larva is still developing. Neurons somehow know which of their neighbors to connect with and which to avoid in the crowded environment of the central nervous system. ![]()
