Decisions between two alternatives have been extensively studied and modeled. A study now reports that during choices among several options, the responses of neurons in the lateral intraparietal area are still well described by the integration-to-bound model, supporting the general applicability of this computational framework.
A new study shows that microRNA-9 regulates multiple processes near the organizing centers during early brain development in zebrafish, revealing previously unknown modes of action for microRNAs in the nervous system.
Neurotrophins are recognized for their role in sustaining neuron survival and promoting axon growth. New studies reveal that they can also facilitate both neuron death and axon pruning by mechanisms that have much in common.
A new study in Nature finds that the retinal pathway transducing lighting information to the circadian clock is anatomically wholly independent of the visual pathways.
