The adult nervous system of a C. elegans worm contains 302 neurons, which can be divided into 118 types. Seventy homeobox genes are involved in characterizing the neuron types.
Neurons created as a result of adult neurogenesis mature for longer and grow larger than those created during infancy. Findings suggest adult-born neurons may have a more powerful function than those created during infancy and may play a critical role in neuroplasticity.
Researchers have identified a group of glucose-sensing neurons in the ventrolateral area of the ventromedial hypothalamic nucleus and discovered how they work together to prevent hypoglycemia in mice.
A new study puts into question conventional belief that the eyes communicate with the brain exclusively via one signaling pathway. Researchers have identified a subset of retinal neurons that sends inhibitory signals to the brain. This subset of neurons is also involved in the synchronization of circadian rhythms to light/dark cycles and pupil constriction to bright light intensity.
GABA can selectively regulate the excitability of neurons.
A single neuron, through its axon, is capable of simultaneously producing different effects in separate areas of the cerebral cortex.
Study reports repeats in genes associated with Fragile X syndrome normally regulate how and when proteins are made in neurons.

The lessons learned from developing artificial intelligence networks can help guide researchers down the path of understanding the brain as a computational system rather than a collection of cells. AI technology can help take exploring the human brain, behavior and neurodegenerative diseases to an entirely new level.
The way neurons are structured, and the patterns they make can be used to explain how they behave and function. The findings have implications for creating intelligent robots.

FlyEM, a team of scientists from Google and the Janelia Research Campus at Howard Hughes Medical Institute, has released the most complete map of the fly brain ever created. The map pinpoints millions of connections between 25,000 neurons. The researchers have made the data free online, along with all of the tools necessary to use it.
