Though the brain may seem impossibly complex, it can be understood as a network, much like computer chips or the Internet. A new analysis in the journal PLoS ONE has described the workings of a worm's nervous system as patterns involving the connections among nerve cells with different functions.
A study of the salamander brain has led researchers to discover a hitherto unknown function of the neurotransmitter dopamine showing that dopamine controls the formation of new neurons in the adult brain.Their findings may contribute to new treatments for neurodegenerative diseases.
The moment we open our eyes, we perceive the world with apparent ease. But how neurons in the retina encode what we “see” has been a tricky a tricky one. A key obstacle to understanding how our brain functions is that its components respond in highly nonlinear ways to complex stimuli.
