Brain more robust than previously thought

The brain is well capable of coping with the erratic way individual brain cells transmit information. This robustness is quite useful because variation in signal transmission doesn't merely concern noise, but also contains ...

Myelin cells swing along blood vessels to traverse the brain

The cells that create myelin, a fatty material that insulates nerve fibers in the brain's white matter, migrate into the developing brain by climbing and swinging on blood vessels, according to new research led by UC San ...

Neurobiology—tuning of timing in auditory axons

Ludwig Maximilian University of Munich team has shown that the axons of auditory neurons in the brainstem which respond to low and high-frequency sounds differ in their morphology, and that these variations correlate with ...

Neuroscience

Dopamine-producing neurons fulfil important function in the brain

Nerve cells that produce dopamine for the purpose of transmitting signals to other cells affect numerous crucial brain functions. This becomes evident in diseases such as Parkinson's and schizophrenia, where dopamine transmission ...

Why some neurons 'outsource' their cell body

Nerve cells come in very different shapes. Researchers at the Bernstein Center Berlin now reveal why, in insects, the cell body is usually located at the end of a separate extension. Using mathematical models, they show that ...

Study reveals novel role for the Pin1 molecule

Synapses are "dynamic" things: they can regulate their action in neural processes related to learning, for example, but also as a consequence of diseases. A research team – led by SISSA – has demonstrated the role of ...

Neuroscience

New regulator discovered for information transfer in the brain

The protein mSYD1 has a key function in transmitting information between neurons. This was recently discovered by the research group of Prof Peter Scheiffele at the Biozentrum, University of Basel. The findings of the investigations ...

Newly understood circuits add finesse to nerve signals

(Medical Xpress)—An unusual kind of circuit fine-tunes the brain's control over movement and incoming sensory information, and without relying on conventional nerve pathways, according to a study published this week in ...
