Autism spectrum disorders

Scientists reverse disorder of neuronal circuits in autism

People with autism suffer from a pervasive developmental disorder of the brain that becomes evident in early childhood. Peter Scheiffele and Kaspar Vogt, Professors at the Biozentrum of the University of Basel, have identified ...

Neuroscience

Researchers define function of an enigmatic synaptic protein

In the brains, neurons communicate by sending chemical signals across synapses. The molecular machinery required to send a signal involves not only the neurotransmitter signal itself, but a large variety of other proteins ...

Use it or lose it

An Ludwig Maximilian University of Munich study reveals that sound-evoked activity of neurons in the auditory system of the mouse increases the thickness of their myelin sheaths - and enhances the speed of signal transmission ...

Neuroscience

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 ...

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 ...
