Nerve cells let others 'listen in'

How many 'listeners' a nerve cell has in the brain is strictly regulated. This is shown by an international study led by the University College London and the universities of Bonn, Bordeaux and Milton Keynes (England). In ...

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 ...

Neuroscience

How synaptic vesicles accumulate glutamate

In the brain, neurons communicate via neurotransmitters, which trigger electrical signals in downstream neurons by binding and activating specific receptors. Neurotransmitters are released through the fusion of synaptic vesicles, ...

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 ...

Novel sensors enable precise measurement of dopamine

Dopamine is an important signaling molecule for nerve cells. Its concentration could not be precisely determined with both high spatial or temporal resolution until now. A new method has now made this possible: A research ...

Synaptic transmission: Not a one-way street

Information flows in a well-defined direction in the brain: Chemical and electrical signals are passed from one neuron to the other across the synapse, from the pre-synaptic to the post-synaptic neuron. Now, Peter Jonas and ...

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 ...
