Forget the traditional tubular shape—researchers are investigating a pearl-on-a-string formation for axons, unlocking new ...

The axon initial segment (AIS) is where nerve signals begin, and its adaptability is key to brain function. Scientists have found that the AIS changes in response to activity levels, helping neurons ...

Three new papers demonstrate a role for the axon guidance molecule semaphorin ... This allowed them to pick apart how olfactory receptor neuron (ORN) axons from the antennae and from the maxillary ...

Between the axon of a transmitting neuron and the dendrite of a receiving neuron is a gap called the synapse—the site at which signals are passed between the brain cells. The nervous system ...

These findings, published in Neuron, highlight the importance of lipid ... While this discovery sheds light on axon ...

Sphere of Influence. In iAssembloids, microglia (red) form projections (white arrows), while astrocytes (green) assume star shapes typically found in the brain. [Courtesy of Kampmann et al., 2025.] ...

Here, an axon from one neuron links to a dendrite of another. At these synapses, neurotransmitters carry signals across the ...

When I expressed the different protein constructs in neuron cells in culture, I demonstrated that these C-terminal tails determined the localization of the glutamate receptors. I also got beautiful ...
