This important study leverages the power of Drosophila genetics and sparsely-labeled neurons to propose a new model for neuronal injury signaling. The authors present convincing evidence to support ...

Lichtman and colleagues have visualized the degradation of axonal fragments during synapse elimination. Previous studies of fluorescently labelled motor axons identified a trail of fluorescent ...

The three best examples of ion channel/receptor clustering in the nervous system are found at the synapse, the node of Ranvier, and the axon initial segment (AIS). In the case of the synapse, the ...

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 ...

Central to this activity are synapses, the junctions where branches of neurons connect, similar to electrical wires. Here, an axon from one neuron links to a dendrite of another. At these synapses ...

For more than a century, axons — the slender arms of brain cells — have been depicted as uniform tubes. These structures are responsible for transmitting information across neurons.

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 ...

An electrical impulse cannot directly cross the gap so a different mechanism has to be used. Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent ...
