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.
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 ...
But something more sinister is happening deep in the tissue. The brain's motion is stretching and ripping your axons apart. If this sounds bad, you're right! Axons are delicate fibers that carry ...
The recent identification of ion-channel subtypes and ion transporters on the myelinated axon has allowed the characterization ... MRI reveals how the patient's brain partially compensates for ...
