What factors limit the minimum diameter of an axon? And what is that minimum diameter? Faisal and colleagues used biophysical theory and stochastic simulations to investigate these questions, and ...

WOODS HOLE, Mass. -- In a provocative new study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit ...

Axons are the brain’s information highways, transporting cellular cargo, chemical signals, and electrical impulses to other cells. These “roads” are typically depicted as smooth and cylindrical, with ...

Axon potentials recorded in somata of pyramidal neurons in vivo have a fast rising phase and variable threshold, contrary to predictions of the Hodgkin¨CHuxley model. Some have suggested that this ...

Axons surrounding amyloid plaques swell, but what goes wrong inside, and with what consequences, remains murky. Using high-resolution imaging techniques, scientists led by Jaime Grutzendler at Yale ...

A team of scientists at Harvard Medical School (HMS) has identified a new mechanism of dopamine release in the brain in a study conducted in mice that was published in the journal Science (“An action ...
