Axons have traditionally been regarded as simple cables for the stable transmission of action potentials. But recent data indicate that the functional capacity of axons is much more extensive and ...

Figure 1: Afterhyperpolarization at the calyx reduces the Prob AP at the axon. The afterhyperpolarization also occurred after trains at 10–20 Hz (20–100 action potentials; Fig. 1i), which could also ...

Voltage-gated calcium channels swing open with passing action potentials, allowing calcium ions into the cell, and slide shut when the membrane depolarization has passed. Two papers this month suggest ...

Changes to the microtubule-binding protein tau cause it to fall off these struts and aggregate, forming neurofibrillary tangles. But is that the reason for tau toxicity? A study in the September 18 ...
