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 ...
Nerve terminals are generally considered to be the destination points for electrical signals, which propagate unidirectionally from the soma to nerve terminals. We found that small hyperpolarizations ...
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 ...
