When neuroscientists analyzed the exact properties of nerve connections in the brain, they made a startling observation: At a key connection, or synapse, messages are sent against the usual stream of ...

BIN1, one of the strongest genetic risk factors for late-onset Alzheimer’s disease, encodes a protein that dabbles in many cellular functions, taking a hand in Aβ production, tau propagation, and ...

How do we think, feel, remember, or move? These processes involve synaptic transmission, in which chemical signals are transmitted between nerve cells using molecular containers called vesicles. Now, ...

(1) A nerve impulse arrives. (2) This causes calcium ion channels to open, resulting in an influx of calcium ions in the terminal. (3) This causes synaptic vesicles to fuse with the terminal membrane, ...
