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 ...

Let's think for a second about thought—specifically, the physics of neurons in the brain. This topic has been the lifelong interest of Jose Rizo-Rey, professor of Biophysics at the University of Texas ...

The activity of neurons in the mammalian brain has been found to be linked with various physiological processes, including the flow of blood that provides them with the energy required to function ...

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, ...
