A new study has revealed how tau – a microtubule-binding protein that is implicated in Alzheimer’s disease – weakens transmission across synapses in the brains of mice When injected into presynaptic ...

(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, ...

Neurons can rapidly rebalance their communication using a structural signal rather than electrical activity, overturning long-held assumptions about how synapses maintain stability.

The human brain contains nearly 86 billion neurons, constantly exchanging messages like an immense social media network, but neurons do not work alone – glial cells, neurotransmitters, receptors, and ...
