Shootin1a—the missing link underlying learning and memory

In neurons, changes in the size of dendritic spines—small cellular protrusions involved in synaptic transmission—are thought to be a key mechanism underlying learning and memory. However, the specific way in which these ...

Synaptic transmission: Not a one-way street

Information flows in a well-defined direction in the brain: Chemical and electrical signals are passed from one neuron to the other across the synapse, from the pre-synaptic to the post-synaptic neuron. Now, Peter Jonas and ...
