A controversial idea from the mid-20th century is attracting renewed attention from researchers developing theories for how cognition arises with or without a brain.

Neural connections in the mouse neocortex can release multiple packages of neurotransmitters per electrical impulse, a study finds.

Synapses in the mouse neocortex can release multiple packages of neurotransmitters, suggesting that connection strength is more flexible than previously thought.

The method combines two approaches to reveal a high-resolution map of all 40 million synapses.

The flow of calcium and potassium ions keeps muscles contracting in the diaphragms of neonatal mice, but if a key protein receptor is missing, fatigue sets in more quickly.

A new study reveals more about the role of specialized Schwann cells at junctions between neurons and muscle cells.

A new technique reveals certain neuronal connections grow larger and denser when memories are made.

To chew up waste in far-reaching dendritic spines, lysosomes are trafficked sometimes hundreds of microns away from the cell bodies of neurons in rats. 

Ben Barres recast glial cells from supporting actors to star performers, crucial for synaptic plasticity in the brain and for preventing neurodegenerative disorders.
