Nerve cells in the brain establish connections or synapses to form complex electrical circuits that keep people thinking and moving. Despite the importance of these synapses in mediating the flow of ...

Researchers discover that rare axo-axonic synapses form a decentralized network of "broker" neurons to drive split-second fly ...

Electrical synapses containing Connexin 36 (Cx36) represent the main means for direct electrical communication among neurons in the mammalian nervous system. However, little is kn ...

Schematic representation of axonal transport vesicles (blue) carrying presynaptic proteins (SV and AZ proteins). Kinesin motor proteins (KIF1A) attach these vesicles and carry them along the axons to ...

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight ...

When a person thinks, speaks, eats, walks, or just sits comfortably with all bodily systems functioning normally, the billions of cells that make up the brain and the rest of the nervous system are ...

A new PET tracer can provide insights into how spinal cord injuries affect not only the spinal cord, but also the brain, according to new research published in The Journal of Nuclear Medicine. By ...
