Inside the brain is a dense network of neurons that receive, process, and relay information. The synapse, where neurons meet, ...

National Institutes of Health researchers have mapped how individual neurons in the primary somatosensory cortex receive brain-wide presynaptic inputs that encode behavioral states, refining our ...

Many types of neurons can release endocannabinoids that act as retrograde signals to inhibit neurotransmitter release from presynaptic terminals. Little is known, however, about the properties or role ...

In the mammalian brain, synaptic transmission usually depends on presynaptic action potentials (APs) in an all-or-none (or digital) manner. Recent studies suggest, however, that subthreshold ...

Neurons send signals to each other across small junctions called synapses. Some of these signals involve the flow of potassium, calcium and sodium ions through channel proteins that are embedded ...

As spindly, elongated cells, neurons must be able to transport proteins and receptors between distant sites in their cell bodies and axons to function properly. A new imaging study by researchers at ...
