In the orchestra of the brain, the firing of each neuron is controlled by two notes—excitatory and inhibitory—that come from two distinct forms of a cellular structure called synapses. Synapses are essentially the connections ...

A McGill-led multi-institutional research team has discovered that during memory consolidation, there are at least two distinct processes taking place in two different brain networks—the excitatory and inhibitory networks. ...

Brain function depends on inhibitory cells that balance or 'brake' excitation. These neurons allow the brain to process information and also prevent runaway seizures. A new study from the George Washington University (GW), ...

Think about traffic flow in a city—there are stop signs, one-way streets, and traffic lights to organize movement across a widespread network. Now, imagine what would happen if you removed some of the traffic signals.

Neurons pass on information to one another via synapses. The vast majority of these synapses are excitatory, which increase the activity of the receiving neuron. Around 10 to 20 percent of synapses have the opposite effect, ...
