Excitatory Synapses

Excitatory synapses are connections between nerve cells that increase the likelihood of a signal being passed from one neuron to another. When an excitatory neurotransmitter is released from the sending neuron, it binds to receptors on the receiving neuron, causing changes that make it more likely to "fire" and send its own signal. This process is essential for communication within the brain, influencing everything from muscle movement to mood and cognition. In summary, excitatory synapses play a crucial role in enhancing neuronal activity and facilitating the flow of information in the nervous system.
