Excitatory neurons

Excitatory neurons are nerve cells that, when activated, increase the likelihood of their target neuron firing an action potential. They primarily release the neurotransmitter glutamate at their synapses. They form the primary driving force in neural circuits throughout the brain (e.g., cortical pyramidal neurons) and are fundamental for information propagation, synaptic plasticity (like LTP), and processes such as learning, memory, and cognition.
