Are Relay neurones inhibitory or stimulatory?

Relay neurons, also known as interneurons, can be either inhibitory or excitatory depending on their specific function and the neurotransmitters they release. Inhibitory relay neurons typically release neurotransmitters like gamma-aminobutyric acid (GABA), which reduce the likelihood of action potentials in target neurons. On the other hand, excitatory relay neurons release neurotransmitters like glutamate, which increase the likelihood of action potentials. Thus, the role of relay neurons is context-dependent within neural circuits.
