Is a synapse is the functional connection between two neurons?

Yes, a synapse is the functional connection between two neurons, allowing them to communicate with each other. It typically consists of a presynaptic neuron, which releases neurotransmitters, and a postsynaptic neuron, which receives these signals. This interaction is crucial for transmitting information throughout the nervous system. Synapses can be excitatory or inhibitory, influencing the likelihood of the postsynaptic neuron firing an action potential.
