What happens if two neurons touch?

When two neurons come into close proximity, they do not physically touch; instead, they form a synapse, a specialized junction where communication occurs. At the synapse, the sending neuron releases neurotransmitters that cross the synaptic cleft and bind to receptors on the receiving neuron, facilitating signal transmission. This process is crucial for information processing in the nervous system, enabling the transfer of signals that can influence behavior, thoughts, and bodily functions. If neurons were to directly touch, it could disrupt this delicate signaling process and potentially lead to dysfunction.
