Here's why:

* Intrinsic neurons: This term emphasizes that these neurons are found entirely within a particular structure (like the spinal cord or brain region). They are not projecting to other parts of the nervous system like motor or sensory neurons.

* Local circuit neurons: This term highlights their role in local processing and communication within a specific region. They connect neurons within that region, creating complex circuits for information processing.

It's important to note that while "interneurons" is the most common term, "intrinsic neurons" and "local circuit neurons" are used interchangeably and convey the same essential meaning.
