**Key Considerations When Choosing:**

* **Blog Content:** Choose the description that best reflects the style and content of your blog.
* **Audience:** Consider the target audience and their level of understanding.
* **Keyword Density:** While not as critical for tags as for post titles, consider using related keywords.
* **Length Limits:** WordPress has no specific length restrictions for tag descriptions in recent versions, but keep it concise.
* **SEO:** Tags are less important than titles and the post content in affecting SEO, but a short, descriptive tag description can offer a help.

**Recommendation:**

For a general WordPress blog, I’d recommend **Option 2** or **Option 3** as a starting point, as they strike a good balance of information and accessibility. If your blog specializes in a narrow aspect of the nervous system, using **Option 4** is advisable.
