V3

visual area 3, which in primates is located in the prestriate cortex anterior to V2, from which it receives signals. It is specialized for monochromatic pattern perception. The ventral region is also referred to as area VP (ventral posterior area), whereas the dorsal region is often divided into two regions, V3a and V3b. The relationship among these three aspects of V3 is not fully understood.

herpetic neuralgia

pain associated with shingles, caused by reactivation of the herpes varicella-zoster virus (see herpes infection). Following an attack of chicken pox, the virus lies dormant in a dorsal nerve root and ganglion of the spinal cord; when reactivated, it spreads down the sensory nerve, causing vesicle formation and severe, burning, lancinating pain. This acute pain typically resolves in 3 to 5 weeks, but patients often develop the chronic, debilitating pain known as postherpetic neuralgia.
