N Figure 1. Nervous System Hierarchy Characteristics of the Central Nervous System The most fundamental way of categorizing groups of neurons that make up the central nervous system is as nuclei and Persistant viral infections of the central nervous system. Genomes either integrate or persist as episoms. Mechanism of persistance is not yet understood. Avoid detection and elimination by the host.
