Grey matter is primarily responsible for:

Grey matter is primarily responsible for:

• A. Conducting impulses along myelinated tracts
• B. Processing information
• C. Regulating blood flow
• D. Producing cerebrospinal fluid

Answer: (B)

Grey matter is where information processing and integration occur. It contains neuronal cell bodies, dendrites, and unmyelinated axons, and is concentrated in the cerebral cortex and deep nuclei. This cellular makeup makes it the primary site for processing sensory information, interpreting signals, forming memories, and planning motor responses after analysis. Conducting impulses along myelinated tracts belongs to white matter, which links grey-matter regions with fast signal transmission. Regulating blood flow and producing cerebrospinal fluid involve vascular/neural systems and the choroid plexus, respectively, rather than the processing role of grey matter.
