Summary Introduction
Introduction:
The thalamus is a dorsal part of the forebrain or diencephalon that consists of a major part of the gray matter in the brain. This structure regulates the sleep and maintains consciousness and alertness. It also relays sensory information to its concerned cortical region. The anterior nuclei are a cluster of nuclei present in the dorsal thalamus.
