Information can be conscious or unconscious.
The vertebrate nervous system develops from the hollow neural tube. The cerebral cortices are important in higher level brain functions many of which are conscious. The diencephalon consists of the thalamus and hypothalamus. The thalamus is a major relay station for information going to the telencephalon. The hypothalamus is important in regulating many physiological functions and biological drives.
