Meaning and Definition
The part of the brain associated primarily with the sense of smell.
In neuroanatomy, the rhinencephalon originally referred to the olfactory lobe and its associated structures in the forebrain, but its definition has evolved. In modern usage, it is often used synonymously with the 'olfactory brain' or the limbic system structures that are phylogenetically old and involved in olfaction, emotion, and memory.

Frequently Asked Questions
No, it is a highly specialised term used almost exclusively in neuroanatomy and related scientific fields.
Its primary historical function is olfaction (smell), but it is also linked to aspects of emotion and memory as part of the limbic system.
Yes, but in humans it is relatively small compared to other mammals and is integrated into the limbic system rather than being a distinct 'smell brain'.
The rhinencephalon is an older term focusing on olfactory structures. The limbic system is a broader, more modern concept encompassing those structures plus others involved in emotion, behaviour, and memory.
The part of the brain associated primarily with the sense of smell.
