What it is and what it does
The cerebellum lies in the caudal part of the cranial cavity, above the brainstem, to which it is joined by peduncles; it has a median vermis and two hemispheres, with a surface furrowed into folia. It coordinates movement and balance. In awake dogs scanned with fMRI, its activation rose with the concentration of the odor; the authors link it to the control of sniffing and to the detection threshold.
Worth remembering
On fMRI, the awake dog's cerebellum responded to odor intensity; the hypothesis: it helps control sniffing.
Names
- Latin term: cerebellum.
- In Romanian: Cerebelul (Romanian page).
In the atlas lessons
The head: what you see, what is underneath (6 min):
Still in “Organs”: the brain, with the olfactory bulb at the front, the cerebellum and the brainstem at the back, the pituitary underneath. The path of a scent continues in “Journey of a scent”.
The brain and scent: where the trail ends up (7 min):
The cerebellum coordinates movement; in awake dogs, its activation rose with odor concentration (Jia 2014). The brainstem carries the cranial nerves, including the facial nerve, which moves the lips and the ears.
