vestibular senstation
-
-

processing:
- projecting to nuclei in medulla and pons (hindbrain)
- also reach cerebellum
somatosensation
skin receptor sensitivity to different stimulus:

AB fibres (discriminative touch)
- Fast conducting
- object rek, iden
-
C-tactile afferents:
- slow conducting
- social touch
- HAIRY SKIN
