Differential localization in dorsal funiculus of fibres originating from different receptors

Experimental Brain Research Aims and scope Submit manuscript

Summary

The cervical part of the dorsal funiculus in the cat was investigated by recording from single fibres and by recording of mass activity in dissected fascicles. It is demonstrated that large myelinated fibres originating from different receptors ascend at different depths of the funiculus. Fibres from hair and claw receptors occupy the superficial part of the funiculus and fibres from touch and vibration receptors the deep part. Fibres from muscle receptors occur at an intermediate depth of the funiculus. A large number of synaptically activated fibres ascend in the deep part.
