Termination patterns of identified group II and III afferent fibres from deep tissues in the spinal cord of the cat.


In chloralose-anaesthetized cats, the impulse activity of single afferent fibres supplying receptors in the deep tissues of the hindlimb (fasciae, muscles, ligaments, joint capsules) was recorded using micropipettes filled with a solution of horseradish peroxidase. Only myelinated fibres with conduction velocities up to 40 m/s (Group III and Group II units… (More)
