Summary
The effects of hypocalcemia induced by excision of the parathyroid glands upon the function of spinal motoneurones and peripheral receptors were investigated in decerebrate cats.
1. In hypocalcemic convulsions the motoneurones show extraordinary high frequency discharges.
2. Both alpha and gamma motoneurones often exhibit double discharges, “doublets”.
3. The peripheral receptors, for example those in muscle spindles, have bursts of high frequency impulses “multiplets”; these are obtained with and without efferent muscle innervation.
4. The relation of this hypocalcemic excitation of the receptors to the changes in perception, spinal reflexes, and the neural control of respiration is discussed.
