The temperature sensitivity of the Type I slowly adapting mechanoreceptors in cats and monkeys

摘要: 1. The sensitivity of Type I slowly adapting mechanoreceptors in cat and monkey skin to temperature changes was investigated.2. Multiple receptors innervated by a single axon appeared be more frequent the than skin.3. responses these thermal stimulation at static temperatures from 27 40 degrees C were similar cats monkeys. At 43 showed higher steady-state activity receptors.4. A maximum frequency 5.5 impulses/sec occurred both 37 C.5. dynamic response cooling C. near its 2 increased but little with further increases intensity cooling.6. Dynamic disappeared after had been heated 51 for 35 sec mechanical heating 53 sec. Excitation either or did not reappear within 1-2 hr.7. characteristics differ those specific cold receptors.
