本文在大鼠脑干组织切片（400-500μm）上研究了中缝核神经元的温度敏感性。在中缝背核区域的单细胞活动的测量表明，大多数神经元（89%）是敏感的温度变化。在34 ~ 42 °C温度范围内，发现3类温度敏感细胞：温型（61%）、冷型（15%）和双相型（13%）。许多中缝背核神经元可能具有内在的温度敏感性，并可能在中枢温度调节的整合过程中作为下丘脑外温度检测器的组成部分。
Thermosensitivity of raphe neurons was studied in tissue slices of rat brainstems (400–500μm). Measurement of activity of single cells in the dorsal raphe region of the slices revealed that the majority of neurons (89%) were sensitive to changes in temperature. Over the range 34 to 42 °C, 3 classes of thermosensitive cells were found: warm (61%), cold (15%) and biphasic type cells (13%). Many dorsal raphe neurons may be intrinsically temperature sensitive and may serve as extrahypothalamic thermodetector components in the integrative process of central thermoregulation.
