A population of neurons in the principal somatosensory nucleus of human thalamus (ventralis caudalis, Vc) had a significant tonic, graded response to cool stimuli and also responded to innocuous mechanical stimuli (mechanical-cool neurons). These neurons were clustered at the dorsal aspect of medial Vc. Stimulation at the sites where these neurons were recorded evoked tingling sensations in the part of the body including or adjacent to the receptive field of these neurons. These neurons may contribute to the mechanism that mediates the perception of cold in man.
人类丘脑主要体感核（尾侧腹核，Vc）中的一群神经元对冷刺激有明显的紧张性分级反应，并且对无害的机械刺激也有反应（机械冷觉神经元）。这些神经元聚集在内侧Vc的背侧。在记录这些神经元的部位进行刺激，会在包括这些神经元感受野或其相邻部位的身体区域诱发刺痛感。这些神经元可能参与介导人类冷觉感知的机制。
