Comparison of Thalamic Discharges to the 1^st and 2^nd Formalin Induced Nociception.

Baseline is the spontaneous neuronal activity before formalin injection. Neuronal response after formalin injection is divided into phases based on changes in the behavioral pain responses. N = 19pairs of neurons from5 mice. All values are mean±SEM. FR: firing rate, ratio: % of respective firing modes from the total number of spikes.
