Figure 3From: Protein phosphatase 2A regulates central sensitization in the spinal cord of rats following intradermal injection of capsaicinEffect of the PP2A inhibitor, okadaic acid (OA, 20 nM) on exploratory activity of rats during a consecutive period of 45 minutes (9 intervals, 5 min/interval). Compared to the intrathecal catheter implanted rats (n = 14), pretreatment with OA through an intrathecal catheter (n = 7) did not produce significant alterations in exploratory activity.Back to article page
