Ischemia-induced inward currents in spinal cord dorsal horn neurons of rats at different ages. A). Three sample traces show inward currents induced by ischemia in dorsal horn neurons from rats at the age of 6 days old (top trace), 10 days old (middle trace), and 20 days old (bottom trace). The horizontal bar above the traces indicates the time period when ischemia bath solution was perfused to the spinal cord slice preparations. B). The relationship between ages of rats and onset time of ischemia-induced inward currents. Numbers above the curve indicates the number of animals. All recordings were made from lamina V dorsal horn neurons.
