Figure 4From: Synaptically evoked glutamate transporter currents in Spinal Dorsal Horn Astrocytes Glutamate transporter current in spinal astrocytes is abolished by blockade of synaptic transmission. Bath application of 40 μM CdCl2 (n = 3, A) or 1 μM TTX (n = 4, B) inhibited the evoked glutamate transporter current in spinal astrocyte, indicating the synaptic origin of these currents.Back to article page
