Hippocampal levels and activity of the sodium/potassium transporting ATPase subunit alpha-3 (AT1A3) are paralleling memory training in the multiple T-Maze in the C57BL/6J mouse

► Hippocampal sodium-potassium transporting ATPase levels are paralleling spatial memory training. ► Hippocampal sodium-potassium transporting ATPase activity is paralleling spatial memory training. ► The enzyme driving the electrochemical gradient in the hippocampus is increased during memory formation.
