摘要: Abstract Some methods of micro-electrode tip position marking are briefly discussed. Alcian blue, extruded iontophoretically with low current intensities (0.5 μA) and short time intervals (1–2 min) produces well-defined, non-fading spots in nervous tissue. We have succeeded producing 45 54 attempts.
