The lateral microtubule-containing neurons run like this on each side. [See Figure 1] Destruction of the anterior/posterior pair with the laser microbeam greatly reduces anterior/posterior touch sensitivity (assayed by stroking lightly with a mounted eyebrow hair). Destruction on just one side does not give consistent results. Destruction of other neurons has not given reproducible loss of touch sensitivity so far. The collection of touch insensitive (tin) mutants suffered in the great thaw of '75, but thanks to multiple isolates all but one of the original eight genes are still represented. Nomarski shows:- in tin-1 V and tin - 3 IV the processes and cell bodies of the microtubule neurons are absent or displaced; in tin - 2 X the processes are normal but the cell bodies are disoriented; in tin - 4 X, tin - 6 I and tin - 7 X both appear normal.
