FIG. 5.

SI vs. RC. The relationship between angular tuning SI and trial-by-trial RC for nonadapted simultaneously recorded neuron pairs: cortex time window 5–25 ms after stimulus onset (A); thalamus time window 4–24 ms after stimulus onset (C); early thalamic response time window 4–9 ms after stimulus onset (E). Note that these relationships are significant (P < 0.01), but weaker than for pairs of trigeminal ganglion pairs. The stimulus dependence of response covariation is maintained after adaptation: barrel (B), thalamus (D), early thalamic response (F).
