Figure 1. — Effects of somatosensory thalamus or superior colliculus lesions on detection of a low salience WCS. A, Effect of sham injection (SHAM) on performance in the High/Low active avoidance task. Four groups are shown in pairs of data points. The first data point refers to 20 trials collected before SHAM injection. The second data point refers to 20 trials collected after SHAM injection. Note the decrease in task performance during the Low salience WCS trials and the lack of effect of the SHAM procedure on task performance. B, Effect of TTX inactivation (TTX) on performance in the High/Low active avoidance task. Data are shown as in A. Note the selective decrease in task performance during Low salience WCS trials as a consequence of the inactivation of the somatosensory thalamus or superior colliculus.
