a. Muscimol infusion locations (red crosses) near VM/VAL. Sites from left (n = 3) and right (n = 3) hemispheres were mapped onto the left hemisphere.
b. Small muscimol infusion (1.5-5 ng) near VM/VAL produced ipsilateral bias. Left, performance change in contra-trials after muscimol infusion. Right, performance change in ipsi-trials after muscimol infusion. Each line represents an infusion site (n = 6, same mice as in a). *, P < 0.05.
c. Muscimol infusion locations in the anterior part of the thalamus (red crosses). Sites from left (n = 2) and right (n = 2) hemispheres were mapped onto the left hemisphere.
d. Muscimol infusions in the anterior part of the thalamus (∼ 0.3 – 0.8 mm anterior to VM/VAL; same mice as in c). Note that much higher muscimol concentrations (10 times of those used near VM/VAL), did not affect behavior.
e. Muscimol infusion locations in the dorsal part of the thalamus (red crosses). Sites from left (n = 2) and right (n = 2) hemispheres were mapped onto the left hemisphere.
f. Muscimol infusions in the dorsal part of the thalamus (∼ 0.2 - 0.5 mm dorsal to medial dorsal thalamus, same mice as in e). Note that much higher muscimol concentrations (10 times of those used near VM/VAL), did not affect behavior.
