Figure 2.
Number of counterclockwise circles (A) and rears (B) observed immediately after single or repeated insertions into the 14.1 T magnet. Rats were either sham-exposed (white bars) or inserted into the magnet (black bars) once for 30 min, or rapidly inserted and removed from the magnet 5 times (5x/0min), or inserted and removed 5 times over the course of 30 min (5x/sham, 5x/30min). Circling was only observed after 30-min magnet exposure regardless of number of insertions. Rearing was suppressed in all magnet-exposed groups* p < 0.05 vs. 1x/sham; † p < 0.05 vs. 5x/0min.
