Local Cerebral Blood Flow During Hibernation, a Model of Natural Tolerance to “Cerebral Ischemia” Kai U. Frerichs, Charles Kennedy, Louis Sokoloff and John M. Hallenbeck [ originally published in Journal of Cerebral Blood Flow and Metabolism 1994;14(2):193–205] The weighted average cerebral blood flow in the brains of hibernating and nonhibernating ground squirrels appeared in three places in the article cited above. The numbers varied to some extent in each of the three places that they were displayed. The correct number for the active ground squirrel group was 62 ± 18 ml 100 g−1 min−1. The correct number for the hibernating group was 7 ± 4 ml 100 g−1 min−1. These numbers should be inserted on page 193 in the abstract so that the sentence would read, “Mean (± SD) mass-weighted CBF in the brain was 62 ± 18 ml 100 g−1 min−1 (n = 4) in the control group but was reduced to ischemic levels, 7 ± 4 ml 100 g−1 min−1 (n = 4), in the hibernating animals (p < 0.001).” The same numbers should be inserted into the sentence that begins at the bottom of page 198, “Average blood flow (± SD) in the brain as a whole in the hibernating animals was reduced to about 1/10 (7 ± 4 ml 100 g−1 min−1) of the level in active animals (62 ± 18 ml 100 g−1 min−1) (Table 4).” Finally, on page 201 at the bottom of Table 4 below “Weighted average in brain as a whole,” the readings should be 62 ± 18 for active and 7 ± 4 for hibernating.
