I’m sure that you would like to improve on this terrible pun–feel free to chime in in the comments! And now let’s move beyond the acronym: this post is about a poster that was shown at #SfN14 on Monday morning, November 17, during the session on Executive function: Decision making.

358.21/SS34. Disrupting inhibition in posterior parietal cortex reduces decision accuracy. K. ODOEMENE, A. M. BROWN, M. T. KAUFMAN, A. K. CHURCHLAND

The authors, from Cold Spring Harbor Laboratory, NY, are interested in understanding how sensory information is used by the brain to inform decision making. They trained mice on a visual discrimination task in which the animals had to learn to recognize that a slowly flashing light was associated with a water reward in one location and a faster flash with a reward at another place.
