While some were quick to point out that this was proof of an ethereal soul, and others said that the dish was still “thinking” after death, researchers who made the report public say that neither is the case. Rather, they argue, this study was done as a reminder to colleagues in the scientific community of the dangers accompanying fMRI-survey interpretation, LiveScience reports. fMRI technology allows experts to essentially keep track of blood-flow patterns inside the brain. While this is an extremely useful ability for scientific studies, it can also lead to a number of “false positive” results that can taint the investigation. Misleading results, published in important journals, can also influence policymakers, and perpetuate changes that are, in fact, neg!
ative to the very people they were supposed to serve. The results of the new investigation, showcased at a scientific conference earlier this year, show that the fish's brain did not behave in any abnormal ways, and that its actions can be thoroughly explained scientifically. “The goal of the salmon pos...
