researches placed a dead salmon from the supermarket into an fMRI scanner and, using the same analysis techniques used in many published papers, found signs of activity in certain regions of the brain when showing the salmon pictures of human faces.
Wait, I may need to amend my previous post. Exactly what human faces were shown to the dead salmon?researches placed a dead salmon from the supermarket into an fMRI scanner and, using the same analysis techniques used in many published papers, found signs of activity in certain regions of the brain when showing the salmon pictures of human faces.
With or without teeth? :)Short Science mag news story here.
Brain scans similar to humans.
It took me WAY too long to decode what you were asking.With or without teeth? :)
Now that hurts Yggg! I know my recently deceased dog, Ming, would respond to me smiling by waging his tail. Maybe dead salmon have superpowers we just don't know about yet. Ok, I will temp ban myself now.It should be noted that functional magnetic resonance imaging (fMRI), the technique that the study is based on, have been notoriously unreliable and subject to many false positive. For example, to demonstrate the ease of discovering false positives, researches placed a dead salmon from the supermarket into an fMRI scanner and, using the same analysis techniques used in many published papers, found signs of activity in certain regions of the brain when showing the salmon pictures of human faces. Furthermore, fMRI is a very indirect measure of brain activity, measuring things like increased blood flow or increased metabolic activity in different areas of the brain. To what extent these observables correlate with the underlying activity of neurons is still unclear.
Here's a nice piece from a few years ago highlighting some of the issues with fMRI and other similar brain scans:

Definitely a picture set up with a trained salmon.Wait, I may need to amend my previous post. Exactly what human faces were shown to the dead salmon?
