Wait, I may need to amend my previous post. Exactly what human faces were shown to the dead salmon?Ygggdrasil said: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? :)BillTre said:Short Science mag news story here.
Brain scans similar to humans.
It took me WAY too long to decode what you were asking.Greg Bernhardt said: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.Ygggdrasil said: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:

There are a few signs that can indicate whether or not your dog enjoys it when you smile at them. These include their tail wagging, relaxed body language, and possibly even a smile back at you.
Yes, it is believed that dogs can recognize human facial expressions, including a smile. This is because they are highly attuned to our emotions and body language.
Yes, smiling at your dog can help strengthen your bond. Smiling releases feel-good hormones in both humans and dogs, and your dog may associate your smiling face with positive experiences and emotions.
Looking away can be a submissive gesture in dogs, so your dog may be trying to show you respect or avoid conflict. It could also be a sign of anxiety or discomfort.
While smiling at your dog can have positive effects, it's important to pay attention to your dog's body language and respect their boundaries. Some dogs may not like direct eye contact or may interpret a smile as a sign of aggression. It's always best to let your dog approach you for affection and respect their personal space.
