Viruses are not composed of cells and are therefore non-living. Receptors respond to stimuli and send nerve impulses along sensory neurons. I don’t disagree at all though that this study is by no means a conclusive look at the crow brain during these experiences, and I’m not sure how I could have made that more clear to you in the article. Just saw a clip of your research on youtube. As a result of cold, winter weather (stimulus) some animals will hibernate.

So instead, our team used a different kind of non-invasive imaging technique to spy on the minds of crows: FDG-PET. If the Bald Eagle gets to cold it will usually migrate south to get to hotter and milder weather. Back then in 1980 they didn’t spay or neuter cats but rather euthanized them after rounding them up.

When plants respond to external stimuli it is called tropism. In most animals this job is done by the central nervous system (CNS). She’d never forgotten it. The animal can then be anesthetized and placed into a PET machine where, via a mechanism involving photons and gamma rays that was far too complex for me to bother retaining beyond my graduate exams, the machine can detect the tracer. In fact that’s a really interesting case study of an old Parkinson’s drug causing gambling addictions specifically because it tapped into these systems in ways they hadn’t previously understood. One came last year that repeatedly said what sounded like “Bobby” and would respond if repeated back. When I was a student at the University of Alberta up here in Canada I saw a very eerie sight.

A taxis – is a directional response of a whole organism to a stimulus. Certain behaviors, such as mating or nesting, are responses to pheromone stimuli. Where do you reckon this idea stems from? When the temperature begins to dip, the Red Panda grows a thick fur in order to keep them warm. Hey they’ll be good company since we’re all self isolating anyway, right? Also see: What Is The Reason Plants Transport Water Against The Force Of Gravity? I don’t look to my cat or other animals for moral guidance. Just before the sun rises in the morning, they’ll feel a biological urge to crow in response to their biological clock. Unlike fMRI which tracks real-time blood flow, FDG-PET tracks metabolic activity and most importantly it can do so retroactively. Living things are capable to rapid changes in the environment. Elwood, Robert W. (2020) Do arthropods respond to noxious stimuli purely by reflex?. African Dwarf Frogs are social animals, so they are best kept in groups of two or more.

For greater distances, the response consists of a forward hop whose amplitude also varies with stimulus distance. So while you scoff at the idea we could ever look to the brain to tell us anything about emotion, know that we have and are already doing that in humans and it has lead to crucial improvements in treating emotional disorders like PTSD.
