HSR-2025 science biology behavioralscience invertebrates HSR questions potential research idea

  • He adds that he doubts that the findings are applicable to other insect species, which still might act purely on instinct.
  • Invertebrate nervous systems, physiology, and sensory experiences are dissimilar to ours, and designing experiments to measure their emotions has been challenging. 
  • If the responses weren’t purely reflexive, it would open up the possibility that the animals could feel pain.

  • After placing acetic acid—a mild irritant—on the crabs’ antennae, they found that the crabs rubbed their antennae against the glass of their aquarium, seemingly in an attempt to take the acid off.

      The use of an invisible irritant rather than a notable injury shows that they can feel the pain, instead of just noticing an injury to their body.

  • In addition, due to its low toxicity to fish, prometryn can be applied directly to aquatic activities for the removal of harmful algae and weeds in aquaculture waters

Sean Nash liked it
  • how they provided guidance on general methods that could be applied to other animals such as decapod crustaceans.
  • indicate that responses of both go beyond those expected of mere nociceptive reflex.

      Where is the limit between a reflex and a cognitive response?
  • Sean Nash on 01 Jul 24
     
    I really like this topic, and it is one that is getting some current attention. so, we obviously cannot discern cellular-level factors with the nervous system of animals (and obviously- especially when dealing with pain response, we would have to work exclusively with invertebrates and the experimental design would have to be very well thought out. That said, behavioral studies where you have a really tight experimental design set up.... and you're recording behavioral changes... is likely feasible. If this is interesting, keep digging into pain vs. reflex studies, and also begin to look at invertebrate models that we can both successfully raise... and that have interesting behavioral responses we can readily discern in the lab.

    Two reasons to like this one... both invertebrates & learning/behavioral science tend to be feasible areas for research at our level. Keep reading... more deeply AND more broadly.
