The studies I linked above started measuring 2-10 minutes after stunning, but there are other studies which have measured CNS activity before, during, and immediately after the stunning process—for example, Fregin & Bickmeyer (2016). Interestingly, they observed that before settling into a quiescent state, intense epileptic-form seizures occur in the CNS that last for up to an hour after stunning. In mammals, epileptic-form seizures are associated with a loss of consciousness and a lack of subjective experience during that period, suggesting insensibility (and this is roughly how the authors interpret their finding). However, more work needs to be done to better understand this phenomenon in decapod crustaceans.
I’m not focussing on the asphyxiation process, so I’ll let someone with more knowledge in that area chime in. If no one does, I’d be happy to look into it!
I see, thanks. Is it possible to measure spontaneous CNS activity from beginning to end of the stunning and asphyxiating process?
