  • As someone who also works in the neuroscience field and is somewhat sympathetic to the Gibsonian perspective that Chemero (mentioned in the essay) subscribes to, being able to decode cortical activity doesn’t necessarily mean that the activity serves as a representation in the brain. Firstly, the decoder must be trained and secondly, there is a thing called representational drift. If you haven’t, I highly recommend reading Romain Brette’s paper “Is coding a relevant metaphor for the brain?”

    He asks a crucial question, who/what is this representation for? It certainly is a representation for the neuroscientist, since they are the one who presented the stimuli and are then recording the spiking activity immediately after, but that doesn’t imply that it is a representation for the brain. Does it make sense for the brain to encode the outside world, into its own activity (spikes), then to decode it into its own activity again? Are we to assume that another part of this brain then reads this activity to translate into the outside world? This is a form a dualism.



  • I live in China (Hangzhou, actually). Just to add to what people have already said. WeChat now accepts international credit/debit cards and it works fairly reliably now (my girlfriend recently visited and she was able to use both WeChat and AliPay), but I think AliPay is probably more reliable. I’m fairly confident they both would work in Guilin/Changsha, but bring cash just in case.
