What I like about this & the Whishaw chapter that’s been rediscovered is that it shows there are the rich sensory signals running through subcortical areas are clearly sufficient for many complex, proactive actions.
What can cats do without cortex? "The animals presented a rich behavioural repertory. They could not be distinguished from normal litter mates when young...The behaviour was like that of a phylogenetically older species and reminded us of a large lizard we keep in a terrarium"https://twitter.com/AndrejBicanski/status/1072105327179517952 …

yeah I do think a lot more behavior is subcortical than grad students is canonically taught cortex = refinement/subtle variations, complex pattern recognition that have little effect in macro sense but big effect in fitness sense?
-
I want to see these behavior classification algorithms run on decorticated animals
-
How hard would it be to rig up reversible opto-decortication do you think?
-
Pretty easy. We have 3 rigs in our lab. Polished dental acrylic gives long-term optical access to most of cortex in VGAT-ChR2 mice. Optical control hardware <$2k for whole cortex, <$10k for targeted random access. https://www.ncbi.nlm.nih.gov/pubmed/24361077 pic.twitter.com/yK0vBFmbMV

Great! Now folks can start working on the behaviors that are cortically dependent
-
is there a review/list somewhere of behaviors that are expected/known to be cortically-dependent?

An
#evergreen question in my#affectiveneuroscience course: What can rats do without a cortex? (tl;dr: quite a bit)Thanks. Twitter will use this to make your timeline better. UndoUndo

ah the good old days "...these kittens did not survive the period just after the operation although various types of anaesthesia and postoperative treatment were tried."

interesting that it lost its cute.

Less refinement of behavior due to reduced self-feedback?
