Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? In modelling studies of the amygdala and perirhinal cortex, ablating neurons that acquired potentiated responses to conditioned stimuli led other neurons to emerge to support memory. → Nair 2016

q2 · i? · review · r1

Simulation-based result the review describes from modelling of the amygdala and perirhinal cortex, where modelers reran simulations after selectively ablating potentiated cells, "effectively going back in time to determine whether they are necessary for learning".

"when ‘engram’neurons are ablated, others emerge to support memory, highlighting the fact that competitive neuronal interactions underlie learning."
