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."
Discussion¶
Related Claims¶
- A biophysical model suggested that more excitable LA neurons are preferentially recruited into the fear memory trace via competitive synaptic interactions, validated experimentally — related
- A biophysical LA model showed both auditory thalamic plasticity and intra-amygdala plasticity contribute to fear memory, with thalamic responsiveness essential during learning but dispensable after training — related
