Fear learning induces synaptic potentiation between engram neurons in the rat lateral amygdala

LA (lateral amygdaloid nucleus) UBERON:0002886 functionally connects to Rat lateral amygdaloid nucleus principal neurons nt-gypnv5m278 · Rat

Among inhibitory neurons tagged as recruited after fear conditioning, 4 of 18 made local connections onto nonrecruited LA pyramidal neurons. All of these connections were inhibitory, producing IPSPs.

Made by an AI model reading the paper (claude-opus-5-5, extract@0.3.0); a second AI model (claude-opus-5-5) disagrees. “The paired recordings support inhibitory connections from 4 of 18 recruited interneurons onto non-recruited pyramidal neurons, but 0.222 is the share of interneurons making any connection, not a per-pair connection probability as this paper defines it.”
