MD (Mediodorsal nucleus of thalamus) functionally connects to ACA (Anterior cingulate area)

Halorhodopsin inhibition of MD axon terminals in the ACC, applied during the demonstrator's foot shocks, removed the shock-related calcium responses in nearly all ACC shock-responding cells imaged in observer mice.

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 96.4% figure is the share of shock-responding cells whose response was suppressed during terminal inhibition, not a connection probability, so the number is mislabelled.”
