Cortical representations of affective pain shape empathic fear in male mice

ACA (Anterior cingulate area) MBA:31 projects to PAG (Periaqueductal gray) MBA:795 · Mouse

Injecting retrograde AAV-Cre into the right PAG, combined with Cre-dependent GCaMP8f in the right ACC, labelled ACC neurons that project to the PAG; 312 such neurons were imaged across 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) agrees.

ACA (Anterior cingulate area) MBA:31 projects to BLA (Basolateral amygdalar nucleus) MBA:295 · Mouse

Retrograde AAV-Cre injected into the right BLA, with Cre-dependent GCaMP8f in the right ACC, labelled BLA-projecting ACC neurons; 280 of these cells were imaged.
