Distinct visual pathways of threat retrieval in fear-conditioned faces www.biorxiv.org/content/10.64898/2026.03...

Distinct visual pathways of threat retrieval in fear-conditioned faces Numerous studies have demonstrated rapid (< 100 ms) visuo-cortical differentiation of threat-associated faces. This may be due to low-spatial frequency (LSF) visual information originating from magnocellular pathways. Yet it remains unclear whether potentially magnocellular fear signals extend beyond evolutionarily prepared emotional faces and whether they are subject to short-term neuroplasticity. If so, spatial frequency characteristics should modulate processing of faces with newly acquired threat-relevance. Furthermore, it is unknown whether sub-bands of the visual spectrum are associated with autonomic arousal. Using a differential fear-conditioning paradigm, this study tested whether early visual attentional capture, indicated by the P1 event-related potential component, prioritizes LSF information of threat-associated faces with neutral expressions. Additionally, it was tested whether such effects would be paralleled by threat signals in the skin conductance response (SCR). For contingency aware participants, stimulus ratings confirmed successful fear conditioning and participants showed a selective left-hemispheric enhancement of the P1 in response to LSF threat-faces. By contrast, CS differentiation in the SCR was not modulated by spatial frequencies but by stimulus duration, with longer CS presentations resulting in larger SCR to threat compared to neutral faces. For contingency unaware participants, trial-by-trial amplitudes of P1 and SCR were positively correlated. Data support the notion that magnocellular-cortical pathways adapt quickly to novel threat-associations and facilitate rapid threat retrieval even for perceptually neutral faces. However, at least in the short term, these signals do not necessarily associate with anticipatory arousal in SCR. ### Competing Interest Statement The authors have declared no competing interest.

Happy to share our newest preprint! I always wondered whether the (alleged) subcortical route of fear perception responds to newly acquired threat associations. Our research suggests that it does indeed, how cool!

A network of basolateral amygdala projection neurons contributes to stress-induced activation of the hypothalamic-pituitary-adrenal axis A network of basolateral amygdala neurons, but not singular projections, contributes to the neuroendocrine response to stress.

New lab paper drop, this one has been a long time coming! Driven by Rob Aukema (now a postdoc with Kerry Ressler) this paper in Science Advances answered the lingering question of what role the amygdala plays in stress-induced neuroendocrine responses.

Digital Eugenics and the Extinction of Humanity | TechPolicy.Press If we are to combat the AI industry’s push to build digital gods, we have to understand the ideology of the antihumanist project, writes Dr. Émile P. Torres.

There’s a reason Peter Thiel hesitated when asked in a recent interview if he “would prefer the human race to endure”:

Within certain tech circles, pro-extinctionism is a mainstream ideology—and some are trying to realize it.
