This pathway's existence is fundamental for understanding nonconscious emotional responses, but has been challenged as a result of a lack of evidence for short-latency fear-related responses in primate amygdala, including humans. We recorded human intracranial electrophysiological data and found fast amygdala responses, beginning 74-ms post-stimulus onset, to fearful, but not neutral or happy, facial expressions. These responses had considerably shorter latency than fear responses that we observed in visual cortex. Notably, fast amygdala responses were limited to low spatial frequency components of fearful faces, as predicted by magnocellular inputs to amygdala. Furthermore, fast amygdala responses were not evoked by photographs of arousing scenes, which is indicative of selective early reactivity to socially relevant visual information conveyed by fearful faces. These data therefore support the existence of a phylogenetically old subcortical pathway providing fast, but coarse, threat-related signals to human amygdala. https://sonar.ch/global/documents/232480 eng info:eu-repo/semantics/altIdentifier/doi/10.1038/nn.4324 info:eu-repo/semantics/altIdentifier/pmid/27294508 Nature neuroscience. - 2016 Adult Amygdala Brain Mapping Face Facial Expression Fear Female Happiness Humans Magnetic Resonance Imaging Male Reaction Time Task Performance and Analysis Visual Cortex A fast pathway for fear in human amygdala. http://purl.org/coar/resource_type/c_6501
