## Executive GIST (TL;DR)
- Investigators reported discovery of two discrete **voice patches** in the auditory cortex of the common **marmoset**, detected with multimodal optical imaging approaches. - The study team used both intrinsic signal imaging and **calcium imaging** to measure activity directly from the smooth cortical surface in a noise-controlled environment. - Data indicated two anatomically localized patches, described as posterior and anterior, situated relative to the tonotopic map and core/noncore auditory areas. - Both patches preferentially responded to marmoset vocalizations rather than to generic spectral features; responses encoded both call type and caller identity. - Neural selectivity exceeded what would be expected from simple spectral tuning, according to the authors’ analyses. - Response properties differed between the posterior and anterior patches, with latency differences consistent with a hierarchical processing relationship. - Authors noted these findings align with voice/vocalization-selective regions reported on the lateral temporal cortex of humans and other primates, implying an evolutionarily conserved cortical organization supporting vocal communication. - The paper anchored functional localization to existing tonotopic and core/noncore maps; the source did not report detailed sample sizes, stimulus sets, exact imaging parameters, or statistical values in the abstract. - The study provides precise cortical localization but leaves specific methodological and quantitative details to the full article for verification.

In both humans and nonhuman primates, voice/vocalization-selective regions have been identified on the lateral temporal cortex. Here, we provide evidence of localized and hierarchically organized voice patches in the auditory cortex of the common marmoset, a highly vocal New World primate, using multimodal optical imaging techniques that directly measure activity from the smooth cortical surface in a noise-controlled environment. Both intrinsic imaging and calcium imaging data revealed two discrete voice patches in a region of the auditory cortex. Our results provided precise functional localization of the two voice patches (posterior and anterior) by anchoring their positions to the tonotopic map and core/noncore areas of the auditory cortex. Both patches preferentially respond to marmoset vocalizations, exhibit quantifiable neural selectivity beyond spectral features, and encode call type and caller identity. Distinct response properties reveal functional differentiation between the posterior and anterior voice patches, with latency differences consistent with a hierarchical relationship. These findings provide new evidence for an evolutionarily conserved cortical architecture in primates that supports vocal communication via voice patches, analogous to face processing systems in human and nonhuman primate brains.
