We propose an alternative in which we compare neural responses to a natural stimulus and a “model-matched” synthetic stimulus designed to yield the same responses as the natural stimulus. One challenge with this approach is that different features are often correlated across natural stimuli, making their contributions hard to tease apart. A standard way to test sensory models is to predict responses to natural stimuli. Modeling neural responses to natural stimuli is a core goal of sensory neuroscience. Our methodology enables stronger tests of sensory models and could be broadly applied in other domains. Our results provide a signature of hierarchical organization in human auditory cortex, and suggest that nonprimary regions compute higher-order stimulus properties that are not well captured by traditional models. This dissociation between primary and nonprimary regions was less clear from model predictions due to the influence of feature correlations across natural stimuli. We observed that fMRI responses to natural and model-matched stimuli were nearly equivalent in primary auditory cortex (PAC) but that nonprimary regions, including those selective for music or speech, showed highly divergent responses to the two sound sets. Prior studies have that shown that this model has good predictive power throughout auditory cortex, but this finding could reflect feature correlations in natural stimuli. We used this approach to test whether a common model of auditory cortex-in which spectrogram-like peripheral input is processed by linear spectrotemporal filters-can explain fMRI responses in humans to natural sounds. Here, we propose a simple alternative for testing a sensory model: we synthesize a stimulus that yields the same model response as each of a set of natural stimuli, and test whether the natural and “model-matched” stimuli elicit the same neural responses. One challenge is that distinct model features are often correlated across natural stimuli, and thus model features can predict neural responses even if they do not in fact drive them. As a consequence, sensory models are often tested by comparing neural responses to natural stimuli with model responses to those stimuli. "This was from the Anjana hotel in Turkey," another user commented.A central goal of sensory neuroscience is to construct models that can explain neural responses to natural stimuli. □Este video viralizado, no corresponde a la Isla de Epstein.Įs el Hotel 5 estrellas - Titanic Mardin Palace, un hotel de Disney en turquia para niños con parques acuaticos. "It is the 5-star Hotel - Titanic Mardin Palace, a Disney hotel in Turkey for children with water parks," one X user claimed. For reference, Politifact reported in January 2023 that social media users believed "Kappy was murdered for exposing Hollywood pedophiles," and did not commit suicide as officials informed.įinally, various social media users suggested the video was not captured in a house on Epstein's island. "Video posted by actor and musician Isaac Kappy, who was found dead shortly after," a post in Portuguese shared on X in February 2023 captioned the viral video. Isaac "committed suicide by jumping off a bridge" #PIZZAGATE #PizzaGateIsReal /vwerTnllnj The video was recorded on Jeffrey Epstein's private Pedophile’s Island. Video shared by the actor Isaac Kappy before he was killed for reporting the Elite Human Trafficking and Child Abuse Network. Multiple social media users also linked the video to the QAnon and Pizzagate conspiracy theories, as well as Isaac Kappy, an American actor, musician, and conspiracy theorist. For instance, one post on Reddit linked the video with actor Tom Hanks with a caption, "Man Claims Tom Hanks is a Pedophile, releases video upon death." Moreover, we found instances of the video being shared in 2019 in a Facebook post and on an online 4chan forum. We used Google reverse-image search to investigate the origins of the video and found it was shared multiple times in 20. ![]() ![]() In short, we found no evidence the viral video revealed girls on Epstein's island. The unsealing of the documents caused a stir on social media, with various rumors appearing on the topic. Epstein died in jail at his own hands in 2019 while awaiting trial on charges of sex trafficking young girls. What is it they’re doing, and to what, and WHY!?Įpstein was back in the news in early 2024 after a judge ordered documents unsealed in a lawsuit filed against his associate/partner in crime, Ghislaine Maxwell.
