Universal scale-free representations in human visual cortex
Author summary The human cerebral cortex is thought to encode sensory information in population activity patterns, but the statistical structure of these population codes has yet to be characterized. By examining large-scale neuroimaging recordings of human vision using a spectral approach more common in physics than neuroscience, we reveal the universal scale-free structure of population codes in visual cortex, which is found in all subjects and at multiple stages of visual processing.

2023–2024 El Niño triggered record-breaking sea level spike along African coastlines, study finds
Africa's coastlines are under growing threat as sea levels climb faster than ever, driven by decades of global warming caused by human activity, natural climate cycles, and warming ocean waters. Between 2009 and 2024, the continent experienced a 73% increase in sea-level rise, according to a recent study published in Communications Earth & Environment.

'Mind-captioning' technique can read human thoughts from brain scans
Reading brain activity with advanced technologies is not a new concept. However, most techniques have focused on identifying single words associated with an object or action a person is seeing or thinking of, or matching up brain signals that correspond to spoken words. Some methods used caption databases or deep neural networks, but these approaches were limited by database word coverage or introduced information not present in the brain. Generating detailed, structured descriptions of complex…

AI is everywhere. In general, as many other (medical) illustrators I am sure, I have feared it will one day take our jobs. Yesterday, my friend Stephanie E. sent me the image on the right. A surgeon with a large Instagram following (Alexandre Mensier) posted it to teach people about Twin-to-Twin Transfusion Syndrome.

What is sensory substitution? When I speak to you and say, "Imagine a rising bright line", and you "see" a rising bright line in your mind's eye, that's mental imagery guided by sound, a form of sensory substitution.

Effects of eye closure on the spiking activity of human lateral geniculate neurons #LGN

Effects of eye closure on the spiking activity of human lateral geniculate neurons - Nature Communications
The LGN is a critical stage between the retina and visual cortex, but the properties of human LGN neurons are not fully understood. Here the authors report that they closely resemble those in monkeys and that closure of one eye increases the activity of putative inhibitory neurons connected to that eye.

LaVCa: LLM-assisted Visual Cortex Captioning
Understanding the property of neural populations (or voxels) in the human brain can advance our comprehension of human perceptual and cognitive processing capabilities and contribute to developing brain-inspired computer models. Recent encoding models using deep neural networks (DNNs) have successfully predicted voxel-wise activity. However, interpreting the properties that explain voxel responses remains challenging because of the black-box nature of DNNs. As a solution, we propose LLM-assiste…

Who are we writing for in the age of AI? Good writers write with readers in mind, and most assume those readers are human. As much as we might hope this is the case, however, the reality of the Internet age is that the first readers of our texts are machines. This didn’t start with large language models. Back in 2009, Facebook replaced its chronological feed with an algorithmic one, and now “For You” screens are the default in most social media platforms. Documentaries like The Social D…
