Summary: Modern computing methods like text mining, face detection, and melodic extraction are allowing cognitive scientists to analyze historical cultural artifacts at scale, uncovering psychological data of past societies. By studying media consumption, such as the prevalence of sad music or the portrayal of leaders in portraits, researchers can infer societal psychological trends. The review …
Summary: Researchers used the simple worm, Caenorhabditis elegans, to gain profound insights into how neural information flows in the brain. Using advanced techniques like optogenetics, they visually tracked signal flow in real-time, neuron by neuron, to chart its pathways. Contrary to predictions from the worm’s connectome map, they found critical “wireless signals” involving molecular releases …
Summary: New research delves into how adults make sense of the limited vocabulary of young children. Through analyzing thousands of hours of transcribed audio, researchers created computational models to understand adult interpretations of baby talk. The most successful models relied on context from previous conversations and knowledge of common mispronunciation. This context-based interpretation by adults …
Analysis of Martian seismic data recorded by the InSight mission in combination with first-principles simulations of the seismic properties of liquid metal alloys have revealed that Mars’s liquid iron core is surrounded by a 150-km thick molten silicate layer, as a consequence of which its core is smaller than previously proposed. The decrease in core …
Summary: Researchers have discovered differences in functional brain connectivity in individuals with and without schizophrenia, shedding light on the neural basis of the disorder. The brain’s cortex regulates sensory information, and its disorganization can lead to symptoms like loss of executive control in schizophrenia. Through advanced brain imaging and mathematical techniques, the study revealed impairment …
Summary: A new study delves into the enigmatic realm of deep neural networks, discovering that while these models can identify objects akin to human sensory systems, their recognition strategies diverge from human perception. When prompted to generate stimuli similar to a given input, the networks often produced unrecognizable or distorted images and sounds. This indicates …
Researchers from the University of California San Diego, in a major collaborative effort, have mapped gene switches in different brain cell types by analyzing over a million human brain cells. This study, part of the BRAIN Initiative, highlighted the relationship between certain cell types and neuropsychiatric disorders. They further used AI to forecast the effects …
