A study published in Nature Human Behavior reveals that general anesthesia suppresses unique functional connectivity patterns in the brain, making it difficult to distinguish individuals based on their neural activity. This effect is strongest in uniquely human brain regions and has implications for understanding and potentially aiding consciousness recovery.
A new study reveals that people with lower self-awareness about their own decision accuracy show stronger brain responses to morally charged political issues, potentially explaining why some political beliefs are so rigid.
This article details a DIY atomic force microscope built from mostly junk parts. It utilizes a laser-based deflection reading system instead of traditional piezo motors, achieving 35-um resolution with readily available materials. The project focuses on simplicity and cost-effectiveness, making it suitable for educational purposes.
Rejuvenating the brain’s lymphatic vessels can enhance memory in aging mice by improving the removal of waste products from the brain.
This study demonstrates that neural activity in the human brain aligns linearly with the internal contextual embeddings of speech and language within large language models (LLMs) as they process everyday conversations.
The article explores the concept of consciousness, arguing for a reductionist approach by Alan J. McComas. It discusses how consciousness is a function of the brain, with neural activities often preceding awareness. The piece also examines the role of large language models in chatbots, highlighting potential manipulative techniques and the need for vigilance in interactions. Additionally, it addresses the integration of AI in research and evolving journal standards.
Scientists are exploring the capabilities of the DeepSeek-R1 AI model, released by a Chinese firm. This open and cost-effective model performs comparably to industry leaders in solving mathematical and scientific problems. Researchers are leveraging its accessibility to create custom models for specific disciplines, although it still struggles with some tasks.
Researchers at the University of Chicago have discovered that the fine control octopuses have over their arms is due to the segmentation of their nervous system circuitry, which is distributed with a significant number of neurons in the arms. This unique system allows for independent decision-making in each arm and precise control, potentially informing future soft robot designs.
