This article explores the connection between strategic thinking in games like chess, the behaviors of manipulators (like drug dealers), and the neurological basis of 'theory of mind' – our ability to understand others' perspectives. A recent study suggests a link between forward-thinking and manipulation, with brain activity during negotiation mirroring that seen in chess players.
A new study suggests the thalamus plays a key role in regulating conscious perception, acting as a gateway between sensory signals and the cerebral cortex. Researchers used data from patients with pre-existing electrodes to observe brain activity during visual perception tasks.
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.
Researchers have found evidence suggesting that intelligence evolved independently in birds and mammals, rather than being inherited from a common ancestor. This indicates that complex neural circuits supporting cognition arose multiple times in vertebrates.
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.
Researchers found that meditation led to changes in activity in the amygdala and hippocampus, key brain regions involved in emotional regulation and memory. The study may help explain the positive impact of meditation on memory and emotional regulation.
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.
New research shows that glyphosate, a widely used herbicide, can cause lasting brain inflammation and accelerate Alzheimer's-like pathology in mice, raising concerns about its safety for humans.
Researchers from ISTA and Max Planck Institute have uncovered new details about molecular mechanisms driving memory processing at mossy fiber synapses in the hippocampus, crucial for memory formation.
The hippocampus is known to convert short-term memory into long-term memory. The study sheds light on how structural and functional changes in mossy fiber synapses may facilitate the encoding and storage of memories in the hippocampus.
The new research focuses on the mossy fiber synapse, a key connection point between neurons in the hippocampus. The scientists used a novel technique called "Flash and Freeze" combined with freeze fracture labeling to study the dynamic changes in proteins Cav2.1 calcium channels and Munc13 during signal processing. They found that upon stimulation, these proteins rearranged and moved closer together, enhancing neurotransmitter release and potentially contributing to memory formation.
