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.
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.
A unique resource for hippocampus researchers and learners, offering tools to build and explore models of the hippocampus and its components using powerful modeling workflows.
A comprehensive guide to brain maps compiled by a space shuttle guidance system engineer, detailing the brain's advanced circuitry and its comparisons to sophisticated technology.
The article discusses various regions of the brain, highlighting their functional roles in vision, balance, navigation, and computational processing.
The default mode network (DMN) plays a critical role in human creativity and the generation of ideas, according to recent studies. Researchers are exploring how manipulating this network can influence creativity.
A study reveals that the brain stores memories in three parallel copies using different sets of neurons. This could have implications for treating traumatic memories.
