- Sparse-to-dense coding transformation between hippocampal areas CA3 and CA1
A study published in Nature reveals that the hippocampus undergoes a CA3-to-CA1 coding transformation, which integrates rapid learning with an efficient, compressed neural code. This transformation is crucial for balancing memory flexibility and storage efficiency in the brain.
- Author Correction: Predictive coding of reward in the hippocampus
The article announces a correction to the author list of a research paper on predictive coding of reward in the hippocampus, published in Nature on May 12, 2026. The correction implies changes to the original authorship. The paper's topic is related to neuroscience and brain function.
- Plasticity and language in the anaesthetized human hippocampus
The hippocampus processes complex sensory stimuli even when a person is unconscious. This discovery was published in Nature on May 6, 2026. The study sheds light on the brain's ability to handle information in an anaesthetized state.
- The lights are out but someone’s home: sensory processing in anaesthetized human brains
Researchers made detailed neural recordings from the hippocampus in anaesthetized human brains, finding that neuronal activity responded to unusual auditory tones and could predict upcoming words in a phrase. The study sheds light on sensory processing in unconscious humans. The findings were published in Nature.
- Scientists found the brain doesn’t start blank, it starts full
The brain's memory center, the hippocampus, starts life with dense, random neural networks that become organized through pruning. This process creates a more efficient system for linking experiences and forming memories, challenging the 'blank-slate' brain theory.
