Hippocampus Rewires Memories to Predict Future Rewards

A preclinical study shows the hippocampus actively reorganizes memories to forecast rewards, with hippocampal neurons shifting their activity from the moment of reward to earlier task features as mice learn. Using long-term calcium imaging, researchers tracked cells over weeks, revealing a predictive, backward-shifting signal that refines the brain’s internal model of outcomes and offering a new lens on learning—and why decision-making falters early in Alzheimer's disease.

"Brain Waves Shape Our Perception of Speech"

A study by the Max Planck Institute reveals that brain wave timing influences how we perceive speech, with more probable sounds and words being recognized during less excitable brain wave phases. This finding supports the role of neural timing in language comprehension and has significant implications for predictive coding theories in speech perception.

"Interconnected Senses: The Influence of Predictive Coding on Our Sense of Smell"

A study from Stockholm University suggests that our sense of smell relies more on predictive coding than vision, challenging the notion of smell as a primitive sense. Through behavioral studies and fMRI brain imaging, the research demonstrates that smell is sophisticated and proactive, reacting to unexpected stimuli by engaging olfactory and visual brain regions. This unique sensory processing strategy underscores the importance of predictions and cues from other senses in accurately identifying odors, highlighting the advanced capabilities of the human sense of smell.
