Study points to whole-brain network coordination as a key feature of general intelligence

3. März 2026 Von KI berichtet Bild generiert von KI Fakten geprüft

University of Notre Dame researchers report evidence that general intelligence is associated with how efficiently and flexibly brain networks coordinate across the whole connectome, rather than being localized to a single “smart” region. The findings, published in Nature Communications, are based on neuroimaging and cognitive data from 831 Human Connectome Project participants and an additional 145 adults from the INSIGHT Study.

Study finds phone notifications disrupt attention for 7 seconds

Smartphone notifications interrupt users' concentration for about seven seconds, according to new research from the University of Lausanne. The effect is stronger for personally relevant alerts, with frequent checks amplifying the distraction. Researchers warn that these brief interruptions accumulate over hundreds of daily pings.

Research indicates brain development continues into the 30s

A common belief that the frontal lobe fully develops by age 25 has been challenged by recent neuroscience findings. New brain-imaging studies reveal that key neural wiring and network efficiency evolve well into the early 30s. This extended timeline highlights ongoing maturation processes in the brain.

Northwestern scientists nudge dreams to boost puzzle-solving

15. Februar 2026 Von KI berichtet

Neuroscientists at Northwestern University have demonstrated that subtle sound cues during REM sleep can influence dream content, leading to improved creativity in solving brain teasers. In a study with 20 participants, 75% reported dreams related to cued puzzles, which they solved at higher rates the next day. The findings suggest sleep may play a key role in creative problem-solving.

Laut mit sich selbst sprechen ist normal, sagt die Psychologie

Laut mit sich selbst zu sprechen ist eine gängige Gewohnheit, die viele Menschen zu Hause oder beim Gehen praktizieren, und die Psychologie betrachtet es als externe Äußerung des inneren Dialogs. Dieses Phänomen hilft, Ideen zu ordnen, Entscheidungen zu treffen und Emotionen zu regulieren, ohne ein Zeichen geistiger Unausgeglichenheit zu sein. Es gibt nur Anlass zur Sorge, wenn es den Alltag stört oder mit anderen Symptomen einhergeht.

Study uncovers overlap in brain networks for episodic and semantic memory

3. Februar 2026 Von KI berichtet

A new brain imaging study has found that recalling facts and personal experiences activates nearly identical neural networks, challenging long-held views on memory systems. Researchers from the University of Nottingham and University of Cambridge used fMRI scans on 40 participants to compare these memory types. The results, published in Nature Human Behaviour, suggest a rethink in how memory is studied and could inform treatments for Alzheimer's and dementia.
