How do our brains process speech? – Gareth Gaskell
The lesson explores how our brains process speech, highlighting that by age 20, individuals typically know tens of thousands of words, with recognition accuracy reaching 98%. It explains the brain’s parallel processing capabilities, where unique neuron patterns represent words, allowing for rapid identification and meaning extraction, especially when contextual cues are present. Additionally, it discusses how new words are initially stored separately in the hippocampus and gradually integrated into the existing vocabulary during sleep, ensuring our language skills evolve without interference.
Ethical dilemma: The burger murders – George Siedel and Christine Ladwig
