Individual neurons tune to complex speech sounds and cues
The Transmitter reports: Individual neurons in the cerebral cortex are finely tuned to the sounds of human speech—beyond just picking out consonants and vowels, two new independent studies show. The cells encode small sounds called phonemes that are said in a similar way; the order in which syllables are spoken; the beginning of sentences; vocal pitch; and word stress, among other features of speech. The studies were able to reveal this new level of detail by using Neuropixels probes, which…
