A biomimetic model of the corticostriatal loop discovered neurons that predict errors before they happen. About 20% of the neural population are 'incongruent' — their activity doesn't match the dominant decision signal. When researchers checked real anim...

Lab-grown brain circuits reveal who's really in charge. Nagoya University researchers fused thalamic and cortical organoids derived from human iPS cells, watching axons extend bidirectionally to form synapses. Neural activity propagates from thalamus to co...
