Temporal integration in human auditory cortex is predominantly yoked to absolute time www.nature.com/articles/s41... There's a difference between integrating across absolute time & structure (say) phonemes. Do cortical computations reflect time or structure? Results showed time-yoked computations ⏱️

Temporal integration in human auditory cortex is predominantly yoked to absolute time - Nature Neuroscience

Temporal integration throughout the human auditory cortex is predominantly locked to absolute time and does not vary with the duration of speech structures such as phonemes or words.

The work coming out of the Person lab is a must-read for me. www.biorxiv.org/content/10.1... This new paper shows that cerebellar output neurons encode both predictive and corrective movements, mechanistically linking feedforward and feedback control.

Ito et al (2025) A collicular map for touch-guided tongue control. Nature, 1-9. www.biorxiv.org/content/10.1... They observe that lick aiming by mice does not require activity in tongue sensory, premotor and motor cortices, but instead is dependent on a lateral region of the superior colliculus.

Inoue et al "A kinematically reasonable mechanism of tongue forward protrusion considering hyoid bone movements." www.sciencedirect.com/science/arti... Rightly points out that the role of the hyoid in speech is underinvestigated but the model and method used here is flawed and many questions remain.
