We illustrate that these top-down processes rely on left-lateralized sensorimotor networks und we ask what differentiates sensorimotor networks in the left from those in the right hemisphere
11/12

In this article, we review studies suggesting that predictive speech processing and dimension-selective attention enhance lateralization.
10/12

We believe that pronounced lateralization in speech processing arises because interpreting speech sounds engages a more complex, interconnected network than processing simple sounds—one that uses top-down mechanisms to actively shape input.

Interestingly, when training leads us to interpret an acoustic signal as speech—like in studies with sine wave speech—brain response patterns become more lateralized.

See for example Meyer et al. (2005):

In fact, Coull & Nobre (1998) showed that spatial attention activates a right-lateralized frontoparietal network, while temporal attention—possibly more relevant for speech—engages a left-lateralized network.

Still, it’s striking in neurorehabilitation clinics that left-hemisphere MCA strokes often lead to aphasia, while right-sided strokes lead to spatial hemineglect.

This made me wonder long ago whether there’s a link between attention functions and language processing in the left hemisphere.
6/12

McGettigan & Scott argued that lateralization relates more to linguistic processing, especially for speech(-like) stimuli.

Evidence for fast temporal lateralization is limited (see Oderbolz et al.)

Therefore, @davidpoeppel.bsky.social (2003) and Zatorre & Belin (2001) proposed that the hemispheres are differently specialized:

🧠 Right processes slow temporal & fine spectral cues,
🧠 Left handles faster temporal info.

The lateralization of speech and language is a hallmark of functional brain specialization.

However, thanks to imaging techniques, we now know that auditory speech processing occurs in both hemispheres.
