Thank you!
Thank you!
It's an interesting question and I don't know! I would hypothesize that they mature earlier though because babies can perceive prosody but not yet language
๐กIn sum, prosody ๐๐๐ฎ๐ป๐ฑ๐ ๐ผ๐๐ ๐ฎ๐บ๐ผ๐ป๐ด ๐ป๐ผ๐ป-๐๐ฒ๐ฟ๐ฏ๐ฎ๐น ๐๐ถ๐ด๐ป๐ฎ๐น๐: face/body/hand/voice gestures separate from language areas (Deen 2015; Pritchett 2018; Jouravlev 2019), but prosody engages themโlikely because it always co-occurs with speech and shares much information with verbal content. 14/
๐ Together, these profiles show that prosody processing occupies a ๐ฑ๐ถ๐๐๐ถ๐ป๐ฐ๐ ๐ณ๐๐ป๐ฐ๐๐ถ๐ผ๐ป๐ฎ๐น ๐ป๐ถ๐ฐ๐ต๐ฒ in the human brain, while maintaining tight links with verbal language processing and the processing of dynamic facial cues. 13/
๐๐ฅ๐ฒ๐๐๐น๐ ๐ฑ:
Prosody areas are separable but partly overlapping with ๐ฑ๐๐ป๐ฎ๐บ๐ถ๐ฐ ๐ณ๐ฎ๐ฐ๐ฒ perception areas. This overlap may reflect the need to integrate prosody with other non-verbal communication signals. 12/
๐ฃ๏ธ Interestingly, the dominant LH lang areas are mainly sensitive to prosody when verbal content is absent. For sentences, responses are already high without prosody, but for nonwords, prosody plausibly helps extract some information (perhaps related to sentence structure). 11/

Prosody areas are distinct from ๐บ๐๐น๐๐ถ๐ฝ๐น๐ฒ-๐ฑ๐ฒ๐บ๐ฎ๐ป๐ฑ (๐ ๐) cognitive regions in both response profiles and fine-grained voxel activation patterns. Thus, prosody responses are not driven by effort or general attention. 8/

Prosody areas are distinct from ๐ฝ๐ถ๐๐ฐ๐ต and ๐๐ฝ๐ฒ๐ฒ๐ฐ๐ต perception areas, differing in both response profiles and fine-grained voxel activation patterns measured using spatial correlations. Thus, prosody sensitivity cannot be explained by basic auditory responses. 7/
๐ ๐ฅ๐ฒ๐๐๐น๐ ๐ญ: A bilateral set of temporal+frontal areas responded robustly to prosody in both sentences and nonwords. Interestingly, these areas were also modulated by verbal content (sentences>nonwords). The temporal areas showed generalization to other, natural stimuli. 6/

To remove sentence-level prosody (pitch+timing), we compared naturally produced expressive sentences with versions of the same sentences where each word was recorded separately and spliced. Matched nonword stimuli used the same manipulation. 5/

Are there areas specialized for prosody, or is prosodic information handled by other systemsโauditory pitch/speech areas, cognitive control areas, the language network (Fedorenko et al. 2024), or social perception areas? 2/

The pattern of pitch, loudness, and tempo that overlays speech. Prosody can signal whether an utterance is a statement or a question, highlight important words, and covey affect. It is crucial for communication and language learning. 1/

Inline citations with only first author name, or first two co-first author names.
If you're finishing your camera-ready for ACL or ICML and want to cite co-first authors more fairly, I just made a simple fix to do this! Just add $^*$ to the authors' names in your bibtex, and the citations should change :)
