Our latest paper just came out in the Journal of Neuroscience “Neural Dynamics of the Processing of Speech Features: Evidence for a Progression of Features from Acoustic to Sentential Processing.” We follow the cortical processing of four different speech-like stimuli (dushk88.github.io/progression-) through the brain, using MEG, from early auditory cortex to areas processing semantic-level information. The results show that each language-sensitive processing stage shows both an early (bottom-up-like) cortical contribution and a late (top-down-like) cortical contribution consistent with predictive coding. jneurosci.org/content/45/11/e1

bioRxiv · Hierarchical encoding of natural sounds mixtures in ferret auditory cortexExtracting relevant auditory signals from complex natural scenes is a fundamental challenge for the auditory system. Sounds from multiple sources overlap in time and frequency. In particular, dynamic "foreground" sounds are often masked by more stationary "background" sounds. Human auditory cortex exhibits a hierarchical organization where background-invariant representations are progressively enhanced along the processing stream, from primary to non-primary regions. However, we do not know whether this organizational principle is conserved across species and which neural mechanisms drive this invariance. To address these questions, we investigated background invariance in ferret auditory cortex using functional ultrasound imaging (fUSI), which enables large-scale, high-resolution recordings of hemodynamic responses. We measured responses across primary, secondary, and tertiary auditory cortical regions as ferrets passively listened to mixtures of natural sounds and their components in isolation. We found a hierarchical gradient of background invariance, mirroring findings in humans: responses in primary auditory cortex reflected contributions from both foreground and background sounds, while background invariance increased in higher-order auditory regions. Using a spectrotemporal filter-bank model, we found that in ferrets, this hierarchical structure could be largely explained by tuning to low-order acoustic features. However, this model failed to fully account for background invariance in human non-primary auditory cortex, suggesting that additional, higher-order mechanisms are crucial for background segregation in humans. ### Competing Interest Statement The authors have declared no competing interest.

Duration adaptation depends on the perceived rather than physical duration and can be observed across sensory modalities journals.sagepub.com/doi/10.11 "duration adaptation relies on perceived duration and can occur across sensory modalities"; #crossmodal #multisensory #temporal #perception

"adapting to a subjectively matched #visual stimulus produced a significant aftereffect when the test stimulus was #auditory, indicating the existence of the cross-modal adaptation."

I do not do this often, share a list that is.

This is an adventurous list, it is eclectic, yet follows mainly electronic music, some words, but not constantly to my taste.
It a sensory bass heavy playlist. A couple of my tops of tops is on here. Still working on last bit.
Be kind to it, and it will earbang your fillings out with the correct gear.
Suggest skullcandy Crusher Wireless or equal.
Cheers to your ears.

New perspectives paper w/ Erick Gallun and KC Lee!
We discuss known inconsistencies in the dual-task listening effort literature and suggest to move forward, we must first look backward: better integrating models of resource capacity/allocation and task-switching from domains outside hearing research.
