(7/n) Great work from Sara Carta, in close collaboration with co-supervisors Alejandro Lopez Valdes, Emina Alickovic, Johannes Zaar. Thanks to Demant Fonden, Eriksholm Research Centre, @researchireland.ie for your support!

(6/n) Here we also looked into envelope tracking vs. lexical processing, and investigated how lexical context is updated during an attention switch.

(5/n) Indeed, there are lots of considerations that we discuss. For instance, the cortical tracking doesn't go to zero after a switch, as unattended streams are processed to an extent. (e.g., elifesciences.org/reviewed-pre...).

(4/n) This phenomenon might be key to our ability to explore other conversations (before switching) while listening to a given speaker

(3/n) We found a clear asymmetry in this transition, with the engagement starting much earlier than the engagement. This leads to a brief moment where both speakers are encoded in the human cortex.

(2/n) The intuition is quite simple. When switching from a speaker A to a speaker B, the cortical tracking of A and B should decrease (disengagement) and increase (engagement) respectively. That's one key principle that BCIs for auditory attention decoding have been using

inspired by all the brilliant work from auditory visual processing and groups from @cnspworkshop.bsky.social
