Poster X8 on Tuesday morning, 8-12

#SfN25 's hottest club is Poster X8 Tuesday Morning. This club has everything: mice hunting robotic bait, quantitative behavior modeling, chronic superior colliculus Neuropixel data, and GLM encoding/decoding, not to mention the cheap new DAQ EVERYONE's been rumbling about. See you there!

Parsing social context in auditory forebrain of male zebra finches To understand the influence of natural behavioral context on neural activity requires studying awake-behaving animals. Microdrive devices facilitate bridging behavior and physiology to examine neural ...

8/ Want a deeper dive? Check out the full paper at journals.plos.org/plosone/arti.... Happy to chat more about social neural coding or how to implement similar recording gear!

7/ Tools: Our open-access microdrive designβ€”orchestrating reliable, long-term neural recordingsβ€”is freely shared (CaltechDATA repository) for the community to use and build upon.

6/ Takeaway: NCM isn’t sensitive to whether it’s the bird singing or hearing itselfβ€”but it is sensitive to the presence of other birds. Suggests a specialized auditory representation tuned to social environment.

5/ Key insights:
β€’ Behavioral context (self- vs. external song) β†’ no change in neural encoding
β€’ Social context (alone vs. with conspecifics) β†’ marked modulation in response strength & selectivity
Plus, we observed stimulus-specific local field potential correlates in NCM.

4/ Our microdrive system is lightweight, durable for months, and broadly accessibleβ€”overcoming major hurdles in chronic recordings in small animals.

3/ We compared two contexts:
β€’ Behavioral – hearing own song vs. actively singing it
β€’ Social – listening while alone vs. in the presence of others
We found that NCM responses remained consistent across behavioral contexts but were changed social listening situations.

2/ Why zebra finches? They’re highly vocal and socialβ€”perfect for studying how neural responses in the auditory cortex (aka caudomedial nidopallium, or NCM) change with behavioral and social context.

1/ Late to the game to publicize my paper with @healeylab.bsky.social ocial: Parsing social context in auditory forebrain of male zebra finches (PLOS ONE, March 19, 2025). We also developed a low-cost microdrive for long-term neural recording in freely behaving finches.

Wow! Thank you @animal-prattle.bsky.social and @timsainburg.bsky.social for reading this paper and skeeting it up! I haven't even skeeted it myself yet.
