1/8 New preprint alert!
How are signals from the heart encoded in the brain?
What could be the functional implications of cardioception?
We found that neurons in the posterior insular cortex are precisely tuned to heartbeats, and that this cardio-insular coupling supports emotion coding in mice.
New preprint!
Follow the thread to find out about the exciting work of an outstanding postdoc in my lab @merylneuro.bsky.social !!!
Losing one side of Superior Colliculus is bad, but losing both sides seems fine. Wait, what?
Flora & team discovered why: both sides press for contra actions and against inaction, obeying an incredibly simple additive rule.
Out today in bioRxiv:

1/8. New preprint! ✨
How spontaneous is spontaneous behavior? 🧠🐭
We found that whole-brain fUSi signals predicted spontaneous behavioral transitions seconds in advance. Inhibiting one node of this transition-prone state, the medial septum, facilitated switching!

1/8. New preprint!
Using fUSi in head-fixed mice🐭, we found that arousal events trigger a brain-wide wave of activity 🌊🧠.
Surprisingly, this pattern was preserved during opto manipulations of the locus coeruleus, pointing to a minor role for noradrenergic tone.

Visualizing and Sonifying NeuroData (ViSoND)
github.com/Smear-Lab/Vi...
is a strategy for observing multiple data streams in video and sound
www.biorxiv.org/content/10.6...
e.g., watch an animal move while you listen to their physiological signals (or vice versa)
🧠 On April 14th, we will welcome Dr. Rebecca Jordan from the The University of Edinburgh! She will share her research on how the #brain learns to #predict sensory input and integrate #sensorimotor information.

New lab paper! 🧠
Human hippocampal & MTL theta activity is linked to eye movements, but only during memory-guided navigation. Theta is also strongest during longer, more exploratory eye movements.

Huge congrats to Humza & team! 👏
How do the basal ganglia turn what you see into what you do?
New preprint w/ @kenneth-harris.bsky.social, @flickerfusion.bsky.social & @carandinilab.net: we recorded across striatum, GPe & SNr in a Go/NoGo task. Striatum encodes which stimulus, GPe & SNr encode action. 🧵
