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.

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. 🧵

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!

is a strategy for observing multiple data streams in video and sound

e.g., watch an animal move while you listen to their physiological signals (or vice versa)
New preprint!

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.
mice use their eyes.
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! 👏
🧠 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.

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.

Theta oscillations in the medial temporal lobe support memory, but how they relate to eye and body movements during human navigation is unclear. This study shows that theta power increases during sacc...
