Here’s an interesting “last mile” thing that’s often over-looked. When you park your bike at the bike parking station in downtown Eindhoven, you can pick up a free baby stroller for walking around with your child!
Neural representation of human experimenters in the bat hippocampus - Nature Neuroscience

Snyder et al. report that hippocampal neurons in Egyptian fruit bats modulate their activity depending on the position and identity of human experimenters when bats are flying and encode experimenter position and identity when bats are stationary.

If you're at #FENS2024 come say hi tomorrow morning! (PS01-26AM-003)

We can chat about population drift in the entorhinal cortices and hippocampus during free exploration and sensory minimized conditions 😊🌻🐀

Remember to drop by my poster tomorrow morning! While you're there check out the 8 awesome posters surrounding me from the #Moser group.

How are events segmented and organized in time? And how might this impact our perception and memory? Check out our work here on how neural trajectories in the lateral entorhinal cortex inherently drift over time, but abruptly shift at event boundaries to discretize a continuous experience. https://www.biorxiv.org/content/10.1101/2024.06.17.599402v1 https://x.com/EdvardMoser/status/1802967173196808557 #Events #Time #Timing #Memory #Dynamics #Experience #Circuits #EntorhinalCortex #Hippocampus #AnimalBehavior #Preprint

Fact gem of the day (#2): the ecstatic auras of Fyodor Dostoevsky

You probably know that Dostoevsky wrote Crime and Punishment, as well as the Brothers Karamazov. Did you also know that he had a unique form of epilepsy? In his case, the ramp up to a seizure was "a happiness unthinkable in the normal state and unimaginable for anyone who hasn’t experienced it."

It's called an "ecstatic aura."

Epilepsy and Ecstatic Experiences: The Role of the Insula

Ecstatic epilepsy is a rare form of focal epilepsy in which the aura (beginning of the seizures) consists of a blissful state of mental clarity/feeling of certainty. Such a state has also been described as a “religious” or mystical experience. ...

https://www.biorxiv.org/content/10.1101/2024.06.17.599402v1 Interesting preprint from the Moserlab at #NTNU on how multiple timescales are multiplexed in the lateral entorhinal cortex of mice engaged in foraging. The authors explore timescales up to minutes and show that these timescales are encoded primarily through the slow drift in firing rates of individual neurons. Events are encoded as discrete changes in the population trajectories. #neuroscience #hippocampus
Oh and I'll be at #FENS2024 in #Vienna next week. Poster on Wednesday: PS01-26AM-005. Stop by to discuss more in person!
