How do we prevent memories from competing to guide attention? More distinct hippocampal representations for competing memories are linked to precise preparatory coding in visual cortex & more accurate eye movements to target locations. Thrilled to share this work by the incomparable Serra Favila!

Hippocampal mechanisms underlying the resolution of competition in memory and perception - Nature Communications

Memory and perception both require selecting behaviorally relevant information. Here, the authors show that more distinct hippocampal memories are linked to precise anticipatory signals in visual cort...

On a quick skim, the core function that OSF will fulfil is registration of studies (plus protocols and analysis plans) and hosting preprints. This means we will need to find data repositories for new projects following mid-November; perhaps Github, Zenodo, or university-operated commons.

I am recruiting a postdoctoral researcher and a PhD student, funded by a new ERC grant. The grant focuses on the role of the hippocampus in visual perception, using 7T fMRI (hippocampal subfields, cortical layers) and MEG+iEEG. The intended start dates for both positions are in early 2027. 🧠🟦 1/3

Avec l’âge, la vue, la proprioception ou l’oreille interne deviennent moins efficaces. Mais que se passe-t-il dans le cerveau ? Une nouvelle étude montre que les personnes âgées mobilisent davantage de ressources mentales pour garder l’équilibre et réagir aux imprévus.

I’ve been leading a few discussions on #AgenticAI in research lately. Honestly, every department should organize a colloquium on this ASAP. It's evolving so fast, students are using it, and many don't understand risks like prompt injections. Many opportunities too. Put this on your agenda! 1/2

Our work on how neural circuits in the cerebellum encode prior probabilities led by Julius Koppen is out now in Nature Neuroscience www.nature.com/articles/s41... Big thanks to Julius Koppen & the whole team! And dedicated to all of us who found inspiration in Bayesian theories of the brain!

This study shows that cerebellar circuits learn and encode prior probabilities of event timing. Cell-type-specific neural activity reflects environmental statistics and guides predictive motor behavio...

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. plos.io/4dwJhR8 Huge congrats to Humza & team! 👏

Eye movements reflect memory-related theta activity in the human brain

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...

How do MTL theta oscillations relate to eye & body movements during navigation? @suthanalab.bsky.social &co show that #theta power increases during #saccades under memory demands, linking exploratory gaze & planning to memory‑related dynamics during #navigation @plosbiology.org 🧪 plos.io/4dwJhR8

Experimental design and task. Top left: Intracranial electroencephalographic activity, eye and body movements were recorded as participants freely walked around the room. Wall-mounted motion-tracking cameras recorded the position of on-body reflective markers. Participants also wore an eye-tracking headset to monitor saccadic eye movements. A snapshot from the eye-facing camera is shown in the bottom right. For illustrative purposes, an experimenter is shown wearing the full setup. Top right: MRI of an example participant with an implanted RNS System. Purple dots indicate the location of four electrode contacts in the left medial temporal lobe (MTL). The top left inset shows an X-ray used to localize electrode positions. Bottom left: The environment contained 20 visible wall-mounted signs and three invisible circular target locations (0.7 m diameter). At the start of the task, participants freely explored the room to locate the invisible targets; each time a target was reached, an auditory tone signaled success, allowing them to gradually learn and remember these locations through experience. The task then alternated between two conditions: “visually-cued” navigation, during which participants navigated to a wall-mounted sign (e.g., “Blue 3”), and “memory-cued” navigation, during which they recalled and navigated to the previously learned invisible targets (e.g., “T”).
