Excited to share our review, w. @ShanyGrossman (shared 1st!) and @nico_schuck where we discuss representational spaces in OFC/vmPFC and in deep RL models, featuring values, states and much more! cell.com/trends/neuroscience…. Fresh from the (virtual) print now in @TrendsNeuro , 1/4

Representational spaces in orbitofrontal and ventromedial prefrontal cortex: task states, values,...

The orbitofrontal cortex (OFC) and ventromedial-prefrontal cortex (vmPFC) play a key role in decision-making and encode task states in addition to expected value. We review evidence suggesting a...

Our preprint is online!  We show how the hippocampal-entorhinal cognitive maps could solve the general problem of representing and relating multiple alternative action plans.  Work together with @vigano_s @reznikdan @PatrickHaggard @doellerlab biorxiv.org/content/10.1101/…

Hippocampal-entorhinal cognitive maps and cortical motor system represent action plans and their...

Efficiently interacting with the environment requires weighing and selecting among multiple alternative actions based on their associated outcomes. However, the neural mechanisms underlying these...

Our new preprint is live: We show that the anterior hippocampus integrates episodic and spatial context signals - work together with @Naomis_brain @mona_garvert @doellerlab biorxiv.org/content/10.1101/…

Integrating episodic and spatial context signals in the hippocampus

Episodic and spatial memory are the two key components of the mnemonic system in humans. Episodic memory enables us to remember events from the past whereas spatial memory enables us to form a...

One of my PhD projects is online! We show that category prototypes correspond to interpolated states in a cognitive map that guide cortical pattern completion during category-based decisions. w/ Mirko Thalmann, @cpilab, @doellerlab, @ThevesStephanie biorxiv.org/content/10.1101/…

The hippocampus supports interpolation into new states during category abstraction

The hippocampus forms concepts by integrating multi-feature relations into a unified representation. A common yet unconfirmed assumption is that such cognitive maps afford interpolations to never-e...

Wie gelingt es unserem #Gehirn, in Entscheidungssituationen gute Vorhersagen zu treffen und die beste Option für die #Zukunft zu wählen? @NitschAlex & Christian Doeller @doellerlab sind gemeinsam mit @nico_schuck dieser Frage in @NatureComms nachgegangen: tinyurl.com/yzyyz5sf

Our new preprint is live: We show that the entorhinal cortex uses a grid-like representation to encode an abstract value space during prospective decision making - work together with @mona_garvert @jacobbellmund @nico_schuck @doellerlab biorxiv.org/content/10.1101/…

Grid-like entorhinal representation of an abstract value space during prospective decision making

Everyday decisions require us to predict how valuable different choice options will be in the future. Prior studies have identified a cognitive map in the hippocampal-entorhinal system that encodes...

There has been a lot of progress in our understanding of how the brain organises relationships in cognitive maps. But how is this knowledge used when guiding novel choice? Work with @TankredSaanum, @cpilab, @nico_schuck & @doellerlab now in @NatureNeuro rdcu.be/c83tL

Excited about our new preprint! biorxiv.org/content/10.1101/… Here, we investigate how multiple hippocampal cognitive maps are used for generalization, and the role the orbitofrontal cortex plays in updating hippocampal world models competing for behavioral control.

Hippocampal spatio-temporal cognitive maps adaptively guide reward generalization

The brain forms cognitive maps of relational knowledge, an organizing principle thought to underlie our ability to generalize and make inferences. However, how can a relevant map be selected in...
