Beyond excited that this work from my DPhil is out now in @Nature. There's a music box in PFC! It's been a real privilege to work with such a talented team, especially @GabyMohamady who will be a formidable force in neuroscience for years to come.
“Where was I again?” Our study published today https://t.co/SssPQUDv7l reveals brain cells can form a coordinate system for our behaviours. Instead of locating where we are in the world, this coordinate system tells us “where we are” in a sequence of behaviours: 🧵below:

Can we use what we’ve learned about cognitive maps to understand social cognition, including theory of mind? If you’re interested in answering this question then this is a fantastic postdoc opportunity with @mkwittmann in collaboration with Chris summerfield and my lab.
📢 Job announcement: Two (!) 3-year postdoc jobs in our lab at UCL 📢 🧠💫🔊 Modelling, fMRI and non-invasive ultrasound, a new deep-brain stimulation method. https://t.co/Xh994dr48l Please RT

Incredible opportunities to work with @GabyMohamady in figuring out how PFC and hippocampus map the world and our behaviour, how these systems fail in psychosis, and how to rescue them. Those not interested in working with a generous mentor in a beautiful city need not apply 🧠
How do cognitive maps fail? And how can this help us understand/treat psychosis? My lab at Experimental Psychology, Oxford is hiring a Postdoc https://t.co/vuNh1nw31s and RA https://t.co/JtTv7lIKkk to answer these questions in mouse models. Here's why you might want to join: 🧵

Opportunities coming up to work with some incredible people on incredible neuroscience. Massive congratulations @GabyMohamady - nobody deserves it more!
Delighted to share that I’ll be joining @OxExpPsy as a group leader/Faculty next spring. My group will investigate how our cells build models of the world and of our internal goals, and how this goes wrong in disorders like schizophrenia.

I'm happy to share our Review article in @TrendsCognSci , "Cognitive Maps and Schizophrenia", synthesising evidence for representation-level abnormalities in the condition, and proposing directions for future work. https://t.co/5wUwAbFCTs

We think there's a music box in frontal cortex that can be programmed to play out behavioural sequences that share an abstract structure. Check out our new preprint, led by the formidable @GabyMohamady!
We’ve all heard of place cells: neurons that form a “cognitive map” representing the structure of the outside world. But what about our own structured behaviours? We took a deep mechanistic dive, out now on @biorxivpreprint : https://t.co/aguPskE1vm 🧵below:

2 month late tweeprint. Tldr: Theory unifying the algorithm and representation of hippocampal episodic memory and prefrontal working memory. Explains the representations artificial neural networks learn on sequence memory tasks, along with several prefrontal recordings. (1/N)

We have an RA/tech post in Oxford for rodent neuro. Thomas Akam is also advertising for an RA to work on related projects. Mice making flexible decisions. Hippocampal/frontal recordings/manips. Would could be cooler? https://t.co/0jzwU9QqfF

Are you interested in abstraction? cognitive maps? PFC? preplay? Or simply bored and want to come watch videos of mice doing clever inferences? We’ve got you covered! ... II-103, Poster session2, Friday 18/03, 8pm #cosyne2022

Really excited about this work from my DPhil being submitted to Cosyne 🎉 abstract task structure representations, remapping, zero-shot inferences, and task-space replay in some pretty clever mice
.@GabyMohamady, @AdamLoydHarris, @jcrwhittington, Mark Walton, Thomas Akam: Show that mouse mPFC neurons build generalisable state-space for sequential tasks. https://t.co/BhCRobhiiH

A preprint of our review: “The Shallow Cognitive Map Hypothesis: A Hippocampal framework for Thought Disorder in Schizophrenia.” is now available on PsyArXiv: https://t.co/C3tbdm0eb5 with the brilliant Ayesha Musa, Safia Khan and Minahil Mujahid. (1/4)

@andrea_e_martin & I present: On logical inference over brains, behaviour, and artificial neural networks! https://t.co/K8RAw50maM Formal logic allows us to describe metatheories in use in cognitive computational neuroscience, and helps us spot formal/inferential fallacies! 1/4

Dopamine lovers! Excited to share our preprint showing that dopamine reports belief updates, but has a limited causal influence on policy update during inference-guided behaviour 📜
biorxiv.org
Dopamine is thought to carry reward prediction errors (RPEs), which update values and hence modify future behaviour. However, updating values is not always the most efficient way of adapting to...
Dopamine reports reward prediction errors, but does not update policy, during inference-guided choice https://t.co/6UzS1D5PQr

if it's not a right angle its a wrong angle
It's a nice paper (doi:10.1038/s41592-019-0625-2), but the beam path schematic irks me. On the plus side, it prompted me to ponder whether I'm overly perfectionistic sometimes
