The belief that artificial consciousness is coming crucially depends on the assumption that consciousness is a computation.

In this new paper, we'll try to convince you that consciousness cannot be a computation

Communication of perceptual predictions from the hippocampus to the deep layers of the parahippocampal cortex High-resolution neuroimaging reveals stimulus-specific predictions sent from hippocampus to the neocortex during perception.

Our study using layer fMRI to study the direction of communication between the hippocampus and cortex during perceptual predictions is finally out in Science Advances! Predicted-but-omitted shapes are represented in CA2/3 and correlate specifically with deep layers of PHC, suggesting feedback. 🧠🟦

Compositional pretraining improves computational efficiency and matches animal behaviour on complex tasks - Nature Machine Intelligence Hocker et al. demonstrate a method for training recurrent neural networks, which they call ‘kindergarten curriculum learning’, involving pretraining on simple cognitive tasks to improve learning effic...

Constructing future behavior in the hippocampal formation through composition and replay - Nature Neuroscience A model of compositional state spaces in the hippocampus shows latent learning and rapid generalization. Bakermans et al. show that this model predicts the emergence of place responses in replay.

Happy to share the latest version of our work on compositional maps in hippocampus with Jo Warren, @jcrwhittington.bsky.social, @behrenstimb.bsky.social. We propose hippocampus constructs maps from cortical building blocks in replay – now with empirical support! www.nature.com/articles/s41... 1/9

Reasoning Goals and Representational Decisions in Computational Cognitive Neuroscience: Lessons From the Drift Diffusion Model The appropriate form of the drift diffusion model depends on how one wishes to reason about their target with the model. If the goal is to parsimoniously explain the speed-accuracy tradeoff, the appr...

super excited that the first paper from my PhD is now out! we develop a "philosophical toolkit" for computational cognitive modeling & use it to conceptually re-analyze a long-standing debate about evidence accumulation models of decision making 🧠📈 onlinelibrary.wiley.com/doi/full/10....

A schematic of our method. On the left are shown Bayesian inference (visualized using Bayes’ rule and a portrait of the Reverend Bayes) and neural networks (visualized as a weight matrix). Then, an arrow labeled “meta-learning” combines Bayesian inference and neural networks into a “prior-trained neural network”, described as a neural network that has the priors of a Bayesian model – visualized as the same portrait of Reverend Bayes but made out of numbers. Finally, an arrow labeled “learning” goes from the prior-trained neural network to two examples of what it can learn: formal languages (visualized with a finite-state automaton) and aspects of English syntax (visualized with a parse tree for the sentence “colorless green ideas sleep furiously”).

🤖🧠 Paper out in Nature Communications! 🧠🤖

Bayesian models can learn rapidly. Neural networks can handle messy, naturalistic data. How can we combine these strengths?

Our answer: Use meta-learning to distill Bayesian priors into a neural network!

Prefrontal encoding of an internal model for emotional inference Nature - Neurons in the rodent dorsomedial prefrontal cortex encode a flexible internal model of emotion by linking directly experienced and inferred associations with aversive experiences.

I’m excited to share a new paper from the lab. The study led by Xiaowei Gu reveals how the mPFC encodes complex emotional memories, using an internal model to infer emotional associations and memories via projections to the amygdala. a🧵(1/8)

Systems consolidation reorganizes hippocampal engram circuitry Nature - A study shows that loss of memory precision associated with systems consolidation can be explained by neurogenesis-dependent reorganization of engram circuitry within the hippocampus over...

Sharing a new paper from the lab. This paper, led by Sangyoon Ko, represents a merging of two longstanding research themes in the lab-- adult neurogenesis and systems consolidation.

A prospective code for value in the serotonin system - Nature Merging ideas from reinforcement learning theory with recent insights into the filtering properties of the dorsal raphe nucleus, a unifying perspective is found explaining why serotonin neurons are ac...

I'm excited to share that the last chapter of my PhD thesis is now published in Nature! 🍾

What drives serotonin neurons? We think it's the expectation of future reward and --- critically --- how fast this expectation is increasing. 📈
