To stop unwanted thoughts, the PFC sends a control signal to the hippocampus (brain's memory retrieval center). This activates local inhibitory interneurons (GABA), which then suppresses retrieval. Difficulties in this pathway may underlie #PTSD, #OCD, anxiety, and #depression.

New habits move from the Prefrontal Cortex (conscious effort) to the Basal Ganglia (habit loop). A trick is to automate the first 30 seconds of a habit, minimizing the PFC's required 'energy' for initiation until the Basal Ganglia takes over. #LifeHacks #SelfImprovement #Brain

The brain uses orthogonal sub-dimensions in neural space as communication channels. This is a great new paper using Neuropixels from ~6500 neurons on 8 cortical and deep regions in mice. Simplifying the space helps a lot to understand the idea. Here is my toy model and notes:

Dopamine ≠ reward but turns out, also not the learning molecule we thought. If DA RPE is the emperor, this work SCREAMS it was running naked all the time. This paper got quite some attention recently. Let me explain why it is so relevant. Here is my toy model and notes:

A core function of cortex is predicting what happens next given the world's state. This great recent paper from Oxford shows how cortical layers may use a clever delay trick to learn to predict. A simple illustration can explain the main idea. Here is my toy model and notes:

Decisions under uncertainty are a coordinated action of PFC, pre/motor, BG, and thalamus. This model could explain decision-making and impairments by hyperactive D2 receptors. We can clarify the paper by building a mouse with schizophrenia. Here is my toy model and notes:

This paper may solve a core neuroscience question of the last decades: What is the cortical code? Cognitive cortex also uses tuning, and latent variable span a non-linear manifold. Unlocking this work requires understanding why PSTHs are bad. Here is my toy model and notes:

Dopamine (DA) in the dorsolat. striatum (DLS) is a teaching signal that shapes learning. DA in DLS ≠ RPE but = to stimulus-choice associations relevant to a learning strategy. This can be beautifully explained as saddles in a loss landscape. Here is my toy model and notes:

To plan the future, the PFC represents a step-by-step map of actions, and at every step, this plan moves to the past like a conveyor belt. This proposes a super simple neural-subspace architecture for planning. A toy environment can clarify it. Here is my toy model and notes:

Researchers were able to freeze learning in mice. This great recent work shows the striatum is required for skill learning but not skill use (through optogenetics). Understanding the memory-making mechanism helps understand the core idea. Here is my toy model and notes:
