Human brain

Understanding

• Key-value memory in the brain

Computational Analysis

Comparison to computer

• How (and Why) to Think that the Brain is Literally a Computer
• Contextual feature extraction hierarchies converge in large language models and the brain (LLMs are becoming more brain-like as they advance)

Biological vs. artificial neuron

• Single cortical neurons as deep artificial neural networks: Each biological neuron can be simulated using DNN of 5-8 layers
• Mapping Biological Neuron Dynamics into an Interpretable Two-layer Artificial Neural Network

Data processing

• Representational geometry: integrating cognition, computation, and the brain
• Language is primarily a tool for communication rather than thought
• The Unbearable Slowness of Being: Why do we live at 10 bits/s? (preprint)

Extract manifold/geometry

• Selection of experience for memory by hippocampal sharp wave ripples
