The primary visual cortex (V1) is fundamental for visual processing. Transcriptomics suggests that the microcircuit in V1 consists of many inhibitory and excitatory cell types1. However, exactly how those diverse cell populations participate in visual cognition in vivo is unknown. To address this question, we recorded from V1 of two anesthetized monkeys using high-density Neuropixel probes across all layers of cortex2. We identified single neuron waveforms using Kilosort2, followed by rigorous manual curation. Our final dataset was composed of 801 negative spiking neurons (from 2529 units, 5 s

Grid cells in the medial entorhinal cortex (MEC) of mammalian brains show hexagonal firing fields and are thought to encode the animal’s current location in the environment. As the animal moves, grid cells integrate self-motion cues to track the current position relative to a starting reference location. Recent experiments have identified a class of predictive grid cells that encode the animal’s upcoming location 1,2. Continuous attractor networks (CAN) explain how grid cells develop their characteristic hexagonal firing pattern and enable path integration. But how does predictive coding arise
