The Allen Institute recently released multiple free resources focusing on the structure and function of brain circuits. These resources include data, associated analysis software, and models integrating the data to enable bio-realistic simulations. They provide a powerful ecosystem for a new generation of analyses, theory, and modeling in computational neuroscience.
We will introduce several of these resources in a series of 1-hour sessions. Each session will include a scientific introduction for the resource and an online demonstration of accessing and analyzing the data.

-
Synaptic Physiology [1]. This dataset describes >1,500 synapses from mouse and human cortex. Measured properties include connectivity, synaptic strength, variance, and short-term plasticity. Cells are classified by their layer, transgenic markers, morphology, and intrinsic physiological features, allowing comparisons between many cell subclasses.
-
Visual Coding 2-photon [2]. This dataset contains 2-photon calcium imaging data that surveys visual responses across 6 cortical areas, 4 cortical layers, and 14 transgenically defined cell populations. Activity was imaged in awake mice in response to a variety of stimuli, while tracking the mouse’s running speed and pupil size in each session.
-
Visual Coding Neuropixels [3]. This dataset includes spiking activity from neurons recorded across more than dozen brain regions while mice viewed diverse visual stimuli. Each experiment includes spikes from hundreds of simultaneously recorded neurons, as well as local field potentials.
-
PatchSeq Characterization of Cell Types [4]. This dataset describes >4,000 cells from the mouse and human cortex. Intrinsic electrophysiological properties, morphologies, and transcriptomic profiles are measured from the same neurons, and types are assigned to those cells based on different properties.
-
Visual Behavior [5]. This dataset contains 2-photon calcium imaging recordings from transgenically defined cell populations across two cortical regions while mice perform a visual change detection task. Each experiment includes the activity of individual neurons and behavioral data.
-
Bio-realistic model of the mouse primary visual cortex [6]. The model integrates data from the Allen Institute and the literature on composition, connectivity, and in vivo activity of cortical circuits.
