A user-friendly python library to create high-quality, 3D neuro-anatomical renderings combining data from publicly available brain atlases with user-generated experimental data.

Documentation
brainrender is a project of the BrainGlobe Initiative, which is a collaborative effort to develop a suite of Python-based software tools for computational neuroanatomy. A comprehensive online documentation for brainrender can be found on the BrainGlobe website here.
Furthermore, an open-access journal article describing BrainRender has been published in eLife, available here.
Installation
From PyPI:
Quickstart
import random import numpy as np from brainrender import Scene from brainrender.actors import Points def get_n_random_points_in_region(region, N): """ Gets N random points inside (or on the surface) of a mesh """ region_bounds = region.mesh.bounds() X = np.random.randint(region_bounds[0], region_bounds[1], size=10000) Y = np.random.randint(region_bounds[2], region_bounds[3], size=10000) Z = np.random.randint(region_bounds[4], region_bounds[5], size=10000) pts = [[x, y, z] for x, y, z in zip(X, Y, Z)] ipts = region.mesh.inside_points(pts).coordinates return np.vstack(random.choices(ipts, k=N)) # Display the Allen Brain mouse atlas. scene = Scene(atlas_name="allen_mouse_25um", title="Cells in primary visual cortex") # Display a brain region primary_visual = scene.add_brain_region("VISp", alpha=0.2) # Get a numpy array with (fake) coordinates of some labelled cells coordinates = get_n_random_points_in_region(primary_visual, 2000) # Create a Points actor cells = Points(coordinates) # Add to scene scene.add(cells) # Add label to the brain region scene.add_label(primary_visual, "Primary visual cortex") # Display the figure. scene.render()
