brainglobe-heatmap

brainglobe-heatmap allows you to create heatmaps, mapping scalar values for each brain region (e.g., number of labelled cells in each region) to a color and creating visualizations in 2D (using matplotlib or 3D (using brainrender).

2D heatmap generated using matplotlib - adapted from Fig 1. from Hansen et al (2025)

3D heatmap generated using brainrender

Usage

For full documentation, please see the BrainGlobe documentation. Examples can be found in the examples directory of this repository.

Quickstart

Installation

pip install brainglobe-heatmap

2D heatmap

import brainglobe_heatmap as bgh

values = dict(  # scalar values for each region
    TH=1,
    RSP=0.2,
    AI=0.4,
    SS=-3,
    MO=2.6,
    PVZ=-4,
    LZ=-3,
    VIS=2,
    AUD=0.3,
    RHP=-0.2,
    STR=0.5,
    CB=0.5,
    FRP=-1.7,
    HIP=3,
    PA=-4,
)

f = bgh.Heatmap(
    values,
    position=5000,
    orientation="frontal",
    vmin=-5,
    vmax=3,
    format="2D",
).show()

3D heatmap

import brainglobe_heatmap as bgh

values = dict(  # scalar values for each region
    TH=1,
    RSP=0.2,
    AI=0.4,
    SS=-3,
    MO=2.6,
    PVZ=-4,
    LZ=-3,
    VIS=2,
    AUD=0.3,
    RHP=-0.2,
    STR=0.5,
    CB=0.5,
    FRP=-1.7,
    HIP=3,
    PA=-4,
)

scene = bgh.Heatmap(
    values,
    position=(8000, 5000, 5000),
    orientation="frontal",
    thickness=1000,
    vmin=-5,
    vmax=3,
    format="3D",
).show()
