NeuroGecko

Deep engineering system

Rotate and slice real brain scans in three dimensions right inside your presentation slides without crashing the browser.

NeuroGecko showing its interactive brain MRI volume slicer and slide deck controls

Current status

Open-source WebGL brain MRI presentation platform on GitHub for academic lectures and lab talks.

Overview

Web presentation platform built for neuroscience researchers to slice, rotate, and inspect real 3D MRI brain scans live inside browser slide decks.

Why it was built

Neuroscientists giving talks usually have to paste flat 2D screenshots into PowerPoint because embedding multiple 3D brain viewers in browser slides crashes graphics memory.

Why it helps

Automatically recycles 3D graphics memory as you flip between slides so speakers can explore live 3D brain volumes and poll the audience in real time without browser crashes.

What you can do

Live 3D MRI brain volume slicing and rotation directly inside presentation slides
Automatic WebGL graphics memory pooling for multi-slide 3D decks
Built-in live audience Q&A and interactive code demonstration slides
Open source and ready for academic lectures and lab meetings

SafeBrain WebGL Context Pooler & Interactive 3D NIfTI MRI Slide Decks

Lets neuroscience researchers rotate, slice, and window real 3D volumetric brain MRI scans live inside browser presentation slides alongside real-time Convex audience polling.

SafeBrain WebGL Pool

Single-Canvas Niivue Context Recycling Across 40+ Slides

Reuses a pooled WebGL2 rendering context across slide transitions so multi-volume neuroimaging talks never exhaust browser GPU context limits (typically capped at 8–16 contexts).

NIfTI Volume Slicer

Live Axial, Sagittal, Coronal & 3D Render Clipping Planes

Supports real-time multi-planar MRI/fMRI slicing, colormap windowing, and cortical mesh overlays directly inside Spectacle presentation slides.

Convex Live Polling

Real-Time Audience Q&A & Interactive Lab Quizzes

Synchronizes speaker slide state with audience devices via Convex so attendees can vote on neuroanatomy prompts and submit questions live.

Executable Code Slides

Embedded Sandpack & Analysis Notebook Demonstrations

Pairs 3D brain volumes with live interactive code sandboxes for reproducible neuroimaging methods lectures.

Before & After Engineering Audit3D Neuroimaging Presentation Platform1 pooled WebGL2 canvas across 40+ slides · Live 3D NIfTI slicing

SafeBrain pooled WebGL 3D NIfTI MRI slides vs. flat 2D screenshots or GPU context loss

Comparison focus

Before: Browser CONTEXT_LOST_WEBGL after 8–16 3D slides or flat 2D screenshots

Browsers cap active WebGL contexts at 8–16 per tab; mounting a new 3D brain viewer per slide drops the GPU context mid-lecture, forcing researchers back to static 2D images.

// Naive per-slide 3D viewer mount
slides.map(s => <NiivueCanvas volumeUrl={s.nifti} />)
// Slide #12 -> WebGL: CONTEXT_LOST_WEBGL: loseContext: context lost

After: SafeBrain single-canvas WebGL context pooling across 40+ live 3D MRI slides

NeuroGecko's SafeBrain architecture recycles a pooled Niivue WebGL2 canvas across slide transitions with sub-frame NIfTI volume swapping and real-time Convex audience polling.

// NeuroGecko SafeBrain Pooled WebGL Lifecycle

  <ActiveSlideNiftiViewer volume={currentSlide.nifti} plane="axial+3d" />
</SafeBrainPool> // 1 pooled GPU context recycled across all 40+ slides
