Brain.js - a tutorial environment for cognitive neuroscience
This is a demo copy: you can record from neurons in V1 or MT by placing an electrode into these areas. Press 'h' at any time to access a help window.
Brain has two views: the Brain viewer (left) and the stimulus and electrode recorders (right).
The menu at the top switches between the views
When in the brain viewer, you can scroll through the lateral and medial surfaces of the brain by clicking and dragging, or by swiping horizontally.
Add electrodes by pressing the buttons in the electrode panel. Drag and drop electrodes to place them on the brain.
In this demo we've made available only two cortical areas: V1 and MT. Click the brain viewer at any time to highlight these areas.
In the stimulus and electrode recorder view you will see the neural activity that is being recorded by your electrode.
To create a stimulus you can press the key m for motion.
Drag the motion stimulus to where you want it. Click to open the parameter panel and press the corresponding keys (q/a, w/s, or e/d) to adjust.
This is just a demo version of Brain. The full version we use for tutorials includes many more cortical areas, the ability to add top-down priors (spatial or feature-based attention), and to explore the functioning of other regions such as the somatosensory cortex and motor output regions.
