Terms of Use

Visual Neuroscience is a free educational atlas of the human brain: this website, the iPhone, iPad, Mac and Android apps, the Apple Vision Pro app and the MCP server that answers from the same data. It is made by Fadil Karim, who is “we” below. Using any of them means you accept these terms. They are short, and written to be read; what is collected about you, which is very little, is the privacy policy, a separate page.

What this is

A reference for study. The pages draw published atlases and summarise published work, and each says where its data came from and where the evidence stops. Nothing here is medical advice, a diagnosis, a treatment or a medical device. It is not a substitute for a doctor, and it must not be used to make decisions about anyone’s health. If someone is unwell, speak to a clinician; in an emergency, call the emergency services.

The anatomy is approximate by nature: atlases are averages, region borders are conventions, and the receptor densities and network states come from studies of particular groups of people with the caveats their sources give. We correct errors when we learn of them, and we would rather hear of one than not, but we cannot promise that everything is right or complete.

Using it

Everything is free, and nothing needs an account. You may use the site, the apps and the MCP server for your own study, teaching and research, in any way that does not harm the service or other people. You may not try to break into it, overload it, scrape it at a rate that slows it for others, pass off its answers or its content as your own, or use it for anything unlawful. The site and the apps are made for students and professionals; they are not directed at children.

Accounts

An account is optional. It keeps your saved models and your practice progress so that the same work is there on the web and in the apps. If you make one, give an email address that reaches you, keep your sign-in to yourself, and choose a username that does not impersonate anyone or offend. One account is one person. You can see everything it holds, download a copy of it and delete it at any time, on the account page or from the account box on any page; the deletion page gives the steps for every platform. We may suspend or delete an account that is used to break these terms.

What you save to an account, the models and their names and your progress, is yours. We store it only to give it back to you, we show it to no one else, and it goes when the account does.

The material and its licences

The text, drawings, interface and code of Visual Neuroscience are © Fadil Karim. You may quote and reproduce them for study and teaching with attribution to Visual Neuroscience; anything beyond that needs our written permission.

Much of what the pages draw belongs to others and comes under their own licences, which these terms do not change. The textbook is adapted from OpenStax under CC BY-NC-SA 4.0; the in vivo receptor maps are the Hansen et al. compilation under CC BY-NC-SA 4.0 and the autoradiography is Zilles and Palomero-Gallagher under CC BY 4.0; the AAL atlas, the MNI152 template, the HCP1065 tractogram and the Brodmann atlas are used under their own terms, the Brodmann diagram by permission of IFEN, and the viewers are built on NiiVue and three.js under their open licences. Each page names its sources, the About and Reference panels say more, and anything you take from those sources you take under their licence, not ours.

The MCP server

The server at mcp.visualneuroscience.ai answers questions from assistants that speak the Model Context Protocol, from the same public data as these pages, and the four account tools act on your own account only after you sign in and press Allow. It is offered as it is: we may change its tools, its address or its answers, or withdraw it, and an assistant’s own words around its answers are the assistant’s, not ours.

The apps

The apps are the same site, carried inside them. The app from the App Store is licensed to you under Apple’s standard Licensed Application End User License Agreement, which governs the licence of the app itself where these terms say less; Apple is not responsible for the app or its content, and has no obligation to support it. The app from Google Play comes under Google Play’s terms in the same way. In both, these terms govern the content and the services.

Posters

The posters are physical prints, sold and delivered by a print-on-demand shop run by a separate business, named on that page. A purchase is a contract with that shop under its own terms of sale, which are shown at its checkout: it takes the payment, prints and posts the poster, and handles delivery, returns and refunds, including the fourteen days a consumer in the United Kingdom has to cancel a distance sale. Nothing is bought through the app itself, and no in-app purchase is involved. The posters carry the credits their sources ask for; the data they draw on remains under the licences named on the posters and on the posters page.

Availability and changes

We may add, change or remove features at any time; every release is recorded in the ledger on GitHub, and the apps carry the version they were built from. We do not promise that the site or the server will always be up, and we may take them down for maintenance or for good.

No warranty, and the limit of our liability

The site, the apps and the server are provided as they are and as available, without warranty of any kind, express or implied, including that they are accurate, complete, fit for a particular purpose or free of errors. To the fullest extent the law allows, we are not liable for any loss or damage arising from your use of them or your reliance on anything in them, including indirect or consequential loss. Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be excluded under the law of England and Wales, and nothing in them affects the rights you have as a consumer under the law where you live.

Ending

You may stop using the site and the apps at any time, and delete your account at any time. We may end your access, or your account, if you break these terms, and we may end the service as a whole with notice on the site.

The law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction over any dispute, except that if you live elsewhere and the law there gives you the right to bring a claim at home, you keep it.

Changes to these terms

If these terms change, the date below changes with them, and a change that matters is announced on the site. Using the site or the apps after a change means you accept the terms as changed.
