Explore the brain from the palm of your hand! Learn about the structure and function of the human brain by interacting with high-resolution rotatable 3D models in real-time like you've never seen it before!
Brain Tutor HD uses rendered head and brain models as well as fiber tracts that were created from magnetic resonance imaging (MRI) scans of a study volunteer. The MRI data allows to look "inside" the brain using real-time slicing at millimeter resolution. For students, cognitive neuroscientists, medical professionals and everyone interested in the brain, the program provides information about the anatomy and function of the human brain with various atlases describing and visualizing lobes, gyri, sulci, Brodmann areas, subcortical structures, selected specialized functional areas and major fiber tracts.

With Brain Tutor HD you can:
* Explore high-resolution 3D models of the head and brain in real-time.
* Visualize major white matter fiber tracts.
* Slice the brain along three axes (sagittal, axial and coronal).
* View MRI brain slices at millimeter resolution.
* Learn from text information about the functions of selected lobes, gyri, sulci, subcortical structures, Brodmann areas, functional areas and fiber tracts.
* Learn where brain structures are located both within 3D brain models as well as in MRI slices.

To get started:
* Tap on a 3D brain model to reveal a brain area at that location.
* Switch to another atlas and a specific brain area or fiber tract using the navigation tables.
* Select a 3D model (brain hemisphere, head) with the tab bar buttons at the bottom.
* Pan with one finger to rotate a brain model.
* Pan with two fingers to move a brain model.
* Use pinch gesture to zoom a brain model.
* Select the head model to switch to head slicing mode.
* Switch between navigation and slicing mode with two icons on right side in the top bar.
* In head slicing mode, pan with one finger to move the slicing plane.
* Tap on a slicing direction icon in the top bar to switch between three orthogonal slice planes.
* Tap on text icon (iPhone/iPod Touch) or info icons in brain areas/tracts table to view text information about selected brain structure.

What’s New

Version 2.1

This is a major universal update of Brain Tutor 3D now supporting also the iPad. As in version 1.0, you can learn about the structure and function of the human brain by interacting with rotatable 3D models in real-time. Brain Tutor 3D now uses a modernised user interface and provides high-resolution brain models. While the app is still free, this version provides new atlas types for subcortical structures, functional areas and fiber tracts that can be obtained via in-app purchases.

Very nice

$3 for the add-ons is well worth it, and provides lots of extra hi-res detail.

Excellent cortical anatomy

Well obviously, this app leaves out a fair amount of gross neuroanatomy--but several other apps have it and the gross anatomy is honestly the easiest thing you encounter in neuro course; beyond that the difficulty and detail ramps up and your teachers (points to self) consipre to fail you (if you dont learn the material of course).

I also notices the people givig this app 2-1 stars come off as dithering idiots when I read their reviews. Look a few down from this one: someone claims it deserves 1 star b/c it doesn't include the diencephalon! Woop de doo. It's an easy structure. Moreover he or she then fails epically via claiming the dienchephalon contains the, just wow. That's so assinine it makes my head spin--the cerebellum juts out from the brain's stalk at the level of the pons, i.e., the metencephalon. Had that showed up in my quiz stack, it would receive a fat red X. Yes it's bad BUT there are plenty of apps that will show you it. Because the incompleteness, I subtract 1 star.

TL;DR Good MRI view and cortical anatomy. Not much else though.

I am impressed with how this has improved my overall understanding of neuroanatomy. Thanks! STOP giving this app bad reviews, u get what u pay for. Honestly are u gonna sit down for a couple hours a day studying with ur iPhone? I paid 40$ for netters' neuro note cards App, and while They are very detailed, I have trouble spending more than 10 minutes a day while I'm taking a crap to study them. For example, my 10 mins today were spent writing this review ;-)

In all seriousness, to learn the brain this should be one of the last resources u use. Right now, I have an atlas, a textbook, a high yield neuroanatomy text, a couple hundred pages of lecture notes, online neurosullabus, online sylvius, netter's iPhone neuro app, and and a lab study guide. For a free app, this is a great tool to brush up on what u know, get used to MRI pics, and understand the brain in 3D. It would def. Pay for a detailed version that included the spinal cord, but for this free app there is nothing more I can ask for.
