Inside the egg

A 3D surface render from T1-weighted MRI scan. Playing with cut-outs and window options can be very helpful to get your head around (no pun intended) neuroanatomy, particularly in relation to cranial features. Rendered in the excellent MRIcroGL.

Covariance

Another MATLAB accident. This time, the covariance structure of a retinotopic mapping stimulus comes out as a wavy pyramid.

Retinotopic noise

Retinotopic mapping is an fMRI technique used to localise the visual areas of the brain, based on their topographic representation of the visual field. Here, polar angle representations show the horizontal meridian in blue and the upper and lower vertical meridians in red and green, respectively. This short movie illustrates the levels of noise observed when analysed with a phase-encoded Fourier transform approach.

Van Gogh

Another accidental image, this one reminds me of Vincent Van Gogh’s distinctive style.

Vesicles

A curious animation that produces the illusory percept of variable speed, with the dots seeming to travel faster at the mouth of circles than in the empty middle space.

Jagged edges

Visualisations in MATLAB hardly ever go as planned, but I love the way it throws in jagged edges and sharp colours when you don’t expect it. Here, the diffusion gradient directions of a dMRI sequence are visualised as a sphere.

Blueprints

The big idea behind the Human Connectome Project is to find the basic organising principles behind cerebral organisation, the blueprint of our brains, if you like. Either way, their data is stunning and this reconstruction may be what a blueprint of the mind will look like; only time will tell.

Messy cabling

I love this view of tract density imaging, which just makes the brain look like a tangled mess of electrical cabling.

Surfin' USA

Lazy Sunday afternoon, sunset over a Californian beach… is it all in the mind? Maybe, but this next image had me humming along to old Beach Boys songs.

Mandalas

While totally unintended, what started as stimulus design ended as colourful mandalas.

Wireframe

The wireframe of the mind? Probably not, but this rendering of the main white matter pathways in delicate, thin wires evokes the volume and presence of a whole human brain.

Filmstrip

A diffusion MRI tract density image. This visualisation is produced from virtual reconstruction of white matter fibres, but the twisting and turning of fibres is reminiscent of blunt dissection approaches.

Flower power

An accidental superposition, which reminded me 1960’s counterculture iconography.

Through the looking glass

Finding your way around is much easier when you have the right map. In this case, MNI coordinates are visualised as floating red spheres on a 3D rendered ‘glass’ brain.

A patchy mind

This is a non award-winning image I made for Research Images as Art, ran by the UCL Graduate School. It was a visually pleasing mistake in surface reconstruction with Freesurfer.
