BigBrain project creates 3D animation of human brain
Researchers at the Montreal Neurological Institute in Canada have created the most detailed 3D map of a complete human brain ever made by slicing a preserved brain into 7,400 sections, each no more than 20 micrometres thick. This video zooms in on layers of the BigBrain reference map to reveal detail in different regions including the corpus callosum, the basal ganglia, the insular cortex, the brainstem and the cerebellum.
as far as i can tell, this is an anatomical map, not a functional one (i.e. it will not tell you what your brain looks like when you’re doing X).
still pretty darn cool.
Magnetic Resonance Angiogram of the Brain
Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of the arteries in order to evaluate them for stenosis (abnormal narrowing), occlusion or aneurysms (vessel wall dilation that is at risk of rupture).

The mind reading trick, done before with objects, is now plumbing the depths of human feeling
Sorry, you cannot extrapolate internal states of being from fMRI. You can infer that activity in those areas is correlated with that internal state of being (but self reports suck anyways). Anything more than that is still BS.

Can you imagine the applications of 3D printing for visualizing complex biological structures? This is so neat:
The Sugar Lab is a micro-design firm for custom 3D printed sugar. With our background in architecture and our penchant for complex geometry, we’re bringing 3D printing technology to the genre of mega-cool cakes. 3D printing represents a paradigm shift for confections, transforming sugar into a dimensional, structural medium. It makes it possible to design, digitally model and print an utterly original sugar sculpture on top of a cake.

Fluorescence micrograph of a neuron regenerating in culture.
When cultured with growth factors in vitro, neural stem cells can generate neurons (red), as well as the cells that support them— astrocytes (green) and oligodendrocytes. In culture, neural stem cells group together in ball-like clusters, called neurospheres (bottom left). Neurospheres are of great therapeutic interest because they have the potential to regenerate and replace neurons lost in traumatic brain injury and neurodegenerative diseases, such as Parkinson’s disease, Alzheimer’s disease, and multiple sclerosis.
Image: This neurosphere (bottom left) was prepared from neural stem cells extracted from an embryonic rat midbrain. After allowing the cells to proliferate and expand for 7 days, they were imaged with confocal microscopy. Cells differentiated to neurons are labeled red with an antibody to βIII-tubulin, whereas astrocytes are labeled green with an antibody to glial fibrillary acidic protein (GFAP), an intermediate filament specific to astrocytes. All nuclei are stained blue with bisbenzamide
