The BAR consists of a pretext model and a downstream model , with a shared brain anatomy-guided encoder for MRI feature extraction. The pretext model also contains a decoder for brain tissue segmentation, while the downstream model relies on a predictor for classification. We first train the ...
Magnetic Resonance Imaging (MRI) has assumed a central role in the investigation of the brain anatomy and function. This role can be attributed to, amongst others, its multimodal capabilities and the ability to study different tissues and their properties by acquiring different contrasts exhibiting hi...
We are formalizing these developments to produce a web-based ontology-linked atlas in which gross brain anatomy is defined, in part, by labeled volumes in a standard reference brain. We have developed new relations that allow us to use this well-defined gross anatomy as a substrate to define...
The positive physiological effects of hope are well-documented, most recently by CNN in 2013 in Jerome Groopman’s “The Anatomy of Hope,” where he writes:“Researchers are learning that a change in mind-set has the power to alter neurochemistry.”His research also showed that during the c...

gene expression data can be very valuable in identifying the molecular basis of brain organization. Similarly, Goel et al. (2014) used a combination of dimensionality reduction and spectral clustering to investigate the correspondence between spatial clusters of gene expression and human brain anatomy....
membrane potential during the interspike intervals within the burst. Here we perform a bifurcation analysis of a slightly modified version of that model to elucidate the mechanism in a reduced single-compartment model, and then we show that it is viable in a morphologically realistic model as well...
Regarding anatomy of efferents alone, our finding that the projections from SNc DA neurons to the DMS and DLS arise from distinct locations within the SNc is not inconsistent with several previous findings. For example, in rats that had the DA neuron toxin 6-OHDA injected into the DLS, degene...
To simulate neural activity, we used the laterality encoding model in Eq. (4) where we varied the directional tuning correlation between the hands and the size of the laterality dimension (as labeled along the x- and y-axes of Fig. 3d, e). We began by generating a synthetic target datas...
For the above-mentioned reasons, brain anatomy is revealed more clearly in T2w than in T1w images in neonate and early infant brain images and T2w images are considered the primary images for anatomical segmentation14. Although it is important to process T2w infant brain images, the ...
