White matter fibres and brain, artwork

White matter fibres overlaid a 3d model of the human brain in top view. Coloured 3D diffusion spectral imaging (DSI) scan of the bundles of white matter nerve fibres in the brain. The fibres transmit nerve signals between brain regions and between the brain and the spinal cord. Diffusion spectrum imaging (DSI) is a variant of magnetic resonance imaging (MRI) in which a magnetic field maps the water contained in neuron fibers, thus mapping their criss-crossing patterns. A similar technique called diffusion tensor imaging (DTI) is also used to explore neural data of white matter fibres in the brain. Both methods allow mapping of their orientations and the connections between brain regions. Data/software: NIH Human Connectome Project /humanconnectomeproject.org)

Coat of arms 17th century Ridgeway and Chaffin

This image is from a copperlate engraving, and shows part of a roll of arms from Richard Blome's Britannia, an atlas published in 1673. It features the coats of arms of people who contributed towards the completion of the work a?? starting with King Charles II. Each page includes 35 coats of arms, presented here in pairs. These two coats of arms are from folio (page) 23 of the work. In old English, ans appeared as a longs (which looks like an f'), while ss appeared as fs'. Com was an abbreviation for County'. A number is assigned to each benefactor.Here are the accompanying texts (followed by modernised English where appropriate): 760. Ye Rt. Hon'ble Sr. Robert Ridgeway Kt. & Bart. Earle of LONDONDERRY & Baron of Gallen Ridgeway in ireland &ca at Torre in Com Devon & at Ballinakill in ye Queen's County in Ireland (The Right Honourable Robert Ridgeway; Earl of Londonderry and Baron of Gallen-Ridgeway; Torrington, Devon). 761.
