Interactive 3D models of human joints, showing how common medical complaints have arisen and how we are likely to evolve in the future, have been created at Oxford University.

The researchers created 3D computer models of human joints by compiling 128 slice CT scans of bones from humans, early hominids, primates and dinosaurs. In all, they scanned 224 bone specimens.

By using 3D engineering and mathematical methods the group have produced 3D 'morphs' to plot changes in the shapes of species throughout the human lineage. This has provided new insights into the morphological trends associated with common orthopaedic complaints, such as anterior knee pain and shoulder pain.

New evidence for how our brains handle surprise

A new study from the Bruno Group is challenging our perceptions of how the different regions of the cerebral cortex function. A group of ‘quiet’ cells in the somatosensory cortex that rarely respond to touch have been found to react mainly to surprising circumstances. The results suggest their function is not necessarily driven by touch, but may indicate an important and previously unidentified role across all the major cortices.

Language learning difficulties in children linked to brain differences

A new study using MRI has revealed structural brain changes in children with developmental language disorder (DLD), a common but under-recognised difficulty in language learning. Children with DLD aged 10-15 showed reduced levels of myelin in areas of the brain associated with speaking and listening to others, and areas involved in learning new skills. This finding is a significant advance in our understanding of DLD and these brain differences may explain the poorer language outcomes in this group.

New research reveals relationship between particular brain circuits and different aspects of mental wellbeing

Researchers at the University of Oxford have uncovered previously unknown details about how changes in the brain contribute to changes in wellbeing.

Night-time blood pressure assessment is found to be important in diagnosing hypertension

Around 15% of people aged 40-75 may have a form of undiagnosed high blood pressure (hypertension) that occurs only at night-time. Because they do not know about this, and therefore are not being treated for it, they are at a higher risk of cardiovascular disease such as stroke, heart failure, and even death, suggests new research from the University of Oxford published in the British Journal of General Practice.
