Transparent heart tissue reveals hidden complexity

Transparent heart tissue reveals hidden complexity
A technique borrowed from neuroscience to see through brain tissue is helping scientists to see the fine structure of the heart. Using an existing approach, a team from Imperial has been able to turn samples of heart tissue transparent, revealing the complex networks of tiny blood vessels which supply the tissue as well as the scaffold of collagen which holds everything in place.

3D models of faces could help in reconstruction surgery

3D models of faces could help in reconstruction surgery
Researchers are scanning 6,000 volunteers for a project that aims to create 3D computer face models for reconstructive surgery. One of the current challenges for plastic surgeons is that they do not have guidelines for facial reconstruction procedures that take into account different ethnicities and age groups. This means that function can be restored to faces, but their features may not look natural in comparison to a healthy person of the same age and ethnicity.

Electricity improves short-term memory

Electricity improves short-term memory
Scientists have uncovered a method for improving short-term working memory, by stimulating the brain with electricity to synchronise brain waves. Researchers at Imperial College London found that applying a low voltage current can bring different areas of the brain in sync with one another, enabling people to perform better on tasks involving working memory.

Prosthetic arm tech detects spinal nerve signals

Prosthetic arm tech detects spinal nerve signals
Scientists have developed sensor technology for a robotic prosthetic arm that detects signals from nerves in the spinal cord. To control the prosthetic, the patient has to think like they are controlling a phantom arm and imagine some simple manoeuvres, such as pinching two fingers together. The sensor technology interprets the electrical signals sent from spinal motor neurons and uses them as commands.

Optogenetics fine-tuned

Optogenetics fine-tuned
Currently, optogenetics is a blunt-force instrument for manipulating neural activity, which limits its usefulness in the delicate environment of the brain. Researchers have demonstrated that optogenetics can be used as a finely tempered tool to observe and manipulate neural activity. Recent reports have emerged providing the opportunity to balance out excitation and inhibition of neural circuits using optogenetic techniques.

Wasps advance brain surgery techniques

A significant problem when operating on the brain is trying to reach a lesion whilst avoiding obstructions. A traditional straight needle insertion has the potential to injure an area, causing irreversible consequences, or the surgeon could deem it too dangerous to even attempt, resulting in an inoperable diagnosis. Imperial College, London has been working with maxon products to develop a groundbreaking robotic steerable needle.
