Neural networks and brain imaging techniques



Neural networks and brain imaging techniques are at the forefront of cutting-edge research in neuroscience and technology, and recent advancements in these areas have made significant impacts.

Neural Networks and Brain Mapping: Researchers are utilizing advanced techniques like synchrotron X-ray tomography and volume electron microscopy to create detailed maps of brain structures. This allows scientists to visualize entire neural networks and specific cellular structures at nanometer resolution. The approach combines data from multiple imaging methods to produce comprehensive maps, which are valuable for studying neural circuits in mammals and potentially other tissues like cancer cells​ 


AI and Imaging Optimization: Artificial intelligence (AI) is revolutionizing the speed and efficiency of brain imaging. For instance, the SmartEM system leverages machine learning to expedite electron microscopy imaging, reducing the time required for projects that previously took weeks to just a few days. This technology makes high-resolution brain mapping more accessible and affordable, enabling detailed analysis at the synapse level, crucial for understanding psychiatric and neurological disorders​ ​.


Advancements in Functional MRI: Recent studies have used 7 Tesla resting-state functional MRI (fMRI) to explore the functional properties of brain networks involved in human consciousness. Researchers identified connections between the subcortical ascending arousal network and the cortical default mode network, which are critical for self-awareness and consciousness. These findings have implications for improving recovery strategies for patients with severe brain injuries​ ​.


Transparent Brain Implants: Innovative brain implants made from graphene are being developed to simultaneously record electrical signals and optically image neural activity. These implants are fully transparent, allowing for high-density electrode arrays that can capture detailed neural activity without obstructing optical imaging. This technology is expected to advance fundamental neuroscience research and potentially be used in clinical settings for better understanding and treating neurological conditions​ ​.

How chronic stress warps decision-making

Image
  Nerve-cell ‘highways’ identified in mice suggest that stress pushes the brain towards rigid habit and away from thoughtful choices. Scientists have found two ‘dials’ in the brain that help to explain how  chronic stress  hijacks decision-making 1 . The discovery is based on experiments in mice and will therefore need to be confirmed in humans. But it shows that prolonged stress dials back deliberate decision-making while also boosting an ‘autopilot’ mode in the brain that favours rigid, habitual behaviours. It’s long been known that humans who face chronic stress are prone to resort to a habit, such as smoking a cigarette or eating junk food, rather than make a well-thought-out decision. The work, reported today in  Nature , uncovers a biological mechanism for how stress puts its finger on the scale in favour of routine, scientists say. “It’s really a major achievement,” says Kyle Smith, a neuroscientist at Dartmouth University in Hanover, New Hampsh...
