A new method utilizing a biocompatible nanosheet incorporated into light-curable resin (NIRE method) has been proposed to construct large cranial windows over the cortex and cerebellum suitable for long-term imaging in awake mice. The NIRE method produced windows that maintained transparency for over 5 months and suppressed motion artifacts, enabling the visualization of neural structures and intracellular Ca2+ concentration changes at various scales, from populations of over a thousand neurons to single spines, in living mouse brain. This method allows for multi-scale in vivo imaging of neuronal morphology and intracellular calcium in awake mice, demonstrating its potential for studying brain function and pathology.

Scientists have developed a high-resolution magnetic resonance imaging (MRI) technique that is 64 million times sharper than normal, allowing them to take high-definition images of a mouse brain. The technology could help detect changes to the human brain due to neurodegenerative diseases such as Alzheimer's disease and changes linked to healthy aging. The researchers used a high-powered 9.4-tesla magnet, gradient coils that are 100 times stronger than current models, and a high-speed computer to create the souped-up MRI. The technique could also be useful for studying how the brain changes when mice are put on specific diets or given drugs in an effort to extend their life spans.

Researchers from multiple universities have made a breakthrough in MRI technology, capturing the sharpest images ever of a mouse brain. This refined MRI, combined with light sheet microscopy, provides an unprecedented way to visualize the brain’s connectivity, potentially leading to a better understanding of neurodegenerative diseases in humans. The refined MRI provides an important new way to visualize the connectivity of the entire brain at record-breaking resolution. The researchers say new insights from mouse imaging will in turn lead to a better understanding of conditions in humans, such as how the brain changes with age, diet, or even with neurodegenerative diseases like Alzheimer’s.
