Here, we identified a circuit, locus coeruleus descending noradrenergic neurons projecting to the spinal dorsal horn (LC →SDH -NA neurons), that is activated by acute exposure to restraint stress and ...

Here we introduce a method to address this limitation and achieve ULM imaging in awake mouse brain. Pupillary monitoring was used to support the presence of the awake state during ULM imaging.

Both drugs clear the brain of a substance called beta-amyloid, which forms the sticky plaques associated with Alzheimer's. Studies show they can slow down the underlying disease process that ...

Neuralink's brain implant chip, 'the Link,' connects human brains to computers, aiding those with paralysis in movement control. Neuralink’s brain implant chip is a bold step toward merging ...

There are two Grok-3 reasoning modes available: “Think”, which will display Grok’s reasoning as it resolves requests; and “Big Brain” for complex tasks that require more computational power.

But what are the brain effects we can expect as the global population continues to outsource more and more of its cognitive function? Does AI accelerate humanity towards Idiocracy faster than Mike ...

Introduction: The locus coeruleus (LC)—noradrenaline (NA) system plays a crucial role in modulating neuronal excitability and plasticity. In epilepsy, the LC-NA system plays an important role in ...

One of the most significant discoveries in the study was the identification of two mouse strains that closely ... Since the retina is a direct extension of the brain, understanding how it ages ...

moment for more than a century, and it is finally within our grasp. We now know where it happens in the brain and when it’s more likely to happen. And we’re discovering some surprising ...

You may even struggle to find a simple word during a conversation. Sound familiar? Occasional memory slips are normal, yet it’s never too early to protect your brain health. Here are five ways to ...

The researchers then used their optimized technique to cool slices of the hippocampi of mouse brains to -196°C with liquid nitrogen ... All the results were similar to those seen in non-cryopreserved ...
