The implants they created are so soft
Researchers found higher neuronal density and lower foreign body response
A team of researchers at Canada s McGill University has succeeded in developing a new method to create brain implants that are as soft as the brain tissue itself. The researchers used silicon and sugar to create delicate silicone implants, the softest brain implant to the day, as thin as sewing thread (nearly 0.2 mm). Its consistency, scientists say, will ensure they cause minimum irritation within the brain and reduce the foreign body response. The study was published in the Advanced Materials Technologies journal
Study shows how our brains sync hearing with vision News
To make sense of complex environments, brain waves constantly adapt, compensating for drastically different sound and vision processing speeds
Every high-school physics student learns that sound and light travel at very different speeds. If the brain did not account for this difference, it would be much harder for us to tell where sounds came from, and how they are related to what we see.
Instead, the brain allows us to make better sense of our world by playing tricks, so that a visual and a sound created at the same time are perceived as synchronous, even though they reach the brain and are processed by neural circuits at different speeds.

Instead, the brain allows us to make better sense of our world by playing tricks, so that a visual and a sound created at the same time are perceived as synchronous, even though they reach the brain and are processed by neural circuits at different speeds.
One of the brain s tricks is temporal recalibration: altering our sense of time to synchronize our joint perception of sound and vision. A new study finds that recalibration depends on brain signals constantly adapting to our environment to sample, order and associate competing sensory inputs together.
