Too much noise can not only damage your ears but it can also adversely affect our brain development, finds a recent study that was published in an online journal known as eLife. These are the 7 everyday things that are silently killing your brain.

During development, RA is an important secreted molecule that aids in the proper organization of the brain. The cellular response to RA depends upon its concentration, which is determined by its production, movement through tissue and interactions with many proteins within the cell. During normal development, cells can filter the “noise” in RA levels and establish appropriate brain organization.

Researcher Thomas F. Schilling and lead author Julian Sosnik wanted to measure the fluctuations in RA and determine how cells respond to the proper amount despite the presence of constant noise.

The team used fluorescence lifetime imaging to exploit the auto-fluorescent nature of RA and measure its distribution across the developing zebrafish embryo. They found that RA forms a gradient in the embryo, with a lower concentration at the head. They also observed that a large amount of noise exists within the RA gradient.

They identified one protein within developing cells that interacts with RA to help reduce the noise. When this protein was altered, cells could no longer control the level of noise within the RA gradient, which led to disruptions in brain organization.

With this, the researchers concluded that noise reduction within cells is critical for the proper response to the RA gradient and normal organization of the brain. Read: Your decisions depend on the background noise in your brain.
