Maybe the most strange organ in the body, the brain continues to surprise researchers regardless of the numerous hours they’ve invested trying to analyze its inner operations. Each brand-new discovery about the brain brings a thousand brand-new concerns in its wake.
Here are 18 things we found out about the brain in 2023 that blew our minds.

1. Recently found part of the brain
In January, researchers explained their discovery of a kind of guard in the brain that assists remove waste and serves as a look-out post for immune cells. The thin guard appears to assist manage the circulation of proteins and particles in between various compartments including cerebrospinal fluid, a colorless liquid that streams around the brain and within tubes through the organ.
2. Squid and human brains connected by development
In spite of the 500 million years of advancement that different squids and human beings, our brains establish in a really comparable method to the brains of these cephalopods. Researchers found this by keeping track of stem cells called neural progenitor cells in establishing squid embryos. To develop a squid retina, where the majority of the animal’s neural tissue is discovered, the cells need to initially form a long, largely jam-packed structure that can likewise be identified throughout the neural advancement of vertebrates like us.
3. ‘Junk DNA’ and huge brains
The genes that made it possible for human beings to grow significantly huge brains might have initially originated from “scrap DNA,” which does not code for any proteins, scientists exposed early this year. Eventually in human development, after we divided from other primates, a few of this scrap DNA got the capability to encode proteins. In animal and lab-dish experiments, numerous of these genes appeared essential for enhancing brain development.
4. Injuries plugged with minibrains

Researchers utilized cerebral organoids– mini 3D designs of the brain– to fix brain injuries in rats. The organoids were grown from human stem cells and transplanted into rats’ visual cortices, the area of the brain where info from the eyes is at first processed. The scientists intend to ultimately use the strategy in people, however that’s several years away.
5. Native language wires the brain
An individual’s native language might affect how their brain connect information-processing centers within its structure, according to a research study of individuals whose native languages were German and Arabic released in February. Distinctions in the research study individuals’ brains were chalked up to linguistic distinctions in between the languages. More work is required to expose how cultural functions of discussion may form brain structure.
6. Psychedelics attack brain cells
Psychedelics have actually revealed guarantee as treatments for hard-to-treat anxiety,
