In a new scientific development, scientists growing miniature brains in a lab have created neural networks that act like those in the human brain.

According to researchers, the discovery will enable cheaper and easier research to combat brain diseases and drug development.

Researchers, in recent years, have been working towards creating small, three-dimensional human brains or cerebral organoids, with the hope that they will eventually replace animal models, imaging techniques and autopsies as the preferred mode for understanding the intricacies of the brain.

The simplified organoids mimic the brain's cerebral cortex, which is responsible for features like thinking, memory and language.

Speaking about it, Hideya Sakaguchi, of the Salk Institute of Biological Sciences in California said that the models have already been used to understand diseases such as microcephaly, Zika infection and glioblastoma, but little information is there on how to neurons within them communicate.

To investigate, researchers from the Kyoto University took a ball of stem cells and grew an organoid with layered tissues that had a similar structure to the cerebral cortex.

After three months the researchers took individual cells from the tissue and grew them separately in another dish and they found that the cells began to organise themselves with other nearby clusters.

Following it, the team then studied calcium ion binding, a method of detecting neural activity, to see how and when the neurons within the clusters fired.

According to Sakaguchi, at first the neurons fired individually, but they soon formed networks and connections with other neurons and begin to operate in a synchronised fashion.

The discovery is important because synchronised neural activity is believed to be the basis of various brain functions, including memory.

Sakugachi days the neural networks will help with drug discovery, better modelling of neuropsychiatric disorders and perhaps eventually open the door to regenerating chunks of the brain after disease or physical trauma.
