Understanding more the brain complexity


A brain implant could help regain the ability to make decisions, a process that may be lost after a stroke or brain injury, restore the neural mechanisms necessary for this process. According to a study published in the Journal of Neural Engineering, the placement of a neural device in the frontal lobe of a group of brain-injured monkeys succeeded in recovering, and even improving, their ability to make decisions.

Researchers at the University of Kentucky and the University of Southern California (USA) seem to have taken a key step towards the recovery of specific brain functions in patients with brain injuries. The study was based on a neural prosthesis implantation which evaluated the ability of neuronal communication in the brain of animals. 

Once that scientist obtained enough information about neuronal signaling and how this affected memory and recovery processes related to decision-making ability, they devised a model of multiple input, multiple output (MIMO) which stimulated those signaling neuronal pathways which had been and were necessary for the decision-making processes. The results showed that the MIMO model was highly effective in recovering the task performance capabilities and it was even able to improve performance in normal condition.
