Nat Neurosci: Study reveals mechanisms by neurons to transmit information

, March 20, 2020 /PRNewswire/ --- A recent study from the University of Rochester showed that certain neurons are skilled at helping individuals perceive the motion of an objectThese findings may have implications for the development of prosthesis and understanding of certain brain diseasesresearchers want to determine whether the brain must switch between each of the different neurons with a different fixed reference line (for example, between head-centered neurons and world-centric neurons), or whether neurons are flexible and update the reference line according to itMeet the transient needs of object motion tasks(pictured:, the researchers trained subjects to determine the movement of objects at head-centered or world-centric coordinates and switchbetween between tests based on tipsresearchers recorded signals from neurons in two different regions of the brain and found that neurons in the upper (VIP) region of the brain responded to the movement of objects with tasksIn other words, neurons do not have a fixed reference line, but are flexible in adapting to the requirements of the task and changing their reference systemaccordinglywhen subjects are asked to report the object's movement sorority relative to their head, neurons in the VIP represent the object's movement at head-centered coordinatesWhen subjects were asked to report the motion of an object relative to the world, they represented the movement of the object in the coordinates of the center of the worldbecause neurons respond so flexibly, this means that the brain can greatly simplify the process of transmitting the information needed to guide the movement"This study is the first to show that neurons can flexibly represent spatial information in different coordinate systems based on instructions to subjects," said de Angelis,This means that the brain can decode or "read" information from this single group of neurons and get the information it needs for any task"
this study provides important information about how the brain works and may help develop surgery such as neurorepair(Bio Valley Bioon.com)information source: Neurons sau shift how how material information about: study original origin: Ryo Sasaki et al, Flexible of the object object motion in multiple reference reference by parietal deframes neurons, Nature Neuroscience (2020) DOI: 10.1038/s41593-020-0656-0
