Scientists Can Image the Processing of Information Deeper in the Cortex With the Help of a New Multi Photon Microscope Design, Max Planck Institute Study

Visual and tactile objects in our surroundings are translated into a perception by complex interactions of neurons in the cortex. The principles underlying spatial and temporal organization of neuronal activity during decision-making and object perception are not all understood yet. Jason Kerr from Max Planck Institute for Biological Cybernetics in Tubingen, in collaboration with Winfried Denk from the Max Planck Institute for Medical Research in Heidelberg, now investigated how different sensations are represented by measuring activity in neuronal populations deep in the cortex. The scientists developed a method, with which they can study the neuronal activity in some of the deepest layers of the cortex in rodents, something that has not been possible up until now.
