Brain Connectivity (IMAGE) Allen Institute Caption The image shows a single section from a mouse brain. Neurons in one layer of sensory cortex (the very dense yellow color on the right) were labeled with green fluorescence to trace all the pathways arising from these cells across the brain. When these axons reach their cortical targets, they form synapses across the layers of the cortex with distinct patterns associated with the direction of information routing.
