In a study published in the journal Nature Neuroscience, CNCB scientists report that a key to forming distinct associative memories lies in how sensory information is encoded in the brain. In many higher brain centres, sensory information is encoded ‘sparsely’, meaning that out of a large population of nerve cells, or neurons, only very few fire electrical impulses in response to any particular sensation.
