The human brain has the ability to recognize and process a very wide range of sensory stimuli, from which it builds a mental representation. But do these representations change over time? Can we learn to classify and interpret stimuli more effectively?
Neuroscientists at the University of Geneva (UNIGE) have been trying to answer these questions by studying the olfactory system of mammals. They have succeeded in identifying the complementary role played by two distinct kinds of neurons in processing olfactory information and the different brain re-organization that occurs depending on the context.
After having previously demonstrated the possibility to boost the capacity to distinguish similar smells by regulating the inhibition of certain neural networks, the scientists now explain why the brain has to make use of different sorts of cells to form, maintain and reshape the representations of odors. In fact, it is their very combination that enables us to recognize and distinguish similar smells. Find out more about the research outcomes in the journal Neuron.
