Researchers in Switzerland previously showed that synaptic learning mechanisms in the brain’s cortex are dependent on feedback from deeper brain regions. They have now deciphered how this feedback gates synaptic strengthening by switching particular inhibitory neurons on and off. They have identified which neurons are involved in this mechanism in mouse. They will test their results in “real life” to check whether the inhibiting neurons will behave as predicted when a mouse needs to learn new sensory information or when it discovers new aspects in its tactile environment. The findings might be relevant for unsupervised learning which is important for the creation of efficient voice or face recognition programmes…read more. TECHNICAL ARTICLE
