Neurobiology research highlights role of inhibitory synapses in learning

New neurobiological research is shifting the understanding of how the brain learns. While traditional views focused on excitatory synapses—the systems responsible for neural activity and building new connections—recent studies from the Leibniz Institute for Neurobiology in Magdeburg suggest that the brain also stabilizes itself through inhibitory processes.

Researchers at the Medical University of Wroclaw, supported by the National Science Centre, are investigating the role of GABAergic inhibitory synapses. These synapses are highly plastic and play a crucial role in memory formation. Using optogenetics, research teams are exploring how these inhibitory circuits interact with excitation to shape cognitive functions.

Studies also highlight the importance of the BTSP mechanism, which links stimuli separated by several seconds, and note that learning is further enhanced by behavioral factors such as repetition, deep sleep, physical exercise, and dopamine release in response to novel stimuli.
