Experience and training are known to boost our skills and mold the brain's organization and function. Yet, structural plasticity and functional neurotransmission are typically studied at different scales (large-scale networks, local circuits), limiti

Learning improves perceptual decisions by enhancing the brain's ability to filter noise and irrelevant information. Here, the authors show that GABAergic inhibition in decision-making circuits supports our ability to optimize perceptual judgments thr

Learning and experience are known to improve our ability to make perceptual decisions. Yet, our understanding of the brain mechanisms that support improved perceptual decisions through training remains limited. Here, we test the neurochemical and fun

Interpreting cluttered scenes —a key skill for successfully interacting with our environment— relies on our ability to select relevant sensory signals while filtering out noise. Training is known to improve our ability to make these perceptual ju

The brain’s capacity to adapt to sensory inputs is key for processing sensory information efficiently and interacting in new environments. Following repeated exposure to the same sensory input, brain activity in sensory areas is known to decrease a

Murley et al. use ultra-high field (7T) magnetic resonance spectroscopy to measure in vivo glutamate and GABA in frontotemporal lobar degeneration syndromes, and show that deficits in these neurotransmitters are associated with behavioural disinhibit
