• The development of aperiodic neural activity in the human brain (2024, unknown): “…reductions in neural noise in childhood results in inefficient neural As individuals age, structural and functional changes in MFG (that is, synaptic pruning and changes in neurotransmitter levels (GABAergic interneurons and glutamate) 87 ) probably lead to a flattening of aperiodic slopes 88,89 .”
• Longitudinal trajectories of aperiodic EEG activity in early to middle childhood (2024, unknown): “As children continue to mature, ongoing network optimization may modulate the GABAergic and glutamatergic “push-pull” mechanism, resulting in a shift towards increased excitatory tone (Hill et al., 2022; McKeon et al., 2024).”
