Resting-state MEG-activity and MRS-GABA/Glx measurements reveal that there is a significant shift in excitability during the course of schizophrenia, involving hyperexcitability during the onset and a reduction at chronic stages.
Computational modeling and analysis of mouse neural population data finds that the excitation/inhibition imbalance theory of brain disorders is too limited to account for key changes in neural activity statistics.

A new molecular mechanism involving microRNA, which controls synaptic transmission in a specialized type of inhibitory interneurons in the hippocampus and short-term memory in mice, was identified.

Computational modeling revealed that balanced assemblies of excitatory and inhibitory neurons shape representational manifolds in olfactory cortex-like recurrent networks, resulting in joint maps of sensory and semantic information.

Multiverse analysis of the aperiodic component of the electroencephalography (EEG) power spectrum yielded robust evidence against a relationship to chronic pain, guiding further research on EEG biomarkers of chronic pain.

Translationally active polysomes from mammalian cells/tissues are successfully separated with rapidity, high efficiency and exceptional reproducibility by a SEC-based approach, an accessible alternative to the conventional sucrose density gradient analysis.

The slope of the power spectrum of subthalamic local field potentials tracks pathological states in Parkinson’s disease and likely complements beta activity as a feedback marker for adaptive deep brain stimulation.
Glucocorticoids are assumed to reflect 'stress,' but they increase proportionally to the increase in metabolic rate induced by stressors, leading us to propose that glucocorticoids reflect metabolic rate, not stress.

Spiking networks compensate the loss of neurons instantaneously, when restoration of excitatory/inhibitory balance becomes equivalent to restoration of functionality.
The synaptic structure in mouse V1 is explained by a synergy of homeostatic plasticity in incoming and outgoing synapses of inhibitory interneurons, establishing a stimulus-specific balance of excitation and inhibition.
