Key result
Glutamatergic co-stimulation enhances GABAA-dependent Cl- influx in mature neurons and suppresses Cl- efflux in immature neurons.
Why the study?
How intracellular chloride concentration changes depend on properties of glutamatergic inputs and their spatiotemporal relation to GABAergic stimuli was unknown.
Population
Compartmental biophysical models simulating a simple ball-and-stick topology or a reconstructed immature CA3 neuron
Comparison
Glutamatergic co-stimulation vs GABAergic stimuli alone across varied input properties
Design
Computational simulation study

Should not change clinical practice; hypothesis-generating for short-term GABAergic plasticity in the CNS.
Glutamatergic co-stimulation alters GABAergic Cl- fluxes and affects the strength of GABAergic inhibition, acting as a relevant factor of short-term plasticity in the CNS.
Lombardi et al. (2020) studied this question. Glutamatergic co-stimulation vs. GABAergic stimulation alone was evaluated on GABAA receptor-dependent Cl- influx and efflux. Coincident glutamatergic depolarizations enhance GABAA receptor-dependent Cl- influx in mature neurons and suppress Cl- efflux in immature neurons.
