• Kainate receptors (KARs) are highly expressed in the immature brain and have unique developmentally regulated functions that may be important in linking neuronal activity to morphogenesis during activity-dependent fine-tuning of the synaptic connectivity. Altered expression of KARs in the developing neural network leads to changes in glutamatergic connectivity and network excitability, which may lead to long-lasting changes in behaviorally relevant circuitries in the brain. Here, we summarize the current knowledge on physiological and morphogenic functions described for different types of KARs at immature neural circuitries, focusing on their roles in modulating synaptic transmission and plasticity as well as circuit maturation in the rodent hippocampus and amygdala. Finally, we discuss the emerging evidence suggesting that malfunction of KARs in the immature brain may contribute to the pathophysiology underlying developmentally originating neurological disorders. This article is part of the special Issue on ‘Glutamate Receptors – Kainate receptors’. •Kainate receptors (KARs) are abundantly expressed in the developing brain.•KARs modulate synaptic transmission, plasticity and network excitability.•KARs regulate development and maturation of neuronal circuits.•KAR dysfunction may contribute to neurodevelopmental disorders.
