Complex neuronal circuitries such as those present in the mammalian cerebral cortex have evolved as balanced networks of excitatory and inhibitory neurons. Although the establishment of appropriate numbers for these cells is essential for brain function and behaviour, our understanding of this fundamental process is very fragmentary. Here we show that interneuron cell survival in mice depends on the activity of pyramidal cells during a critical window of postnatal development, in which excitatory synaptic input to individual interneurons predicts their outcome. Pyramidal cells regulate interneuron survival through the negative modulation of PTEN signalling, which effectively drives interneuron cell death during this period. Taken together, our findings indicate that activity-dependent mechanisms dynamically adjust the number of inhibitory cells in nascent local cortical circuits, ultimately establishing the appropriate proportions of excitatory and inhibitory neurons in the cerebral cortex.
