DNA damage during early neurogenesis impairs interneuron migration without altering their ultimate cortical positioning
Proper interneuron migration and distribution are essential for optimal brain function. Disruptions of this process can impair the excitation/inhibition balance, leading to neurodevelopmental disorders. As such, ionizing radiation poses a particular risk to the developing brain, as it can lead to excessive fetal DNA damage and subsequent microcephaly. Although research on radiation-induced microcephaly has mainly focused on glutamatergic excitatory neurons, the impact on GABAergic interneurons is equally crucial. Understanding potential disruptions is essential for comprehensive insights into
