They constitute approximately 20-30% of all cortical neurons and are characterized by their crucial role in inhibiting the activity of other neurons in the brain, adding a critical dimension of control to neural activity and information processing. These cortical interneurons are significantly implicated in maintaining the balance of excitation and inhibition in the cerebral cortex, which is essential for normal brain function. This balance allows the brain to respond appropriately to stimuli, modifying behavior and facilitating motor, sensory, and cognitive processes. Furthermore, cortical interneurons are instrumental in the generation of brain oscillations, rhythmic patterns of neuronal activity believed to contribute to various aspects of cognitive processes, such as attention, memory, and consciousness. Their unique function and morphology, along with the numerous subtypes distinguished by differences in physiological properties, molecular expression profiles, and connectivity patterns, highlight the complexity and diversity of cortical interneurons. Dysfunction or abnormal development of these cells has been linked to various neurological disorders, including epilepsy, schizophrenia, and autism.
