Belonging to the broader class of glutamatergic neurons, this neuron type is characterized by its output connections that stretch outside the telencephalon, a region encompassing the cerebrum in the brain. This classification is notable for the release of glutamate, an excitatory neurotransmitter, which plays a pivotal role in neural communication, memory formation, learning, and regulation of various neurodevelopmental and neuropathological processes. Functionally, the extratelencephalic-projecting glutamatergic cortical neurons are responsible for transmitting information from the cortex to targets located outside the telencephalon, such as the thalamus, brainstem, and spinal cord. Their ability to facilitate long-range communication allows for the integration of different functional domains across the central nervous system, thereby contributing to various sensory, motor, cognitive, and affective functions. By enabling the exchange of signals between different brain structures, these neurons play an important role in coordinating complex activities and behaviors. The neurotransmitter glutamate produced and released by these neurons heightens the excitability of the connected neurons, enabling messages to pass more readily through the network. Extratelencephalic-projecting glutamatergic cortical neurons are integrated into precise circuitry with specific synaptic targets. Essentially, they contribute to the orchestrated relay of information throughout the brain and the overall coordination of neural networks. Defects or dysfunctions within these cells have been implicated in a variety of neurodevelopmental disorders and pathological conditions, highlighting their critical role in maintaining healthy brain function.
