When a visual stimulus enters the eye, how does the brain transform it into the subjective experience of “I see”? Traditional theories posited the cerebral cortex as the epicenter of conscious perception, relegating the thalamus to a mere relay station for sensory signals. However, a groundbreaking study recently published in Science has overturned this paradigm, identifying the mediodorsal thalamic nuclei (MDm) and intralaminar nuclei (ILN) as the true “gatekeepers” of conscious perception.<span><sup>1</sup></span> Through dynamic connectivity with the prefrontal cortex, these nuclei determine which sensory information gains access to the conscious perception.

Conscious perception involves the awareness and understanding of one's environment, internal stimuli, and cognitive processes.
