A recent study using fMRI data found that all human senses activate the same deep brain regions, specifically the midbrain reticular formation and central thalamus, when a person is sharply focused. This surprising discovery indicates a shared subcortical network for sensory attention, regardless of the type of sensory input received. This research advances our understanding of how the brain organizes consciousness and could potentially lead to new treatments for conditions impacting attention and awareness.
