Intralaminar thalamic deep brain stimulation (ILN - DBS) has been shown to improve cognition and spatial memory acquisition.

However, while the maps for visual space and eye input were thought to originate from the segregation of thalamic afferents in visual cortex, the origin of the other maps remained unclear.

They found that altering the activity of three specific targets — GABAB currents, the potassium leak currents and hyperpolarization - activated thalamic currents — restored sleep patterns in their model.

Surprisingly, altering just the potassium leak currents or the hyperpolarization - activated thalamic currents could also restore normal deep sleep wave patterns.
