Ever wondered why your visual perception barely changes when you shut one eye? We found narrow-spiking neurons in the human LGN that strongly increased their response when their preferred eye was shut. We think these interneurons reduce responses of relay cells responding to the shut eye.

Effects of eye closure on the spiking activity of human lateral geniculate neurons - Nature Communications The LGN is a critical stage between the retina and visual cortex, but the properties of human LGN neurons are not fully understood. Here the authors report that they closely resemble those in monkeys ...

Our paper showing the first ever recordings of spiking activity from neurons in the human lateral geniculate nucleus has just been published in Nature Communications! Congrats to the whole team. #neuroskyence @nin-knaw.bsky.social @uofgpsychneuro.bsky.social

Thanks Andrew, and thanks for pointing out that interesting paper. Very likely a similar underlying mechanism - suppressive interactions are much weaker between stimuli that are perceived to belong to different surfaces.

New publication in Journal of Vision! 📢 doi.org/10.1167/jov.... Orientation-tuned surround suppression isn't 'hard-wired', but only works when the surround appears to be part of the same 3D surface. Great work Jessy Possel 💪. #neuroskyence @nin-knaw.bsky.social @uofgpsychneuro.bsky.social
