The retina is part of the brain and contains specialized cells that process visual information. This research studies unusual retinal cells that become silent when exposed to visual stimuli rather than becoming active. Experiments reveal multiple subtypes responding to different visual patterns, improving understanding of how the eye and brain process visual signals.

This research compares English and German preposition use, focusing on when prepositions can be dropped in short answers. Through speaker judgments of dialogue naturalness, it shows that flexibility is context-dependent rather than a simple English–German contrast, revealing subtle grammatical and structural influences.
