Strength of activation and temporal dynamics of bioluminescent-optogenetics in response to systemic injections of the luciferin.

BioLuminescent OptoGenetics ("BL-OG") is a chemogenetic method that can evoke optogenetic reactions in the brain non-invasively. In BL-OG, an enzyme that catalyzes a light producing reaction (i.e.

A Flicker Change Detection Task Reveals Object-in-Scene Memory Across Species.

Tests of recognition memory in macaques typically assay memory for objects or isolated images, over time spans of seconds to hours from stimulus presentation, and/or require extensive training. Here, we propose a new application of the flicker change detection task that could measure object-in-scene memory days after single-trial exposures. In three experiments, participants searched for a changing object - or "target" - embedded within a scene as their eye movements were tracked.
