Theta/gamma Co-modulation Disruption After NMDAr Blockade by MK-801 Is Associated with Spatial Working Memory Deficits in Mice.
Article in Neuroscience, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Abnormal N-methyl-D-aspartate receptor (NMDAr) function has been linked to oscillopathies, psychosis, and cognitive dysfunction in schizophrenia (SCZ). Here, we investigate the role of NMDAr hypofunction in pathological oscillations and behavior. We implanted mice with tetrodes in the dorsal/intermediate hippocampus and medial prefrontal cortex (mPFC), administered the NMDAr antagonist MK-801, and recorded oscillations during spontaneous exploration in an open field and in the y-maze spatial working memory test. Our results show that NMDAr blockade disrupted the correlation between oscillations and speed of movement, crucial for internal representations of distance. In the hippocampus, MK-801 increased gamma oscillations and disrupted theta/gamma coupling during spatial working memory. In the mPFC, MK-801 increased the power of theta and gamma, generated high-frequency oscillations (HFO 155-185 Hz), and disrupted theta/gamma coupling. Moreover, the performance of mice in the spatial working memory version of the y-maze was strongly correlated with CA1-PFC theta/gamma co-modulation. Thus, theta/gamma mediated by NMDAr function might explain several of SCZ's cognitive symptoms and might be crucial to explaining hippocampal-PFC interaction.
