Evolution of neural circuits in the origin of behavioral novelty.
Article in Current opinion in behavioral sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The origin of phenotypic novelty is a central topic in evolutionary biology. In this review, I will discuss the neural circuit basis that underlies the emergence of behavioral novelties, emphasizing novel behaviors as evolutionary additions to existing behavioral repertoires and the circuit mechanisms crucial to their initial emergence, rather than their later refinement. I will describe two non-mutually exclusive mechanisms as possible common neural routes to behavioral novelty. First, existing motor modules can be redeployed for use in novel sensory-social contexts through transitions at circuit nodes linking decision-making and motor programs. Second, novel behavioral patterns can be encoded by the actualization of latent potentials in ancestral circuits. Together, these mechanisms suggest that nervous systems develop with remarkable potential to readily evolve new behaviors.
