Significance: Fiber photometry (FP) is a widely used technique in modern behavioral neuroscience, employing genetically encoded fluorescent sensors to monitor neural activity and neurotransmitter release in awake-behaving animals. However, analyzing photometry data can be both laborious and time-consuming.
Aim: We propose the fiber photometry analysis (FiPhA) app, which is a general-purpose FP analysis application. The goal is to develop a pipeline suitable for a wide range of photometry approaches, including spectrally resolved, camera-based, and lock-in demodulation.
Approach: FiPhA was developed using the R Shiny framework and offers interactive visualization, quality control, and batch processing functionalities in a user-friendly interface.
Results: This application simplifies and streamlines the analysis process, thereby reducing labor and time requirements. It offers interactive visualizations, event-triggered average processing, powerful tools for filtering behavioral events, and quality control features.
Conclusions: FiPhA is a valuable tool for behavioral neuroscientists working with discrete, event-based FP data. It addresses the challenges associated with analyzing and investigating such data, offering a robust and user-friendly solution without the complexity of having to hand-design custom analysis pipelines. This application thus helps standardize an approach to FP analysis.

In the hippocampal formation, cholinergic modulation from the medial septum/diagonal band of Broca (MSDB) is known to correlate with the speed of an animal's movements at sub-second timescales and also supports spatial memory formation. Yet, the extent to which sub-second cholinergic dynamics, if at all, align with transient behavioral and cognitive states supporting the encoding of novel spatial information remains unknown. In this study, we used fiber photometry to record the temporal dynamics in the population activity of septo-hippocampal cholinergic neurons at sub-second resolution during a hippocampus-dependent object location memory task using ChAT-Cre mice of both sexes.

Reciprocity is considered one of the vital mechanisms that sustain the evolution of cooperative behavior. However, free-riding, where assistance is received but not reciprocated, poses a serious threat to reciprocity behavior, which relies on future payback. Previous theories proposed that third-party punishment plays a vital role in preventing free-riding behavior.

Background And Purpose: The pathological role of the bile acid receptor TGR5/GPBA in Alzheimer's disease (AD) is not fully understood. We investigated the pharmacological effects and mechanisms of TGR5 in AD model mice.
Experimental Approach: TGR5 expression was assessed in AD mice using immunofluorescence and immunoblotting.

Social hierarchies are central to the organizational structure of group-living species, shaping individual physiology, behavior, and social interactions. Dopaminergic (DA) systems, particularly within the ventral tegmental area (VTA) and dorsal raphe nucleus (DR), have been linked to motivation and competitive behaviors, yet their region-specific contributions to social dominance remain insufficiently defined. This study investigated the role of VTA and DR DA neurons in regulating social dominance in sexually naïve male C57BL/6J mice.

Aggressive behavior can be acquired through observation, providing adaptive advantages but also posing significant social risks. In humans, individuals repeatedly exposed to aggression are more likely to engage in violent behavior later in life. Yet, the environmental factors and neural mechanisms underlying observationally acquired aggression remain unclear.
