Topic: refuge tracking

This study investigates multisensory integration in weakly electric fishes, Apteronotus albifrons and Eigenmannia virescens, during their natural refuge tracking behavior. Our goal is to examine and model the sensory reweighting that occurs in the midbrain in relation to changes in the sensory salience. Specifically, we manipulate illumination (light, dim light, dark), conductivity (low, medium, high), refuge structure (with/out windows), and refuge length (short, medium, high) and observe how the weights of visual and electrosensory systems are dynamically adjusted. We conducted a total of 27

Animals improve their perception of the world by constantly integrating multi-modal sensory information they gather from the environment. The CNS weights and combines this information based on their reliabilities. However, cue reliability depends greatly on its salience, and it varies continuously while the animal moves through different environments. Our goal is to investigate the mechanisms adopted by animals while they regulate their behavior during multisensory behavioral control. Specifically, we study multisensory integration in Eigenmannia virescens, a species of weakly electric fish du

Active sensing is a process using which animals improve their environmental perception and exploration at the cost of extra energy. Despite the ubiquitous nature of this phenomenon across animal taxa, the mechanisms initiating active sensing movements remain unknown. Existing models in the literature model active sensing either as an open-loop noise source or a stochastic resonance generator. In contrast, our previous work (Karagoz et al., 2024) model active sensing as a closed-loop process, where animals seek to improve its state-estimation performance by conducting additional active sensing
