Virtual audiovisual everyday-life environments for hearing aid research
<p>The virtual audiovisual environments in this database are published in conjunction with the paper Hendrikse et al. (2019). These virtual audiovisual environments were designed based on a number of situations with high importance and/or occurrence in everyday-life of young and elderly normal-hearing and hearing-impaired persons. They were designed to have a big range of different target sources (one or multiple live speakers or loudspeakers, close or further away) and distractors (concurrent speakers or other sounds, close or further away, moving or stationary). Their purpose was to enable the measurement of realistic head-, eye- and torso-movement and EEG during listening tasks in everyday-life situations. A database of the measured movement behavior and EEG of 21 young normal-hearing and 19 elderly normal-hearing subjects is also available (see Related identifiers). The methods and an analysis of the subjective experience of these environments are published in Hendrikse et al. (2019). The environments include: a living room (watching the news on TV), a lecture hall (listening to a lecture), a cafeteria (listening to a 4-person conversation), a train station (listening to the announcements) and a street (listening to a 4-person conversation at a bus stop or waiting for someone at a cross-section). The environments contain speech material in German. 3D videos of the environments can also be found on Youtube: <a href="https://www.youtube.com/playlist?list=PL-v3EIoK6ZarlOvYqCu7LpDext3Iafwtr">https://www.youtube.com/playlist?list=PL-v3EIoK6ZarlOvYqCu7LpDext3Iafwtr</a></p>

Data from: Structured inhibitory activity dynamics in new virtual environments
<p>Inhibition plays a powerful role in regulating network excitation and plasticity; however, the activity of defined interneuron types during spatial exploration remain poorly understood. Using two-photon calcium imaging, we recorded hippocampal CA1 somatostatin- and parvalbumin-expressing interneurons as mice performed a goal-directed spatial navigation task in new visual virtual reality (VR) contexts. Activity in both interneuron classes was strongly suppressed but recovered as animals learned to adapt the previously learned task to the new spatial context. Surprisingly, although there was a range of activity suppression across the population, individual somatostatin-expressing interneurons showed consistent levels of activity modulation across exposure to multiple novel environments, suggesting context-independent, stable network roles during spatial exploration. This work reveals population-level temporally dynamic interneuron activity in new environments, within which each interneuron shows stable and consistent activity modulation.</p>
