Dogs are increasingly used as a model for neuroscience due to their ability to undergo functional MRI fully awake and unrestrained, after extensive behavioral training. Still, we know rather little about dogs’ basic functional neuroanatomy, including how basic perceptual and motor functions are localized in their brains. This is a major shortcoming...

The notion of a connection between autism and music is as old as the first reported cases of autism, and music has been used as a therapeutic tool for many decades. Music therapy holds promise as an intervention for individuals with autism, harnessing their strengths in music processing to enhance communication and expression. While previous random...

To promote collaboration across canine science, address replicability issues, and advance open science practices within animal cognition, we have launched the ManyDogs consortium, modeled on similar ManyX projects in other fields. We aimed to create a collaborative network that (a) uses large, diverse samples to investigate and replicate findings,...

Comparative neuroimaging allows for the identification of similarities and differences between species. It provides an important and promising avenue, to answer questions about the evolutionary origins of the brain´s organization, in terms of both structure and function. Dog functional magnetic resonance imaging (fMRI) has recently become one parti...

Many autistic children suffer from social communication problems, reduced participation, and mental health issues. Music therapy has beneficial but heterogeneous effects; its mechanisms are incompletely understood. The Music for Autism (M4A) trial aims to replicate and expand a previous trial examining brain mechanisms and clinical outcomes of musi...

Finding ways to investigate false belief understanding nonverbally is not just important for research in preverbal children, but it is the only way to assess theory of mind-like (ToM) abilities in nonhuman animals. In this preregistered study, we adapted the design from a previous study on dogs (Lonardo et al., 2021) to investigate false belief und...

Although dogs have a special place in human history as the first domesticated species and play important roles in many cultures around the world, their role in scientific studies has been relatively recent. With a few notable exceptions (e.g., Darwin, Pavlov, Scott & Fuller), domestic dogs were not commonly the subject of rigorous scientific invest...

It provides an important and promising avenue, to answer questions about the evolutionary origins of the brain’s organization, in terms of both structure and function. Dog fMRI has recently become one particularly promising and increasingly used...

Retrieval practice improves retention of information in long-term memory more than restudy, but the underlying neural mechanisms of this “Retrieval Practice Effect” (RPE) remain little understood. Therefore, we investigated the behavioral and neural differences between previously retrieved versus re-studied items at final retrieval. Thirty younger...

Retrieving information improves subsequent memory performance more strongly than restudying. However, despite recent evidence for this retrieval practice effect (RPE), the temporal dynamics, age-related changes, and their possible interactions remain unclear. Therefore, we tested 45 young (18–30 years) and 41 older (50 + years) participants with a...

The retrieval (or testing) of information leads to better memory performance compared with reencoding. This phenomenon is known as “testing effect” or “retrieval practice effect” and has been primarily described in behavioral studies with healthy young subjects. However, possible age-related changes and their associated underlying neural processes,...

We present a publicly available dataset of 228 healthy participants comprising a young (N=154, 25.1±3.1 years, range 20–35 years, 45 female) and an elderly group (N=74, 67.6±4.7 years, range 59–77 years, 37 female) acquired cross-sectionally in Leipzig, Germany, between 2013 and 2015 to study mind-body-emotion interactions. During a two-day assessm...

We present a publicly available dataset of 227 healthy participants comprising a young (N=153, 25.1±3.1 years, range 20–35 years, 45 female) and an elderly group (N=74, 67.6±4.7 years, range 59–77 years, 37 female) acquired cross-sectionally in Leipzig, Germany, between 2013 and 2015 to study mind-body-emotion interactions.
