DNA fragments from Neandertals in the human genome shed light on brain evolution

Synesthesia is one of the most fascinating phenomena in psychology and the neurosciences. But only very slowly are its scientific mysteries being uncovered. Research in this field is gathering momentum, thanks to the studies being conducted by Simon Fisher from the Max Planck Institute for Psycholinguistics in the Dutch city of Nijmegen.

For us, it appears natural that children should start to speak at some point. Yet learning language is a major feat, which is still not fully understood even today. The Departments led by Caroline Rowland at the Max Planck Institute for Psycholinguistics in Nijmegen and Angela Friederici at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig are using a wide range of methods to investigate how children learn this complex system of communication with seemingly no effort.

Scientists from 100 countries work at the Max Planck Institutes. Here they write about their personal experiences and impressions. Julia Misersky, doctoral student at the Max Planck Institute for Psycholinguistics in Nijmegen, recently started her maternity leave. Here she introduces her research topic, explains how she plans to juggle her doctoral studies with motherhood, and talks about her commitment to improving conditions for young parents.

Our bodies, our behavior and even our brains are anything but symmetrical. And this seems to be an important factor in the seamless functioning of our thought, speech and motor faculties. Researchers at the Max Planck Institute for Psycholinguistics in Nijmegen are currently searching for genetic clues to this phenomenon. They want to decode the fundamental molecular biological mechanisms that contribute to asymmetry in the brain, and to identify possible causes for neurological disorders.

During everyday conversations, we often begin to speak before we have decided exactly what we want to say. Antje Meyer and her team at the Max Planck Institute for Psycholinguistics in Nijmegen are investigating how we plan sentences and what obstacles may stand in the way. To this end, the researchers test volunteers on a treadmill, construct virtual environments and travel to India to study whether illiterate individuals process language differently.

Human brain anatomy has undergone distinct changes during hominin evolution, accompanied by the emergence of complex cognitive functions. Despite recent advances in comparative genomics, we still have only limited insight into how genetic factors contributed to this reshaping of the brain. We addressed the question by using large-scale neuroimaging genomic data from present-day humans to reveal associations between various evolutionary annotations of the human genome and aspects of cortical anatomy and connectivity, spanning a range of periods over the last 30 million years. 

The ability of continuous prediction of words is considered the reason why we can follow quickly spoken language. But how does our brain manage to predict the content? And what are the costs and benefits of this approach? With our research on prediction, we want to pave the way to a better understanding of language comprehension.

When comprehending spoken language, we combine acoustic information with our learned linguistic knowledge. At the Max Planck Institute for Psycholinguistics, we have investigated in more detail what happens in the brain when we extract meaning from an acoustic signal: Brain signals “synchronize” with the signal in specific frequency bands. 

Even though we typically have little trouble having a spoken conversation with someone else, speech in everyday communication is a noisy and highly variable signal. The same word can be pronounced in very different ways. It is therefore quite remarkable that listeners have little trouble understanding speech with all its variation. The present study has revealed a neurobiological mechanism that helps listeners understand speech produced at different speech rates, involving brainwaves synchronizing to the rhythm of speech, in turn influencing how we perceive the words in the speech signal.

How does the human brain acquire a language? And why do some of us learn language earlier and faster than others?  In our research, we work to answer these questions by studying how children build a language system from the speech they hear in childhood. Our aim is to understand what drives language acquisition by discovering what differences exist in the brain’s learning mechanisms, how these differences arise, and why they affect the trajectory of learning so substantially.
