Project description
The brain behind alarm calls in birds
‘Watch out, and take cover!’ These urgent warnings are essential for survival, both in humans and animals. Yet, alarm calls present an evolutionary puzzle: they signal danger but can also endanger the caller. While the benefits of alarm calls are clear, the brain’s role in producing and responding to these signals remains largely unexplored. The ERC-funded NeurAlarm project aims to bridge this gap by investigating the neural basis of alarm calling. Using advanced wireless technology, researchers will monitor brain activity in wild songbirds as they engage in alarm calling in their natural habitats. NeurAlarm will shed light on how these neural circuits collaborate to manage responses to threats, offering deeper insights into decision-making in high-stress situations.
Objective
“Watch out!” - is the term we use to inform somebody about a potentially dangerous situation. “Take cover!” - we shout when the threat is imminent. Not only humans but also animals use alarm calls to warn conspecifics about danger, and the value of these signals for increasing the chance of survival in the receiver is without controversary. But, alarm calls often harm the sender through their production and are therefore considered an evolutionary paradox, which has fascinated scientists for many decades. While the function, development and evolution of alarm calls have extensively been studied, the proximate mechanisms relating to how the brain controls alarm call production or the reactions to alarm calls are unknown. Uncovering the brain’s role in antipredator behaviour, such as alarm calling, is fundamentally important for understanding how neural systems facilitate decision-making in life-threatening situations.
My project will be first in studying the neural basis of alarm calling behaviour and will exploit a unique and completely natural approach. Brain activity at the cellular level will be wirelessly recorded in parallel to individual vocal activity in groups of free-ranging, wild songbirds while they emit, listen and react to alarm calls in their natural habitat. In 2017, we pioneered the application of extracellular neurophysiology during field research, and are currently the only researchers worldwide who conduct neurophysiological experiments with wild animals outside a laboratory. Brain regions belonging to three different neural circuits will be targeted within my project: the vocal control system, the hearing system and the fear system. The new knowledge produced by my project will help us to understand the computations the brain has to perform when we warn others about danger or when we get warned, and will elucidate how different neural circuits naturally work together to flexibly adjust fear reactions to the threat level signalled by alarm calls.
