To achieve a comprehensive understanding of magnetoreception and vertebrate navigation, it is important to identify the brain regions and neuroanatomical pathways that are involved in processing the magnetic sensory information arriving in the brain from the peripheral nervous system. This project aims to reveal the entire neuronal circuitry underlying trigeminally mediated magnetoreception from distal terminations in the beak until magnetic information reaches the telencephalon (for multisensory integration). We will use a combination of neuronal tracing techniques and the detection of magnetic field-triggered expression of immediate early genes reflecting neuronal activation. To unequivocally show the biological relevance of each of the trigeminal components, we will combine microsurgical approaches with behavioural orientation experiments.

为了实现磁感受和脊椎动物导航的全面理解，重要的是要确定参与处理从外周神经系统到达大脑的磁感觉信息的大脑区域和神经解剖通路。该项目旨在揭示三叉神经介导的磁感受的整个神经回路，从喙的远端终端，直到磁信息到达端脑（多感觉整合）。我们将结合使用神经元示踪技术和磁场触发的反映神经元激活的即刻早期基因表达的检测。为了明确显示每个三叉神经成分的生物相关性，我们将联合收割机显微手术方法与行为定向实验相结合。
