Path Integration and Cognitive Mapping Capacities in Down and Williams Syndromes

Frontiers in Psychology, 2020
Williams (WS) and Down (DS) syndromes are neurodevelopmental disorders with distinct genetic origins and different spatial memory profiles. In real-world spatial memory tasks, where spatial information derived from all sensory modalities is available ...

Avian magnetoreception: elaborate iron mineral containing dendrites in the upper beak seem to be a common feature of birds [PDF]

, 2010
The magnetic field sensors enabling birds to extract orientational information from the Earth’s magnetic field have remained enigmatic. Our previously published results from homing pigeons have made us suggest that the iron containing sensory dendrites ...

Automated detection and classification of beaked whale buzzes on bottom-mounted hydrophones

Frontiers in Remote Sensing, 2022
Beaked whales, like many other odontocetes, produce bouts of very rapid clicking that serve as a homing signal just prior to a prey capture attempt. For Blainville’s and Cuvier’s beaked whales (Mesoplodon densirostris, Md, and Ziphius cavirostris, Zc ...
