Navigated and Robotized Transcranial Magnetic Stimulation based on 3D Laser Scans [PDF]

, 2011
Navigated and robotized Transcranial Magnetic Stimulation (TMS) is advancing forward in research and treatment. MRI-scans or other medical image data are typically used as navigation source. Unfortunately, scanning time is always short and expensive. For many TMSapplications the underlying brain topology is not necessarily needed.

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Night-migratory songbirds possess a magnetic compass in both eyes [PDF]

, 2012
Previous studies on European robins, Erithacus rubecula, and Australian silvereyes, Zosterops lateralis, had suggested that magnetic compass information is being processed only in the right eye and left brain hemisphere of migratory birds.
