New developments in the fields of biomagnetics and bioimaging have enabled the non-invasive brain-function measurement and localization of several human brain functions such as cognition, memory and learning. At the same time new biophysical phenomena such as cell and macromolecular alignment under strong magnetic fields and cancer therapies via magnetic nanoparticles and hyperthermia have opened new paths for biomedical engineering, cancer and immunological treatment. This paper presents a review on the recent work of our group in the topics of transcranial magnetic stimulation (TMS), magnetic resonance imaging (MRI), magnetoencephalography (MEG), cancer therapy and cell orientation.
