This paper presents the application of finite element method in analysis of the electromagnetic field within real head model exposed to a time varying magnetic field produced by the circuit-driving loop. To analyze the electromagnetic field under Transcranial Magnetic Stimulation precisely and display the stimulating effect of the loops in different geometrical forms, a 3-D real head model reconstructed...
Transcranial magnetic stimulation (TMS) is a new tool for the study of the human brain and for neurological therapeutics. Magnetic coil design is very important in the TMS technique. Precise spatial localization of stimulation sites is the key of efficient functional magnetic stimulations. This paper develops circular coils, figure-of-8 coils and coil array elements in order to realize a transcranial...
Magnetic fields simulating EEG rhythm were used to stimulate Wistar rats to explore the effect of magnetic field on retrieval (recall) ability and its mechanism. The results indicated that most of the weak magnetic fields (>10 minutes) simulating the EEG rhythm of human brain impaired the retrieval of long-term memory significantly (P<0.05), but weak magnetic field with special rhythm may even...
