Stimulation of deeper brain structures by transcranial magnetic stimulation (TMS) may be beneficial in the treatment of several neurological and psychiatric disorders. This paper presents numerical simulation of deep transcranial magnetic stimulation (dTMS) by considering double cone, H-and Halo coils. Three-dimensional distributions of the induced fields(More)
In this study, classical and molecular cytogenetic analyses were performed in tilapia fishes, Oreochromis mossambicus (XX/XY sex determination system), O. urolepis hornorum (WZ/ZZ sex determination system) and their hybrid by crossing O. mossambicus female × O. u. hornorum male. An identical karyotype ((2n = 44, NF (total number of chromosomal arms) = 50)(More)
OBJECTIVE To investigate the possibility for stimulating deeper brain regions while decreasing the electrical field in superficial cortical regions by employing coaxial circular coils. METHODS The Halo coil, Halo-circular assembly coil (HCA coil) and Halo coil working with two circular coils (HTC coil) were applied over a 36-tissue anatomically based head(More)
Health conditions in the Huainan Coal Mine have improved greatly since 1950. In particular, the work and living environments, the underground dust concentration, the water supply and waste disposal systems, and the nutritional value of miners' food have become much better. Thus the rates of occupational, infectious, and parasitic diseases and nutritional(More)
Stimulation of deeper brain structures by transcranial magnetic stimulation (TMS) plays a role in the study of reward and motivation mechanisms, which may be beneficial in the treatment of several neurological and psychiatric disorders. This paper presents numerical simulation of deep transcranial magnetic stimulation (dTMS) by considering double cone, H-,(More)
In this paper, we present a numerical simulation of transcranial magnetic stimulation in a real 3D child head model by employing a realistic figure-of-eight coil. The induced electric fields were calculated by impedance method and the results were compared with those obtained in an adult head model. It was found the electric fields present the maximum(More)
As important non-invasive techniques in brain stimulation, transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) have been studied and compared in this paper by employing impedance method and a 3D human head model. The quantitative analysis of distributions of current density and electric field by tDCS and TMS have been(More)
Stimulation of deeper brain structures by transcranial magnetic stimulation (TMS) plays a role in the study of reward and motivation mechanisms, which may be beneficial in the treatment of several neurological and psychiatric disorders. However, electric field distributions induced in the brain by deep transcranial magnetic stimulation (dTMS) are still(More)

Neuron is the basic unit of the biological neural system. The Hodgkin-Huxley (HH) model is one of the most realistic neuron models on the electrophysiological characteristic description of neuron. Hardware implementation of neuron could provide new research ideas to clinical treatment of spinal cord injury, bionics and artificial intelligence. Based on the(More)
