tDCS
About tDCS Transcranial Direct Current Stimulation (tDCS) is a noninvasive brain stimulation technique that utilizes low amplitude direct currents applied via scalp electrodes to inject currents in the brain and thus modulates the level of excitability. DC stimulation has been used in various forms since the inception of modern electrophysiology at the beginning of nineteenth century. There has...

Transcranial magnetic stimulation or TMS is a neurophysiological technique that allows the induction of a current in the brain using a magnetic field to pass the scalp and the skull safely and painlessly. In TMS, a current passes through a coil of copper wire that is encased in plastic and held over the subject’s head. This coil resembles a paddle or a large spoon and is held in place either by...

Alvaro Pascual-Leone. Catedratico de Neurologia en Harvard he treatment is called “transcranial magnetic stimulation” and essentially involves placing a powerful electromagnet on a person’s scalp. The electromagnet alters brain activity by inducing an electromagnetic current in the underlying cortical neurons. Researchers aren’t sure why that would have a therapeutic...

This is an interesting question on a broader scale and is actually a critical point in a current online symposium [Virtual Symposium On Visual Culture and Bioscience].

electro-sensitivity in sharks
The hammer head shark has to be the best looking of the sharks – I have only seen them on the “Blue planet” series – I was intrigued at the massive shoals where they seem to perform this odd twitch where the body flexes almost like a spasm – i was wandering if this has anything to do with generating a pulse of electricity that other sharks can detect? as thses sharks are not electrically active –...

Mobile phones generate non-ionizing radiofrequency electromagnetic radiation generally at either 900MHz or 1.8GHz. However, in addition to the RF signal, there are lower frequency pulsed components associated with Time Division Multiple Access (TMDA) at 217Hz and 8.34Hz and a 2Hz Discontinuous Transmission (DTX) component produced when the user is connected but not speaking [3]. These low...

Magnetotactic bacteria
La primera indicación de que algunas bacterias eran sensibles al campo geomagnético la tuvo en 1975 Dick Blakemore, estudiante de doctorado entonces del Departamento de Microbiología de la Universidad de Massachusetts, en Amherst. Se han encontrado en marismas y agua salobres, pantanos y ciénagas, estanques de oxidación de aguas residuales, y en aguas termales. Además, pueden vivir como células...
