  2. Electroconvulsive therapy - Wikipedia

    en.wikipedia.org/wiki/Electroconvulsive_therapy

    Patients who received pulsing electrical impulses, as opposed to a steady flow, seemed to incur less memory loss. The vast majority of modern treatment uses brief pulse currents. [70] A greater number of treatments and higher electrical charges (stimulus charges) have also been associated with a greater risk of memory impairment. [35]

  3. Electrical brain stimulation - Wikipedia

    en.wikipedia.org/wiki/Electrical_brain_stimulation

    Electrical brain stimulation (EBS), also referred to as focal brain stimulation (FBS), is a form of electrotherapy used as a technique in research and clinical neurobiology to stimulate a neuron or neural network in the brain through the direct or indirect excitation of its cell membrane by using an electric current.

  4. Electrical injury - Wikipedia

    en.wikipedia.org/wiki/Electrical_injury

    Current: The higher the current, the more likely it is lethal. Since current is proportional to voltage when resistance is fixed , high voltage is an indirect risk for producing higher currents. Duration: The longer the shock duration, the more likely it is lethal—safety switches may limit time of current flow.

  5. Transcranial direct-current stimulation - Wikipedia

    en.wikipedia.org/wiki/Transcranial_direct...

    The vertical axis represents the current intensity in milliamp (mA), while the horizontal axis illustrates the time-course. In transcranial magnetic stimulation (TMS), an electric coil is held above the region of interest on the scalp that uses rapidly changing magnetic fields to induce small electrical currents in the brain. There are two ...

  6. Cortical stimulation mapping - Wikipedia

    en.wikipedia.org/wiki/Cortical_stimulation_mapping

    This lesion can prevent or produce a testable response, such as the movement of a limb or the ability to identify an object. The electric current from the electrode stimulates whatever function that site in the brain is responsible for, in essence telling the surgeon or examiner what a specific locale in the brain does. [6]

  7. Threshold potential - Wikipedia

    en.wikipedia.org/wiki/Threshold_potential

    The current spreads quicker in a cell with less resistance, and is more likely to reach the threshold at other portions of the neuron. [ 3 ] The threshold potential has also been shown experimentally to adapt to slow changes in input characteristics by regulating sodium channel density as well as inactivating these sodium channels overall.

  8. Transcranial magnetic stimulation - Wikipedia

    en.wikipedia.org/wiki/Transcranial_magnetic...

    Transcranial magnetic stimulation (TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to induce an electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a magnetic coil connected to the scalp. The stimulator ...

  9. Excitatory postsynaptic potential - Wikipedia

    en.wikipedia.org/wiki/Excitatory_postsynaptic...

    In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential. This temporary depolarization of postsynaptic membrane potential , caused by the flow of positively charged ions into the postsynaptic cell, is a result of opening ligand-gated ion ...
