Electrical Brain Stimulation
Electrical brain stimulation (EBS), also referred to as focal brain stimulation (FBS), is a form of electrotherapy and neurotherapy 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. EBS is used for research or for therapeutic purposes. History Electrical brain stimulation was first used in the first half of the 19th century by pioneering researchers such as Luigi Rolando (1773–1831) and Pierre Flourens (1794–1867), to study the brain localization of function, following the discovery by Italian physician Luigi Galvani (1737–1798) that nerves and muscles were electrically excitable. The stimulation of the surface of the cerebral cortex by using brain stimulation was used to investigate the motor cortex in animals by researchers such as Eduard Hitzig (1838–1907), Gustav Fritsch (1838–1927), David Ferrier (1842� ...

Luigi Galvani
Luigi Galvani ( , , ; ; 9 September 1737 – 4 December 1798) was an Italian physician, physicist, biologist and philosopher who studied animal electricity. In 1780, using a frog, he discovered that the muscles of dead frogs' legs twitched when struck by an electrical spark. This was an early study of bioelectricity, following experiments by John Walsh (scientist), John Walsh and Hugh Williamson. Early life Luigi Galvani was born to Domenico Galvani and Barbara Caterina Foschi, in Bologna, then part of the Papal States. The house in which he was born may still be seen on Via Marconi, 25, in the center of Bologna. Domenico was a goldsmith. His family had produced several illustrious men. Galvani then began taking an interest in the field of "medical electricity". This field emerged in the middle of the 18th century, following electrical researches and the discovery of the effects of electricity on the human body by scientists including Bertrand Bajon and Ramón María Termey ...

Stereotactic Method
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc. In theory, any organ system inside the body can be subjected to stereotactic surgery. However, difficulties in setting up a reliable frame of reference (such as bone landmarks, which bear a constant spatial relation to soft tissues) mean that its applications have been, traditionally and until recently, limited to brain surgery. Besides the brain, biopsy and surgery of the breast are done routinely to locate, sample (biopsy), and remove tissue. Plain X-ray images (radiographic mammography), computed tomography, and magnetic resonance imaging can be used to guide the procedure. Another accepted form of "stereotactic" is "stereotaxic". The word roots are '' stereo-'', a prefix derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Bartholow
Roberts Bartholow or Roobert Bartholow (November 28, 1831 – May 10, 1904) was an American physician and a professor at several American medical colleges. He is best known for his experiments involving a 30-year-old patient named Mary Rafferty. Rafferty was admitted to Good Samaritan Hospital in Cincinnati, Ohio in 1874 with a 2-inch-diameter (51 mm) hole in her skull caused by a cancerous ulcer. Bartholow experimented with applying current to Rafferty's exposed dura using needle electrodes. His report detailed the first observations of how electrical stimulation of the brain affects motor functions of the body, but many ethical concerns were raised about the way in which he carried out his experiments. Rafferty went into a coma for three days and then died the day after coming out of the coma from a massive seizure. Education and career Roberts Bartholow was born in New Windsor, Maryland. He attended Calvert College in his hometown, and graduated in 1848 with a Bachel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurologist
Neurology (from , "string, nerve" and the suffix -logia, "study of") is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system, using various techniques of neurotherapy. IEEE Brain (2019).

Neurosurgeon
Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the medical specialty that focuses on the surgical treatment or rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nervous system, and cerebrovascular system. Neurosurgery as a medical specialty also includes non-surgical management of some neurological conditions. Education and context In different countries, there are different requirements for an individual to legally practice neurosurgery, and there are varying methods through which they must be educated. In most countries, neurosurgeon training requires a minimum period of seven years after graduating from medical school. United Kingdom In the United Kingdom, students must gain entry into medical school. The MBBS qualification (Bachelor of Medicine, Bachelor of Surgery) takes four to six years depending on the student's route. The newly qualified physician must then comple ...

Gustav Fritsch
Gustav Theodor Fritsch (5 March 1838 – 12 June 1927) was a German anatomist, anthropologist, traveller and physiologist from Cottbus. Fritsch studied natural science and medicine in Berlin, Breslau and Heidelberg. In 1874 he became an associate professor of physiology at the University of Berlin, where he was later appointed head of the histology, histological department at the physiological institute. He is known for his work with neuropsychiatrist Eduard Hitzig (1839–1907) involving the localization of brain function, localization of the motor areas of cerebral cortex, motor areas of the brain. In 1870, the two scientists probed the cerebral cortex of a dog to discover that electrical stimulation of different areas of the cerebrum caused involuntary muscular contractions of specific parts of the dog's body. Along with his medical studies, Fritsch was also known for his ethnography, ethnographical research in southern Africa (1863–66), during which time he traveled fr ...

Motor Cortex
The motor cortex is the region of the cerebral cortex involved in the planning, motor control, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus. Components The motor cortex can be divided into three areas: 1. The primary motor cortex is the main contributor to generating neural impulses that pass down to the spinal cord and control the execution of movement. However, some of the other motor areas in the brain also play a role in this function. It is located on the anterior paracentral lobule on the medial surface. 2. The premotor cortex is responsible for some aspects of motor control, possibly including the preparation for movement, the sensory guidance of movement, the spatial guidance of reaching, or the direct control of some movements with an emphasis on control of proximal and trunk muscles of the body. Located anterior to the primary mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
