Electrical Activities in the Human Body

The players of a high school football team were traveling home from their football game in Fernandina Beach, Florida. It had been a tough night. It was August and still hot. The game had lasted three hours, and the players had to play offense, defense, and special teams because there

Evoked potential tests- This test record electrical signals produced by nervous system in response to stimuli. An evoked potential test may use visual stimuli or electrical stimuli. Electrodes measure how quickly the information travels down your nerve pathways.

The EEG results are used to determine where sensors will be attached, to earlobes, or even hair to transmit thoughts through a transducer. The patient then must complete "tasks" by thought utilizing the appropriate brainwaves depending on the individual goal or disorder of that subject.

Cerebral palsy people usually very stiff and unusual relaxed and ‘’floppy ‘’ limbs which may also held in an unusual or awkward position

The brain is one of the most complex organ in our bodies. To learn about the brain scientists use electrical stimulation. Electrical stimulation is the use of electrical probes to determine functions of the brain. Clinical observation of patients have also helped scientists learn more about the brain. Case studies of different patients such as Phineas Gage have helped to learn about the different functions of the brain and how they work together to perform complex activities.

There are different kinds of joints in the human body (hinge/ball joint and socket and spin for example). They are joined together ball joints and socket joints fit together nicely do you can move your ankles, toes and fingers. These are all surrounded by ligaments and tendons which you can cause damage o by moving them incorrectly. such as not moving a person up the bed correctly such as putting your arms under their armpit, and dragging them u the bed. Lifting a person off the floor without a hoist but instead lifting them under their arms, this could cause their joint to dislocate or new hip joint ruined by incorrect handling, or muscles, tendons to be hurt. There are 3 different layers to the skin the epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.

There have been solutions that were introduced in the past and that are still used today to determine if a person has epilepsy. One of the solutions is called the electroencephalography (EEG), which was introduced in 1929 by the German psychiatrist Hans Berger (Jefferys, 2010). This was a breakthrough in psychiatric and neurological history. It was a minimally invasive diagnostic test that recorded the electrical patterns in a person’s brain. This allowed doctors to measure the electricity that the brain makes and to determine the brain’s activity. Overtime, it became popularly used during the late 1940s and early 1990s (Jefferys, 2010). This was the time when digital EEG recordings became available. Then, in the late 1990s, the digital recordings became faster, demonstrating the presence of ripples and fast ripples, which marked as epileptogenic zone (Jefferys, 2010). During an EEG, a patient would have tiny electrodes and wires attached to his/her head. The brain waves would be detected through the electrodes, which would then allow for the EEG machine to formulate the brain signals and record them on a paper or on a screen (“EEG,” 2016). An EEG is still used today. Another solution used to determine if a person has epilepsy is the patch-clamp technique. It was developed by Neher and Sakmann between the 1970s and 1980s. This method

We denied the medical services listed above because after a review of the clinical information provided by Dr. Carol DeCosta, the Medical Director has determined that Electromyography (A diagnostic test that records the electrical activity of muscles) and Nerve conduction studies (Measure conduction in response to an electrical stimulus) are not medically necessary.

These are common |-EKG monitoring- to monitor the electrical activity of the heart and dysrhythmias. |

The oscilloscope was used to determine that electrode placement was sufficient to record neural activity. This was determined by looking for a recording with minimal background noise and clear spontaneous extracellular action potentials (EAPs) . Criteria for an EAP included the presence of a clear bi- or triphasic waveform amplitude peak above 10 mV.

According to World Health Organisation (2017), around 50 million people worldwide have epilepsy. Unfortunately, epilepsy cannot be cured, but could be controlled by pharmacological or electrical treatment based on seizure prediction (Moghim & Corne, 2014). Since EEG has advantages such as speed, high time resolution and non-invasive natures, it maintains one of the most frequently used tools in predicting epilepsy (Hasan et al. 2017).

The Muscular and Nervous Systems of our body are two of eight major body functional systems that help us maintain homeostasis or in a chemical balance within our bodies. When the body cannot maintain homeostasis there is usually some sort of sickness or disease that is targeting one of our major body functions. An example of two diseases that could affect our homeostasis within our Muscular and Nervous System are Hydrocephalus and Dystonia.

An Electroencephalogram ( EEG) is a test that has the ability to detect abnormal brain activity. During an EEG a patients head is fitted with small metal disk that are then connected to small thin wires called electrodes(Wilson,2013). These electrodes recorded electrical activity in the brain. Normal brain activity gives off a consistent pattern of waves, where abnormal brain activity cause spikes to be shown in the patterns. Most EEG's preformed, are done sleep deprived. An EEG can effectively track stages of sleep, helping diagnosis sleep disorders. Tracking abnormal brain waves is also used to help diagnosis seizure disorders, certain types of seizures such as absence seizures do not always present with physical symptoms such as convulsions,

The neurons in the brain tissue communicate with each other via electrical signals, generating measurable action potential activity. Electrophysiological techniques have been developed to measure this electrical activity. Electrophysiological techniques are some of the classic methods of brain research, partly because they are very sensitive and accurate. They provide quite a number of insights into the subject’s mind as well as allow for study of how the brain works. They can be used during brain surgery as well as when the patient is awake and conscious, as the brain itself does not sense pain during the measurements. Although electrophysiology has been around for close to half a century, it has attained appreciable advances only in the last two decades. These advances have revolutionized the study of brain structure and functions, allowing neurophysiologists to monitor the brain’s activities directly during experiments (Sutler et al., 1999). Even with its significant impact in neurology, however, its presence has been so commonplace that many people no longer realize its ubiquity. This essay explores three electrophysiological techniques namely patch clamp, sharp electrodes, and brain slice recording. It describes how each of these techniques works as well as how advances in the techniques have
