  • Stimulation Recording in Frog Sciatic Nerve

    1321 Words  | 5 Pages

    Stimulation Recording in Frog Sciatic Nerve Methods: Dissection of the Gastrocnemius Muscle and the Sciatic Nerve In this experiment the frog sciatic nerve was used; the frogs were carefully handled and deeply anesthetized in order to be permanently unconscious. Pithing was used to destroy the brain pain center making the frog insensitive to pain. The gastrocnemius muscle was dissected and the sciatic nerve was carefully removed. The frog ringer solution was prepared. The ingredients used included

  • Does Deep Brain Stimulation Pose?

    2086 Words  | 9 Pages

    Does Deep Brain Stimulation Pose a Threat to Personal Identity? Introduction Deep brain stimulation (DBS) is a procedure where electrodes are surgically implanted in the brain to stimulate or inhibit electrical signals within it; the effects of DBS can be turned on and off and the level of stimulation can be adjusted. It has been shown to be effective in improving motor abilities and quality of life in those with Parkinson’s disease (Weaver, et al. 2009), and has been used for other psychiatric

  • Deep Brain Stimulation Implantation ( Shin ) Implantation

    919 Words  | 4 Pages

    Deep Brain Stimulation Implantation Deep brain stimulation (DBS) implantation is a procedure to insert a wire (lead) into one or both sides of the brain in order to deliver electrical currents to an area causing problems. The lead is attached to a power source that is implanted under the skin near the collarbone, chest, or abdomen. This procedure may be done to treat various medical conditions, such as Parkinson disease, essential tremor, and other neurological conditions that cannot be controlled

  • Summary of the Research: Treatment of Post-stroke Dysphagia with Repetitive Transcranial Magnetic Stimulation

    2580 Words  | 10 Pages

    In their study titled Treatment of post-stroke dysphagia with repetitive transcranial magnetic stimulation, Khedr, Abo-Elfetoh and Rothwell (2009) aimed to investigate the therapeutic potential of rTMS over the esophageal motor cortex for treating post-stroke dysphagia. The authors rationale for the purpose of this study is that dysphagia often follows a stroke. Due to the numerous and potential grave effects of dysphagia, developing best practices which ameliorate the condition has been long considered

    produced to allow the muscle to contract that many times and for the length of time. 2. The muscle will produce force for a longer period if the stimulator is briefly turned off than if the stimulations were allowed to continue without interruption. Explain why. Because for the brief time that the stimulation is off the muscle can produce more ATP to supply the contractions with. 3. Describe the difference between the current tracing and the myogram generated in step 6. The current tracing does

  • Taking a Look at Neurotransmitter Release

    724 Words  | 3 Pages

    Neurotransmitter release is a key step to neuro-transmission, in the middle of the 20th century; it has been clearly revealed that chemical signals transfer the great majority of the information in the brain. Therefore, different neurochemistry approaches have been emerged to investigate neurotransmitter release process. Later, introducing a radiolabeled precursor into the CNS and measuring the accumulation of a radiolabeled product have made critical improving and developing in vitro preparations

  • The Response Of The Sciatic Nerve

    1171 Words  | 5 Pages

    The study of the response of the sciatic nerve and the neuromuscular to the Rana pipens was constructed by the Comparative Animal Physiology lab manual for both the nerve compound action potential (Lab five) and the neuromuscular junction (Lab six) (Norris, et al.,2016). In order to analyze the responses of the sciatic nerve and the gastrocnemius of a Rana pipens, one exercise was selected from Lab five and five exercises were selected from Lab six. Both lab five and Lab six had a study length of

    At baseline, before stimulation, it was found that the more depressed an individual was, the less activation there was in the prefrontal lobes and caudate nucleus (Teneback et. al, 1999). Teneback et. al (1999) also noted that following high-frequency treatment, they noticed that the people who responded to the treatment had increased inferior frontal gyrus activity compared to those who did not respond to treatment and days later they also had decreased medial temporal activity. The prediction is
