Responsive neurostimulation device

Responsive neurostimulation device is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Responsive neurostimulation device rather than just read about it. In short: Responsive neurostimulation device is a medical device that senses changes in a person's body and uses neurostimulation to respond in the treatment of disease. The FDA has approved devices for use in the United States in the treatment of epileptic seizures and chronic pain conditions.

Reference excerpt

Responsive neurostimulation device is a medical device that senses changes in a person's body and uses neurostimulation to respond in the treatment of disease. The FDA has approved devices for use in the United States in the treatment of epileptic seizures and chronic pain conditions. Devices are being studied for use in the treatment of essential tremor, Parkinson's disease, Tourette's syndrome, depression, obesity, and post-traumatic stress disorder.

Medical uses

Epilepsy The use of neurostimulation to treat epileptic seizures is only recommended in those who have failed multiple medications for the treatment of their seizures. The NeuroPace RNS system was approved for use by the FDA in 2013 and is the only medical device for epilepsy that uses responsive neurostimulation. The device is surgically implanted into the patient's head with electrical leads placed near the site in the brain that is believed to be the origin of the patient's seizures. These leads record electrical activity in the brain and deliver electrical stimulation when a seizure is detected. The device keeps a record of abnormal electrical activity that is reviewed by a neurologist to improve the detection and treatment of seizures. The patient is able to record when they are having symptoms with the device to see if their symptoms are correlating with seizures. The use of responsive stimulation has found to be effective for seizure reduction. Some patients are able to achieve complete seizure freedom with responsive and non-responsive neurostimulation.

Chronic pain

Neurostimulation for chronic pain is primarily through the use of spinal cord stimulators. These devices deliver electrical stimulation to different areas of the spine based on where they are implanted. Since 2012, Medtronic has produced spinal cord stimulators with accelerometers that can predict the patient's position. The device can be programmed to give additional electrical stimulation if the patient is thought to be in a more painful position.

Research Reponsive neurostimulation is an active area of research with multiple clinical trials underway. Continuous, or non-responsive, neurostimulation has been FDA approved since 2002 with the introduction of deep brain stimulators for Parkinson's disease. As medical technology has improved, so has our understanding of neural networks and their role in human disease. Adding sensing capabilities to these devices has provided new targets to stimulate and feedback into how to more effectively stimulate the brain. At this time, there are clinical trials for reponsive neurostimulation devices in the treatment of essential tremor, Parkinson's disease, Tourette's syndrome, depression, obesity, and post-traumatic stress disorder.

Worked examples

Example 1 — a first encounter with Responsive neurostimulation device

Start with the simplest possible case. Write down what Responsive neurostimulation device claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Responsive neurostimulation device before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Responsive neurostimulation device ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Responsive neurostimulation device

In research: Responsive neurostimulation device appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Responsive neurostimulation device in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Responsive neurostimulation device is common in secondary-school and first-year university syllabi. It links to neighbouring topics Epilepsy, Implants (medicine), Neuroprosthetics, so understanding it makes those chapters shorter.
In everyday life: Look for Responsive neurostimulation device outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
