Neuromodulation

Neuromodulation (pronounced: noor-oh-moh-dyoo-lay-shuhn) is a technology that acts directly upon nerves. It is the alteration—or modulation—of nerve activity by delivering electrical or pharmaceutical agents directly to a target area.

Etymology

The term "neuromodulation" is derived from the Greek words "neuron" meaning nerve and "modulation" meaning the act of regulating something.

Definition

Neuromodulation is a process that regulates nervous activity through the delivery of electrical stimuli or chemical agents to specific neurological sites in the body. It is used to normalize – or modulate – nerve function.

Types of Neuromodulation

There are several types of neuromodulation, including:

  • Spinal Cord Stimulation: This involves the delivery of electrical signals to the spinal cord to control chronic pain.
  • Deep Brain Stimulation: This involves the delivery of electrical signals to specific areas of the brain to treat movement disorders such as Parkinson's disease.
  • Vagus Nerve Stimulation: This involves the delivery of electrical signals to the vagus nerve to treat epilepsy and depression.
  • Transcranial Magnetic Stimulation: This involves the delivery of magnetic pulses to the brain to treat depression and other disorders.

Applications

Neuromodulation is used in the treatment of various medical conditions, including:

  • Chronic Pain: Neuromodulation can help manage chronic pain by altering pain signals.
  • Parkinson's Disease: Deep brain stimulation, a form of neuromodulation, is often used to treat Parkinson's disease.
  • Epilepsy: Vagus nerve stimulation can help control seizures in people with epilepsy.
  • Depression: Both vagus nerve stimulation and transcranial magnetic stimulation are used to treat depression.

Related Terms

  • Neurostimulation: This is a subset of neuromodulation that uses electrical signals to stimulate nerves.
  • Neurotransmitter: This is a chemical substance that transmits nerve impulses across a synapse.
  • Neuroplasticity: This is the ability of the brain to form and reorganize synaptic connections, especially in response to learning or experience or following injury.
