How much do you know about neurotechnology? Do you know what components are involved in the process of neurotechnology? The following article will cover many aspects of these components, including their major functions and how they relate to neurotechnology in general. Read on to learn more!

 


Technical Components used in Neuromodulation

Neuromodulation is used for many things, including diabetes treatment, depression, pain relief. The devices that are used for these applications include: Medical stimulators such as deep brain stimulators (DBS), vagus nerve stimulators (VNS), spinal cord stimulators (SCS), gastric electrical stimulation devices (GES) and other neuromodulatory systems used in medicine. These technical components work as a device to deliver electrical impulses or doses of neurotransmitters by way of intracranial electrodes implanted through surgical procedures at precise locations within the nervous system. The implants will be in charge of activating neurons of interest based on pre-programmed parameters.

 

Next Generation Technologies in Neuromodulation

Neurotechnology plays a key role in fields such as neuromodulation, prosthetics, and neuroscience. The devices that accompany these areas of study constitute what is referred to as neurotechnology or neutroelectronics. Neuromodulation therapies, for example, introduce mild electrical signals (referred to as excitatory currents) into neural tissue with hopes of altering neural processing. This is accomplished by placing electrodes on various regions of the body, including brain regions, where specific effects can be elicited. These technologies have been used for decades but have become increasingly more advanced and precise over time. Next generation technologies in neuromodulation include an array of devices including deep brain stimulators (DBS), spinal cord stimulators (SCS), cochlear implants, retinal implants, functional electrical stimulation systems (FES), peripheral nerve stimulators (PNS), vagus nerve stimulators (VNS), etc. These technologies are often considered part of a larger class called implantable medical devices which includes all types of biomedical equipment that can be implanted into patients or animals.

 

Benefits of Neurotechnology

The use of technical components enables one to acquire much more detailed information about nervous system functions in humans and animals than can be gained with methods of electrical or chemical stimulation. Electromagnetic recordings from single neurons have now become possible, even in man, opening up new possibilities for research on normal and pathological function of individual neurons. Over recent years a large variety of technical components have been developed that make it possible to study simultaneously a large number of different activity patterns in groups of nerve cells (for example, gamma rhythms). Computers make it possible to record continuously various parameters (voltage, current) from hundreds or thousands of sites for long periods without appreciable losses due to muscle artifacts.
