What are Neurosprosthetics?


Neuroprosthetics (also called Neural Prosthetics) is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses, artificial implantable devices to replace or improve the function of an impaired nervous system.Neuroprosthetics are the set of physical devices that interact with the brain or other neural tissue to augment, restore, or otherwise impact function.
Neuroprosthetics are electrical stimulation technologies that replace or assist damaged or malfunctioning neuromuscular organ systems and attempt to restore normal body processes, create or improve function, and/or reduce pain. These systems are either implanted or worn externally on the body. Such assistive devices range from intramuscular stimulation systems designed to limit limb atrophy in paralysis, to implanted bladder voiding systems and more complex implanted neuromuscular control.
The process of transitioning this technology into a clinically useful device will require two parallel paths of research. In the first path, experimental paradigms involving microelectrode array recordings in behaving animals will be developed in conjunction with signal processing techniques for studying the unknown aspects of neural coding and functional neurophysiology. These signal processing techniques will then be implemented in portable, low-power, wireless hardware.The second path, high-density array ECoG recordings in humans, provides a less invasive technique for neural interfaces however it still remains unknown how to extract BMI control signatures that are sufficiently spatially and temporally resolved. Neuroprosthetics is an area of intense scientific and clinical interest and rapid progress. The word’ prosthesis’ is derived from the Greek word for ‘addition’. A breakdown of the word includes ‘pros’ meaning ‘to’, and ‘thesis’, meaning ‘a placing’. Neuroprosthetic are in their infancy just now, but they offer two things that are truly wonderful:
1. Bypassing the body, and letting the mind interface directly with VR, for the ultimate immersive experience – the virtual body becomes as the normal functioning body
2. Augmented body parts will be able to be fitted to the body, and controlled by the brain as if you were born with them – after a little training, without conscious thought.

Biomedical innovation:Memories Controlled by a switch in Rat

A method to turn memories on and off with the flip of a switch, has been developed by the scientists.

Using an electronic system that duplicates the neural signals associated with memory, they managed to replicate the brain function in rats associated with long-term learned behaviour, even when the rats had been drugged to forget.

“Flip the switch on, and the rats remember. Flip it off, and the rats forget,” said Theodore Berger of the USC Viterbi School of Engineering‘s department of biomedical engineering.
