Biomedical Engineers from Hyderabad ace at BioAsia Healthcare 2015

SharathChandra C, B H V Mani Kanta Swamy, G VijayaBhaskar B.Tech III year students of Biomedical Engineering, B. V. Raju Institute of Technology, Narsapur won First Prize in BioAsia 2015 Healthcare Devthon. The team was given Rs. 1 lakh grant for further development of the product and the team will be working with Technology Business Incubation Center, BITS Pilani (Hyderabad Campus).

BioAsia  2015 was an initiative to spur innovations in healthcare & life sciences through co-creation. Healthcare Devthon brought together healthcare experts, doctors, designers, engineers, technologists and developers together onto one platform to discover, design and rapidly prototype technologies and solutions relevant to the life sciences and healthcare fields. The goal is to facilitate the development of products and services that address unmet needs and are positioned to be rapidly adopted by end-users.

Brain Machine Interface Muscle control bypassing Spinal Cord


paralysed monkey bypass spinal cord brain machine Bypassing Spinal Cord, New Brain Computer Interface Sends Signals Directly from Brain to Muscles

 

Medical researchers have successfully enabled a paralyzed monkey to move its hand, by delivering messages from the brain directly to the muscles, completely bypassing the spinal cord. This is a breakthrough for spinal-cord injuries, it opens doors to future brain implants that could restore movement in paralysed limbs.

A new Northwestern Medicine brain-machine technology delivers messages from the brain directly to the muscles – bypassing the spinal cord – to enable voluntary and complex movement of a paralyzed hand. The device could eventually be tested on, and perhaps aid, paralyzed patients.

Nerves Have Axons, Dendrites and Cell Bodies

  • Nerve cells are designed to respond to stimuli and transmit information over long distances
  • Nerve cell has 3 parts:
    • Cell body:
      • Has single nucleus
      • Has most of nerve cell metabolism, especially protein synthesis
      • Proteins made in cell body must be delivered to other parts of nerve
    • Axon:
      • Long cylinder, designed to transmit an electrical impulse
      • Can be several meters long in vertebrates (giraffe axons go from head to tip of spine)
      • Has axonal transport system for delivering proteins to ends of cell

Brain Waves Can 'Write' on a Computer in Early Tests, Researchers Show

Neuroscientists at the Mayo Clinic campus in Jacksonville, Fla., have demonstrated how brain waves can be used to type alphanumerical characters on a computer screen. By merely focusing on the “q” in a matrix of letters, for example, that “q” appears on the monitor.

Researchers say these findings, presented at the 2009 annual meeting of the American Epilepsy Society, represent concrete progress toward a mind-machine interface that may, one day, help people with a variety of disorders control devices, such as prosthetic arms and legs. These disorders include Lou Gehrig’s disease and spinal cord injuries, among many others.
