Neurotechnology Introduces BrainAccess Development Kit

Neurotechnology Introduces BrainAccess Development Kit

VILNIUS, Lithuania, Aug. 12, 2020 – Neurotechnology today announced the launch of the BrainAccess Development Kit. The kit offers a full dry-contact electroencephalography (EEG) solution including the electrodes, headware, electroencephalograph, EEG signal acquisition and processing software and brain-computer interface (BCI) example algorithms. The BrainAccess Development Kit can be used to…

You know another thing that bugs me?  I barely have any backstory.  All anyone really knows about me is how terrible I am as a fiancé and a person.

I wasn’t always that way, though.  No one’s born being selfish and cruel.  I didn’t become a nurse just so I could get rich, you know. Not at first, anyway.

I know I’m not the only character whose backstory remains a mystery, but doesn’t anybody care what my motivations were for shooting that doctor, or for letting my fiancé die from a bullet wound?  Other than money and personal safety, I mean?

Was there ever a nicer, more humanitarian Alita who actually cared about others’ well-being, until something happened to change her attitude entirely?  Villains don’t just come out of thin air, after all.  Maybe I lost something or someone dear to me, and I started to develop some hatred for others?  Or perhaps I grew up in a poor family, and I craved financial security so I’d never have to return to that sort of life?  It could’ve been anything, really.

I could just tell you, I suppose, but no one ever asked me, did they?  Sorry, but you blew your chance to know.  You’ll just have to wonder about it for the rest of your lives.

Feel free to share any theories you might have come up with, though.  Ha ha ha!

“’Brain Waves’ Charted by New Machine,” The Globe and Mail. December 14, 1938. Page 15. --- Wide Possibilities Seen For Use of Apparatus In Field of Diagnosis --- ‘Electroencephalograph’ Will Determine, It Is Believed, Location and Extent of Tumors, and Aid in Finding Area of Brain in Which Epilepsy Has Origin; Equipment Installed In Hospitals --- Developed At University of Toronto --- Ways and means of recording by graph the wave forms of electrical impulses in the human brain, have been developed in the department of medical research in the University of Toronto. One such machine for recording these ‘brain waves’ has been installed in the department of the General Hospital devoted to brain surgery. Another is in process of installation in the Psychiatric Hospital. These pieces of apparatus, it was explained yesterday, can record changes in the electrical phenomena of the brain to the extent of one microvolt. They provide valuable possibilities as diagnostic agents, and are expected to be a practical clinical tool. By means of the mechanism, accurate information regarding the location and extent of brain tumors can be determined, it is believed, and localization of the area of the brain in which epilepsy originates can, in some cases, be achieved.

Pioneer Investigation Pioneer investigation in the study of electrical activity of the brain in Canada has been carried out by the department of medical research of the university in conjunction with the division of neuro-surgery and the department of medicine of the Toronto General Hospital, and in co-operative effort also with the Hospital for Sick Children and the Psychiatric Hospital. The first apparatus in Canada for recording human brain waves was built by research workers in the university’s department of medical research. Like the improved model in the General Hospital and that being built in the Psychiatric, it made possible the visible manifestation of the electrical phenomena of the brain. Contact with the patient is provided by insulated electrodes attached to various parts of the head, and the organs under study supply their own information when the currents they generate are amplified, recorded and interpreted. The ‘brain waves’ are recorded by an ink-writing oscillograph, and a study is made of any deviations from the normal. Several rooms in the General Hospital have been set aside for the work on ‘brain waves’ the infant science of what is known as electroencephalography. A special room has been devised where a patient in bed can be moved in for examination; it is ‘shielded’ against all electrical interference and insulated against noise. Study During Operations A further room has been provided for examination of patients in wheel chairs. Another is devoted to the apparatus, and a gallery ante-room to the brain operating room provides for study of the brain during operations. The fact that active brain cells generate minute electrical impulses was discovered by Berger in Germany in 1924. However, it is said, no one paid any attention to his findings, and it was not until ten years later that Adrian at Cambridge University ratified them. For the next two years, considerable work on ‘brain waves’ was carried on by Dr. and Mrs. Davis, Lennox and Gibbs at Harvard University.

Then at the end of 1935 and the beginning of 1936 the department of medical research of the University of Toronto embarked on the study of electrical impulses originating in the grey matter. Now a similar department is being started at McGill University.

Apparatus to Record ‘Brain Waves’ Built At University Three views of novel electrical equipment developed in the department of medical research in the University of Toronto for obtaining information on brain conditions as an aid in diagnosis and treatment. The work has been carried out in co-operation with the division of neuro-surgery and the department of medicine of the Toronto General Hospital and also with the Hospital for Sick Children and the Psychiatric Hospital. Research workers built the apparatus shown. At upper left are amplifiers for the brain waves; at upper right, operating table with recording gallery behind and, below, moving chart which writes down record of cerebral impulses. - Staff photos.

Hawking a technology that may assist Hawking

It's been awe-fully awe-inspiring to observe some of the technological advances that have enabled Stephen Hawking to continue communicating (and living). Ever more so inspiring, as his neurodegenerative/motor disease (amyotrophic lateral sclerosis) worsens with age, technology and medicine continue to improve. 

Hawking is currently using a pair of glasses, fitted with infrared sensors, that can turn even the most petty cheek twitches into words. Though it is a rather time-consuming process, it works, and has allowed for Hawking to continue sharing his thoughts with those whom are interested. 

Now, tech development is at such a stage where electroencephalograph technology is being used outside of hospitals and laboratories; and one of its applications can help to expedite this process. On that note, the human species (directed by Dr. Philip Low + colleagues) brings you, Neurovigil's iBrain. Soon, Hawking will be able to express himself simply by conjuring thoughts. What lies deep within the neural tracts of his mind is subject to a lot of curiosity... if he lives long enough for us to know, we may see for ourselves.

Tech That Does Your Body Good

When computers and the human body meet, great things can happen. That seems to be the ethos of tech entrepreneurs Hosain Rahman of Jawbone and Tan Lee of Emotiv, who work on extra-sensory reception.

Rahman spoke to Spencer Reiss of Wired about his company’s latest release, the health monitoring wristband “Up”, unveiled last November. As people move towards a more “quantified self” way of life, in which information about their bodies and their health becomes more and more desirable, Jawbone works to make gadgets that are beautiful and worth wearing.

The smartphone is now at the center of one’s digital life, said Rahman, and so their product is one that is controlled by a smartphone.

In an age of cloud computing and data mining, information about a person’s health can not only help people monitor their own health, but prevent brain illnesses, said Tan Lee, head of Emotiv.

Her company has launched a portable, more affordable version of an Electroencephalograph (EEG), which looks more like a DJ’s headphones than brain scanning technology. The devices already have a presence in over 90 countries.

The idea would be to compile a large-enough database, on a global scale, on to brain information retrieved by these devices to analyze and identify patterns that could help prevent or even revert certain illnesses, such as Alzheimer’s, Parkinson’s or Autism.
