Because it's Possible

  • A quick biofeedback primer

    NEUROFEEDBACK

    Neuro-feedback is a way to train brain activity. It is a non-invasive method of direct brain function training. It is helpful for people that have brain imbalances. Basically it is a kind of biofeedback, which teaches self-control of brain functions to subjects by measuring brain waves and providing a feedback signal. Brain waves tells us about how you feel and perform functions your it deals with stress levels, mood and overall brain function.

    Neurofeedback is also called EEG biofeedback it offers the treatments for persons that are suffering from some disorders like eating disorders and mood disorders. It stabilizes the brain to reduce anxiety and depression and early recovery from eating disorders mood disorders or other addictions.

    Some biofeedback provides audio, video, positive and negative feedback for desirable or undesirable activities.

    Here electrodes are used (which act like tiny microphones). These are placed on the patient scalp to record and amplify the EEG, or brainwaves and control auditory, visual, and/or tactile feedback which allows learning to take place. This operant learning initiates self-regulation and enhances relaxation, both necessary components of good brain function.

    Example A girl had trouble in sleeping and was unable to concentrate on objectives. From our diagnosis we concluded that she is suffering from anxiety disorder. Anxiety was utilizing most of the brain resources so she was unable to concentrate. We made the neurofeedback training program. We asked her to watch her favorite movie and we measured her brain activity when there was a loving scene there was a positive feedback and she was in non-anxious state and when there was some stressed scene she was in anxious state .With practice her skills improved and now she has no trouble in sleeping and she can concentrate well.

    How it works

    Our brain has the whole control of our body and is a complex system of chemical and electrical activities with about 100 billion neurons. Brain is designed to adapt to changes in the body and our environment and function well at all times. However, due to some genetics and environment condition brain does not function as well as it is able. The brain then becomes "dys-regulated".

    Simply put, a dysregulated brain tends to be over-stimulated when it is supposed to be calm and under-stimulated when it is supposed to be attentive. Sometimes, the brain self-corrects. When it doesn't, this dys-regulation becomes “the new normal”. So it makes sense that we should be able to re-train the brain to function optimally, the way it was designed. In neurofeedback training, we work in conjunction with other treatments. When your brain is better regulated, it allows you to change behavioirs and thoughts.

    Clinical applications It is used in some disorders like Attention deficit hyperactivity disorder Stroke Concussion Anxiety Enhancement of performance by surgeon’s athletes and artists Drug addiction PTSD Sleeping disorder Schizophrenia Insomnia Dyslexia Autistic spectrum disorder Epilepsy Depression

    ADVERSE EFFECTS

    There are some adverse effects of neurofeedback These includes Mental fatigue Return of old feeling in dreams Dizziness nausea and light sensitivity

  • Transcranial Alternating Current Stimulation (tACS)

    This is a new technology in the field of non –invasive electrical stimulation of the human brain and it is directly having an interference with the cortical rhythms. tACS is the external application of oscillating electrical currents and it has the ability to influence cortical excitability and activity. The expectation is to synchronise or desynchronize with a since resonance frequency through cortical oscillations. If this is applied for a long time it can lead to neuroplastic effects which is the ability to bring about changes to the brain in terms of function. When tACS is applied in phase it can lead to improvement in the cognition . Depending on the types of waves applied , for instance if alpha rhythms are applied it helps in improving the motor performance and application of beta intrusions can deteriorate it. tACS when applied with both alpha and beta frequencies can induce retinal phosphenes.

    When used in most studies tACS is used without a DC offset and the simple form uses sinusoidal stimulation. Also other wave forms are possible such as rectangular current shapes. The vital parameters which could shape the direction and duration of tACS induced effects happen to be the intensity, phase of stimulation and the frequency. However, the effect of tACS on motor evoked potential hasn’t been studied in detail yet. By increasing the duration of the transcranial direct current stimulation it results in a prolongation of the induced after effects.

    tACS may be agreat way to treat schizophrenic patients without detrimental effects. As we all know psychotic disorders are devastating mental diseases which are associated due to the dysfunctional brain networks. Gamma oscillations form a bioelectric market for celebral network disorders with therapeutic and prognostic capacity. It accompanies sensorimotor and cognitive deficits which is already present in schizophrenia.

    Thus, use of tACS would be an appropriate way to prevent therapeutic modality as it can influence cognitive performance as well as neural oscillations.

    tACS could play a grate role in helping some patients with abnormal oscillatory patterns and the same is true for Parkinson’s disease too. This is achieved through the attenuating or resetting of the anomalous oscillations. The Parkinson’s disease resting tremor can be bisected by tACS.

    Further, it is seen that by using a 200 kHz frequency it helps to treat patients with recurrent gliobastoma, which are tumours which can occur in the supportive brain tissue. When high stimulation frequency is applied to the transcranial region it inhibits the growth of treatment resistant tumours with basically no side effects.

    In conclusion tACS could become a great technique in the near future for treating patients with mental diseases.

  • A clarification on focus placebo

    We have started work on next years nocebo stimulator.....

  • Introducing the foc.us placebo

    Introducing an all new brain stimulator - the foc.us placebo

    The new foc.us placebo

    At focus we are dedicated to making research grade hardware available to those who want to try brain stimulation. Most studies incorporate sham stimulation in their experiments, and now you can too!

    tDCS uses a mild electric current to change the cortical excitability of the brain. Placebo betters this by using the belief of a mild electric current to change the cortical excitability of the brain. It also has zero side effects so is the safest way to try tDCS. Guaranteed.

    Don’t accept inferior sham tDCS stimulators; if you want sham use focus placebo.

    The foc.us placebo can deliver up to 2mA of sham tDCS stimulation, anywhere, anytime.

    Placebo could literally make anything better.

    Features wireless electrodes. Simply place the electrodes under the included headband and rotate the knob. Don’t worry if you don’t feel anything, just give it time.

    • 100% guaranteed safe!
    • Batteries not required
    • No known side effects reported

    “Ive been using sham stimulation for over 3 years and I’ve never felt better. Or worse. Or anything”

    Available today for $99 plus shipping.

  • 19th March foc.us update

    Go Flow in stock, v2 in stock, EEG in stock, v3 very nearly ready.

    tRCS mode is quite exciting. Few tweaks before we ship to improve it.

  • 7th March foc.us update

    tldr: foc.us/me annoying login bug fixed, v2 on way, v3 nearly ready, EEG in stock.

    foc.us is a "vertically integrated" company. What that means is we do everything ourselves. What that means is we are responsible for all the problems.

    Typically startups will outsource as much work as possible. So front-end stuff like logistics and e-commerce are handled by 3rd parties. During product development they will use wi-fi and bluetooth modules to save on certification and development time. Not to mention documentation, advertising and all the other thousand things required.

    But not at foc.us.

    That's not to say we haven't tried, we have. We just found that there are lots of problems when starting a business like this. And we found that the best way to get problems fixed was to own them. To take charge, if you will.

    I mention this because we've had a few website/shipping/app/firmware/supply-chain problems recently. But one by one they are almost resolved.

    It's difficult to say what "normal service" is, but it will be resumed shortly :)

    P.S. What do you think about the sports caps in black?

  • 新年快乐 - Happy New Year

    Happy New Year to all our friends in China!

    Picture from CES 2018 Las Vegas @ Bellagio Hotel - Year of the Dog.

  • CES, V3 and More - 19th January Update

    It's been a busy few months at foc.us towers. Here is a quick update of what's happening.

    The successor to the massively popular V2, the V3 is now available to buy.

    We're very excited because it includes a new type of stimulation invented here at foc.us studios - tRCS - Rippled Current.

    What is rippled current? It's a dynamic-time frequncy designed to increase peak alpha brainwaves. Read more here.

    tRCS is only available from the focus V3 (coming soon to EEG Dev Kit) so order here to get your alpha vision.

    Talking of brainwaves, the EEG Only Dev Kit is now in stock for next day shipping. All 2nd batch EEG orders will ship by the end of January.

    Go Flow Sports orders will also ship shortly, small delay with inbound stock from China.

    Lastly, CES was great fun. Thanks to everyone who said hello. See you again next year!

  • EEG Dev Kit Update December 28th

    tl:dr; EEG Dev Kit production completed. Electrodes almost finished. Orders shipping soon.

    Manufacturing electronic products can be difficult.

    Making 10 is easy - they can be done by hand. Making 10k is easy, everything is on reels direct from the supplier.

    But making 100 or 300 or 1k is where the dragons be.

    Big manufacturers don't want small orders like this. Components are not sourced on reels so must be checked individually. Setup time and overhead fees are disproportionate. Everything is a PITA. This is what foc.us fights with.

    But today's story has a happy ending.

    Our new PCBA factory is much bigger than the two we have used before:

    They use the same pick and place machines:

    But the quality control is WAY better as they x-ray every PCB one by one.

    The EEG Dev Kit has nine BGA components so this step is crucial in identifying any possible problems.

    This has resulted in the best yields we've ever seen - 99%!

    The cost of EEG components is crazy high, so a yield of 1% (it's actually less than 1%, I rounded up) is fantastic news for us.

    Each Dev Kit includes three pcbs - main, sockets and electrodes. This is the sockets PCB exiting the oven.

    All that remains to complete is the new EEG+ electrodes. They are nearly done and will be very soon.

    We will be using this factory for all PCB work henceforth. If they can get 99% yield for EEG we expect 110% for Go Flow ;)
