In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

On January 18, 2013, Caltech hosted TEDxCaltech: The Brain, a forward-looking celebration of humankind's quest to understand the brain, by exploring the past, present and future of neuroscience. Visit TEDxCaltech.com for more details.

  • I believe people with ADHD have a problem with doing, not necessarily with understanding or learning. While someone may take time to learn something and consistently do the work to demonstrate to others and themselves that they know, someone with ADHD may learn but not do for an extended period of time, and then do only when they deem it very necessary. I think it has something to do with our short term working memory vs long term "retention" memory in conjunction with an involuntary survival mechanism (we do not want to expend unnecessary energy - because most tasks done in modern society are not actually necessary for survival)
  • Bravo. As a 61 year old lady with adhd, I pray you can help future generations of adhd suffferers with your research. ADHD has made my life a very difficult one. I wouldn’t wish it upon anyone. May God bless your work. If you ever need a human for your trials, I gladly volunteer.
  • I was diagnosed with ADHD at age 33. The 1st time I took the stimulant medicine it was like having the correct prescription in my proverbial eye glasses for the 1st time. Learning deficit? NO. Ability to concentrate and think clearly? YES!! Stimulant medicine makes me take a nap for 30 min, then, brain---GO!!

    The concept that ADHD is a dopamine problem, either the lack of or the inability of the neurotransmitters to adequately deliver it to the proper part's of the brain makes absolute sence. It explains the symptoms including drug addiction, depression and disorganization. It also covers the higher rate of nicotine addiction and obesity amount those with ADHD.
  • @shenova
    i am adhd and dyslexic. i can’t wait for them to figure out how to do this for humans. it makes so much since.
  • @orbik_fin
    It should be noted that a label like ADHD or autism really describes just visible behavior rather than its neurological origins, and many quite different types of "disorders" may be (wrongly) grouped under one name. Essentially, what the speaker describes is just one type of neurological difference which produces ADHD-like symptoms, and the results of this research should be applied to humans with caution.
  • Click the little gear icon to set the video speed to 1.5x If you already do this you have ADHD
  • Cool video. As someone with ADHD and siblings with the disorder as well, medication can be a total game changer. However, ADHD does seem to offer some selected advantage to some, if they can find jobs and lifestyles that work for them. I can confidently say that pretty much all of the successful entrepreneurs I know have pretty much all of the symptoms of ADHD. Restless, impulsive, risk taking, lack of or poor sleep, etc.. But the difference between success and failure seems to be that some people have found ways to work with their STRENGTHS rather than to get involved in things that expose their weaknesses. Meds can help in this regard... But ADHD is pretty interesting. It's definitely a real thing, but I think people are affected in different ways. Great video.

    I LOVED THAT THIS TOUCHED ON THE EMOTION ASPECT! I no longer have to worry if I am the only human who contemplates the relative importance of emotion by and for, to and from everything experienced in life.
  • Wow, really grateful for this discovery and talk! <3. (ADHD sufferer)
  • @Nota769
    Makes sooo much sense. It’s evoking images of people over treated just to possibly affect one or two symptoms while the rest of the person is barely awake type of thing
  • The only problem with being schizophrenic is that people don't accept you, you don't have a legitimized role, and you can't be comfortable about yourself. It's a social problem. Acceptance and compassion turn suffering into just a difficult moment. It's about recognizing the value of human diversity, and the talents and pitfalls of all personalities and behaviors.
  • Fascinating talk! The analogy of the oil on the car engine fits many medical approaches! I have a major concern with your talk automatically connecting learning disabilities with ADHD. While concentration is certainly a factor for us, the two do not always go hand in hand! I'm now 64. I was diagnosed with ADHD in the late 90s. I graduated in the top 10 of my class, and my daughter, now 41, was a presidential scholar, who rated in the top 3% of the nation. Our biggest challenges are being over-stimulated, especially her. She learns equally well in all styles. Neither of us needed tutoring for lack of ability, we needed support in how to manage how our active brains work. Stimulant meds help, and still, what we truly need is for society and people in positions like you to shed the notion that our cognitive abilities are lacking. She didn't get the accommodations she needed in high school because they erroneously thought that "Because she tested out of first year French" she didn't really have ADHD, because students with that have problems with language". She is now a professional writer. Your work is indeed promising, but please learn more about us as a spectrum of people, and don't limit us in your teaching to others. I highly recommend Jessica McCabe and her Ted Talk. She also has a You tube channel called "How To ADHD". Perhaps it will give you more insight into our worlds.
  • Now that wás interesting!! And entertaining without losing complex content or derail into condescension! Loved it.
  • Great talk, and absolutely brilliant study! Wowww!!! Thank you for your work and dedication to this very important but often overlooked topic!!! I pray you are successful in getting us some REAL and much needed help to get our conditions in check...they are literally destroying our lives, our Relationships, our careers, our families etc...etc...
  • @mauronarf
    Loved the presentation and how cleverly the experiments were carried out Amazing! Great work!
  • I agree with the need for more efficient targeting. As far as disorders go, I always tell people that medication always goes so far and the heavy lifting is the cognitive side of things. Because of the relative inefficiency of broader acting drugs, the most you get is more headroom to be able to make conscious decisions. As a psych graduate with both ADHD and Major Depression, I'm looking forward to greater strides in medicine.
