    The fact that someone from Mozambique has access to an MIT lecture from the comfort of their couch is simply mind-blowing. By the way, I was surprised to hear that Professor Nancy has visited Mozambique! Anyways, thank you MIT for giving us access to high quality educational materials for free.

    Your work regarding Neurology is what got me into studying human brain, specifically since I was 15 years old, I started to study Psychiatry, know General Medicine it is the easy one, then after hearing Your talks, decided to focus on Neurology. I was misdiagnosed with bipolar, when I really had high functioning autism. Worked through therapy, mainly logotherapy, to improve speech, social phobia, and agoraphobia.

    Dear Professor, the claim that nobody had done the reverbs before is not true. Many years ago, I was an acoustic engineer and my field was architectural acoustics. Specifically, I was designing acoustic environment in a room for different purpose e.g. music, speech etc. One of the key properties we study is the reverberation time of the room and there many many measurements of different type of rooms and the fact that sound level decays has been very well known in the field of architectural acoustics. Just thought I’d point it out. Happy to offer more details if you are interested.

    12:04 He asked about the "intensity or volume" and the answer was that it isn't well depicted on that graph. But I would have thought that the graph literally shows the overall loudness by how tall the squiggles are. They show the measured amplitude of the pressure wave at any given time, i.e. loudness/volume.

    Two random ideas off the top of my head about why the primary audio cortex might have two areas for high frequencies.
    1. Backup/error detection. It would be evolutionary beneficial to still be able to hear if one side got damaged.
    2. Each side might be subtly different, perhaps one side is close to being the true signal and the other is processed in some way. Some form of computation could take both these signals and use this to perform another function such as helping figure out sound direction or perform noise reduction to the signal to help us pick out the sound we're interested in.

      a vowel is a long-lasting sound - a crochet; a consonant is a fricative - a semiquaver - it doesn't last. the pictures don't reveal anything hidden in the sound. but they're pretty pictures :)

    I wonder if the speech selective cortical region is still active for speech that contains phonemes that are not found in the language the individual speaks. I.e. does the brain detect as speech the clicks from Xhosa for example? Or whether there's a difference for voiced/unvoiced clicks. Or even if the context of seeing a person making those sounds increases activation.

      Not sure what you're saying. Are you saying you don't process thought in language? This is not available to you through introspection. However, you might not experience inner language the way that is typical.
      What do you mean you remember from since you were 12 or younger?

      #14, 22 did not have lectures, they were student breakout groups/discussions.
      #17 no notes given on why it was the video not recorded. The topic was MEG Decoding and RSA.

    Wow.
    In Portuguese we have the word "confundir", which is a lot more of a common word than "confound" in English! I just commented this because I've used English for 14 years and had never directly translated the word "confundir".

    • @excitedaboutlearning1639
      @excitedaboutlearning1639 2 года назад

      Confound is a specific term that is used in scientific literature. I'm not completely certain of its meaning, but I'm still pretty confident. In academic English, confounding means the following:
      something has happened and a researcher intends to map the causal relations. That is, what caused the thing that happened. But instead of choosing the right cause they choose the wrong one, thinking that it's the right one.
      The wrong cause would be called a confounding variable, because it appears to the researcher as the cause of something when in reality it's not. For example, you can have the following situation: "Students who have trouble understanding mathematics disturb the class."
      So, you may think that the students having trouble with mathematics is the cause of them disturbing the class. So you map a causal relation between having trouble understanding mathematics and disturbing the class, but actually, it can be that they only disturb the class if they don't get help, so then the real cause is not having trouble understanding mathematics, but not getting help is the real cause.
      Having trouble understanding mathematics would be the confounding variable in this cause, because it only creates the conditions in which the real cause - not getting help - can take place.
