Supplementary material I

This comprehensive overview explores the intricate relationship between deep brain stimulation, muscle coordination, and neural control involved in voluntary movements. From the primary motor cortex to the basal ganglia and thalamus, we examine how these brain regions work together to facilitate actions like walking, dancing, and riding a bike. Additionally, we delve into innovative techniques such as fMRI and their applications in lie detection and personal profiling, highlighting how computers analyze data to find meaningful connections between individuals.

Presentation Transcript

  1. Supplementary material I • Deep brain stimulation (12 minutes) • http://www.youtube.com/watch?v=ksjHNbb6NFQ&feature=related ch 2

  2. Controlling voluntary hand movement involves the coordination of thousands of muscle fibers

  3. Coordination of muscles • A toddler learns to walk. • A novice dancer tries to balance his posture. • Learn to ride a bike first time.

  4. PMC • The coordination of the muscle fibers is controlled by the cortical and sub-cortical loop. PMC: Primary Motor Cortex PMC Basal ganglia Basal ganglia thalamus Thalamus

  5. The coordination of the muscle fibers is controlled by the cortical and sub-cortical loop. PMC: Primary Motor Cortex PMC Basal ganglia thalamus

  6. Supplementary material II • fMRI and a lie detector (10min) • http://www.youtube.com/watch?v=Cwda7YWK0WQ

  7. How does the computer identify the thought? • E-harmony.com

  8. Q1: Do you like beer? 1. very much; 2. so so; 3. neutral; 4. not really; 5 not at all Q2: Do you like coffee? 1. very much; 2. so so; 3. neutral; 4. not really; 5 not at all Q3: Do you like to have a vacation in Paris? 1. very much; 2. so so; 3. neutral; 4. not really; 5 not at all ……. …….

  9. Your profile becomes a collection of numbers and your profile (numbers) is stored in the e-harmony.com web servers • Tom Cruise=[Q1=2, Q2=1, Q3=5,…., ] • To find good matches for you, the computer calculates the distance between you (=[Q1=2, Q2=1, Q3=5,…., ]) and all others registered in the e-harmony.com server

  10. Calculate the distance between you and all others. And return the one that shows the shortest distance. • Tom Cruise= [1, 4, 2,,….] • Susan =[3, 2, 1,…] • Kathy =[1, 2, 4, …] • Mary = [1, 4, 3,…] • And find the one that has the shortest distance

  11. Your Screwdriver= [1, 4, 2,,….] Screwdriver= [1, 4, 2,,….] Igloo=[3, 2, 1,…] bed=[1, 2, 4, …] desk= [1, 1, 3,…]
