  • 1 EEG

  • 1.1 History

  • Who was Berger H. And what did he work on?

    - German scientist, worked on EEG in his free time
    - tried capturing brain potential from scalp
  • What did Berger H publish in 1929?

    His first results on alpha-waves from the brain of his son
  • Who was the first person recording EEG in 1912?

    Russian scientist Pradvdich Neminski
  • 1.2 EEG signals

    This is a preview. There are 8 more flashcards available for chapter 1.2

  • The brain consists of white and grey matter, the cortex consists of 6 layers. Which 2 are the most relevant for EEG?

    - layer 1 and 5
    - pyramidalis interna neurons with dendrites point all the way upwards from layer 5 to 1
  • How are pyramidal interns neurons organized?

    In orderly vertical fashion
  • Input measured with EEG comes from:

    Layer 5 
    - only layer 5 and 1 can be measured from the scalp
  • Why is it difficult to find out the input of just one neuron?

    Because EPSP and IPSP is a continuous effort, from 1000s of input at the same time
  • What does spontaneous EEG mean?

    Is a mix of all frequency's bands
  • Explain the study about resting state activity and gambling behavior.

    - used low gambling task in which low risk behavior will eventually make people earn more
    - depending on asymmetry of the PFC in the left side of brain --> more reward driven and take more risks
  • Explain the study where they used symmetrical frontal cortical activity to measure aggression.

    - participants had to write essays about different political topic (like abortion)
    - after they all got EEG + envelope
    - some instructed to do nothing, others to contract their right hand, last group their left hand
    - after EEG manipulation + contracting: social setup where participant and insulter played in punishing task
    --> Found: people who were in assaulted condition + hand to squeeze right hand punished the insulter the most
    => squeezing right hand --> increased activity on left side of brain in frontal area --> most pronounced anger
