Q

Carl Wernicke

A
  • proposed first model for organization of language
  • proposed that regions of the brain have different functions but still must interact to work correctly
  • identified that the left hemisphere was dominant for language

Q

Pierre Flourens

A
  • removed areas of cortex in animal brain and studied changes in behavior
    • refuted localization of function
    • showed no specialization for cortex
    • specialization for brain stem
    • remaining brain stem can substitute for function of cortex

Q

functional hierarchy of the brain

A
  • each successively higher level of nervous system controls more complex aspects of behavior
    • when higher levels are damaged, behavior becomes simpler, less evolved

  • inability to remember acquiring that skill
  • multiple memory systems

Q

neuron theory

A
  • neurons are the nerve cells in the brain and work as its functional units
  • neuron sends electrical signals along the dendrites and axons by chemical means
  • neurons communicate via synapses
  • neurons are plastic

Q

Vaidya et al 2020 - Lesion studies in Contemporary Neuroscience

main idea and evidence

A

Lesion studies are essential for neurobehavioral research and should be used in collaboration with modern imaging techniques

  • Compare/contrast imaging to lesion studies and their scopes
  • Figure 2 (schematics of different lesion methodologies)
  • Lesion studies can ID causal links vs association (imaging does this) and cited studies
  • Box 2 - strengths of studies (if you can jump through these hoops its effective and here’s why)
