hemispheric lateralisation

• Brain lateralised into 2 hemispheres - functions localised to 1

  l-hemisphere: language

  r-hemisphere: visual + spatial

  some functions not laterlised

  • motor + somatosensory - cross-wired - corpus callous links the 2 + allows communication
• hemispheric lateralisation - evaluations

  • S: hemispheres process info differently: Fink et al: PET scans show RH used to attain global images, LH finer details
  • W: dominant sides of brain: 1000 people 7-29 use hemispheres for certain tasks, no evidence of dominant side - notion of r or l brain people wrong
