Cognitive Neuroscience

1. Brain

   • Temporal Lobe
     • word understanding
     • memory/emotion
   • Frontal Lobe
     • problem solving
     • planning
     • word production
   • Occipital Lobe
     • Vision
   • Parietal Lobe

2. Cognitive Functions

   • Perception
     • pattern, object or face recognition
   • Language
   • Executive functions
     • decision making
     • problem solving
     • reasoning
   • Memory
     • long term
     • short term
   • Neuropsychological Tests
     • Visual Perception
       • Behavioral Inattention Test
         • Star cancelling
       • Wechsler Adult Intelligence Scale
         • Picture completion
         • Verbal IQ

       • Long term
         • California Verbal Learning Test
     • Attention
       • focused attention

3. Techniques to Study the Brain

   • Structural
     • CT
       • Computerised Tomography
     • MRI
       • Magnetic Resonance Imaging
       • shows density of different tissues in the brain
   • Functional
     • Electrical
       • EEG/ERP
         • ElectroEncephalogram/Event Related Potentials
         • measures electrical activity
       • MEG
         • MagnetoEncephalonogram
           • neural activity
             • shows active brain areas
     • Blood Flow
       • PET
         • Positron Emission Tomography
         • Radioactive positrons follow blood flow to active sites
       • fMRI
         • measures the position of blood with high oxygen levels
           • location of brain activity
       • fTCD
         • Cerebral brain flow velocity (CBFV)
         • ultrasound
         • gives information about direction and speed of red blood cells
   • Lesion studies
   • TMS
     • Transcranial Magnetic Stimulation

4. Lesion Studies

   • Lesion Studies
   • Frontal Lobe
     • Visual impairment
       • perseveration
     • inappropriate responses
   • Aphasia
     • Broca's
       • Word production/ finding impaired
     • Wernicke's
       • Word comprehension impaired
   • Split Brain
   • Perception and Action
