Neuroanatomy P2 - Lobes - Function & Damage

Frontal Lobe
1. Pre-Frontal
  1. Consists of 1) Dorsolateral prefrontal & 2) Inferior Prefrontal
    1. Dorsolateral prefrontal - Sends signals to parietal lobe
      1. Damage - can lead to dependency of environmental stimuli
        The Stroop Test - tests functionability
    2. Inferior prefrontal - sends signals to Amygdala
      1. Orbitofrontal
        Cognitive processes and decision making
  2. Function - deals with executive processes - recognition of consequences from actions
2. Damage
  1. Movement & speed/strength
  2. Speech - comprehension & structure
  3. Winsonsin Card Sorting - detects neurodegenerate diseases
  4. Impaired Sexual/Social Behav. (Addiction)
  5. Schizophrenia / Parkinsons
Parietal Lobe
1. Functions
  1. Object Recog.
  2. Spacial Navigation
  3. Movement
2. Damage
  1. Sensory
    1. Osomatognosis - No awareness of oneself.
    2. Thresholds Distorted
  2. Posterior Symptoms (found at back of lobe)
    1. Impaired Spac. Awareness and Language
    2. Finger Agonsia
    3. Apraxia - Inability to execute learned actions
Occupital Lobe
1. Function
  1. Colour
  2. Also plays role in Object Recog
  3. Motion / Position
2. Damage
  1. Visual Agnosia
    1. Loss of Vision - Color and Motion Deception
    2. Notes and Slides for further example of agnosia
Temporal Lobe
1. Consists of
  1. Limbic System
  2. Amygdala
  3. Hippocampus
2. Functions ranging from Visual AND Auditory
  1. Long Term Memory
3. Slide 33
4. Damage
  1. Visual / Auditory Perc. Disorder
  2. Memory / Organisation Disorders
  3. Personality Disorders
