Parietal Lobe

Aka: Parietal Lobe, Parietal Lobe Function, Cerebral Parietal Lobe, Homunculus
  1. Physiology: Homunculus
    1. Homunculus is a graphical representation of sensory and motor control
    2. Man standing at the midline between the two Cerebral Hemispheres
      1. Legs are above the falx cerebri at the medial Parietal Lobe (Anterior Cerebral Artery)
      2. Legs are relatively small compared to arms and head
        1. Represents fewer overall Neurons dedicated to leg motor and sensory control
    3. Man is bending at the waist over the top of the Parietal Lobe
      1. Legs and head extend over the lateral Parietal Lobe (Middle Cerebral Artery)
      2. Arms and head are relatively large
        1. Represents greater overall Neurons dedicated to arm/head motor and sensory control
  2. Signs: Brain Lesions
    1. Receptive Aphasia
    2. Sensory loss
    3. Spatial Disorientation
    4. Hemianopia
  3. Exam
    1. Cognitive Dominant
      1. Names fingers
      2. Knows left and right
      3. Performs calculations on paper
      4. Reading
    2. Cognitive Non-Dominant
      1. Constructs copy of matchstick figure made by examiner
  4. References

Parietal Lobe (C0030560)

Definition (FMA) Parietal lobe is the one of five lobes of the cerebral hemisphere which occupies the dorsal-posterior portion of the hemisphere. It is bounded by the central sulcus on its anterior border and and by the longitudinal cerebral fissure on its medial border. Posteriorly it shares an arbitrary border with the occipital lobe.
Definition (NCI_CDISC) One of the lobes of the cerebral hemisphere located superiorly to the occipital lobe and posteriorly to the frontal lobe. Cognition and visuospatial processing are its main function. (NCI)
Definition (NCI) One of the lobes of the cerebral hemisphere located superiorly to the occipital lobe and posteriorly to the frontal lobe. Cognition and visuospatial processing are its main functions.
Definition (MSH) Upper central part of the cerebral hemisphere. It is located posterior to central sulcus, anterior to the OCCIPITAL LOBE, and superior to the TEMPORAL LOBES.
