A
  1. Simple commands do not cross any cortex
    - Opening eyes is a “Simple Command”

Q

Frontal Lobe

-Dementia

A
  1. Pts w/ Dementia lose their frontal lobe when the brain shrinks so the brain can preserve the survival parts of the brain
  2. This causes a loss of inhibition and filter in dementia patients

Q

Temporal Lobe

-Loss of Smell or Inhibition Could Mean?

A

Q

Temporal Lobe

-4 F’s

A
  1. Self-Preservation and preservation of species “ANS”
  2. Fight or Flight
  3. Feeding & Fertility
18
Q

Temporal Lobe

-Sexual Function (Dopamine)

A
  1. Dopamine plays major part in pleasure centers and sexual function
  2. SSRI’s increase serotonin which is inversely related to dopamine
    - Pt may have low levels of Dopamine decreasing sexual function & pleasure
19
Q

Parietal Lobe

-Proprioception

A
  1. Knowing where you are in space even with eyes closed.
    - Proprioception is learned and developed
  2. “LEARNED”
  3. Babies learn that their mom will return even when she disappears from view
20
Q

Parietal Lobe

-Double Stimuli

A
  1. Injury to parietal lobe will cause someone to only feel one stimuli even if 2 are present at the same time
21
Q

Parietal Lobe

-Children and Body Neglect

A
  1. Kids will always neglect their body and will recognize touch on the face
  2. DON”T start assessment with head of face. Start with body
22
Q

Parietal Lobe

-Neglect Syndrome in Adults

A
  1. Someone with Right sided parietal lobe damage will neglect the left side of their body and not recognize it as self. It will be a foreign object.
23
Q

Parietal Lobe

-Graphesthesia

A
  1. Ability to recognize numbers when written on the palm of the hand.
