Front 2

FRONTAL LOBE
name 4 Dysfunctions

Back 2

• Causes loss of the ability to solve problems; plan and initiate actions

• dorsal frontal lobe (controls voluntary movements) - weakness or paralysis can result

• Middle part of the frontal lobe - the ability to move the eyes, to perform complex movements in the correct sequence, or to say words may be impaired

• Frontal frontal lobe - the result may be impaired concentration and reduced fluency of speech

Front 3

PARIETAL LOBE
name 5 Functions

Back 3

•Associated with movement, orientation, recognition
•Sensation: tactile; proprioception
•Fine sensation (judgment of texture, weight, size, shape, area behind the primary sensory cortex)
*Some Language & reading
*Some Visual func

Front 4

PARIETAL LOBE
name 4 Dysfunctions

Back 4

• Front part of the parietal lobe on one side causes numbness and impairs sensation on the opposite side of the body, difficulty identifying a sensation's location and type
• Back part of the parietal lobe causes right-left disorientation; problems with calculations and drawing.
• Right Parietal Lobe - visuo-spatial deficits (ie. difficulty finding their way around new, or even familiar, places), can cause apraxia(inability to perform simple skilled tasks, ie. brushing the hair or dressing).
• Left Parietal Lobe – can disrupt a patient's ability to understand spoken and/or written language.

Front 5

OCCIPITAL LOBE
name 2 Functions

Back 5

• Associated with visual processing
• Contains association areas that help in the visual recognition of shapes and colors

Front 6

OCCIPITAL LOBE
name 2 Dysfunctions

Back 6

• Visual deficits
• Front part of the occipital lobe can impair the ability to recognize familiar objects and faces and to accurately interpret what is seen

Front 7

TEMPORAL LOBE
name 3 Functions

Back 7

•Help in sorting new information: Distinguishing one smell from another, and one sound from another
•Right-side Temporal Lobe - Mainly involved in visual memory: memory for pictures and faces
•Left Temporal Lobe - Mainly involved in verbal memory: memory for words and names, also known as short term memory

Front 8

TEMPORAL LOBE
name 3 Dysfunctions

Back 8

• Right temporal lobe - tends to impair memory for sounds and shapes.
• Left temporal lobe - drastically impair memory for words as well as the ability to understand language (causing receptive aphasia).
• Can sometimes cause personality changes such as humorlessness, extreme religiosity, loss of libido.

Front 9

What are the LEFT Hemisphere's Functions

Back 9

Logic
Linear
Verbal (using words to name, describe, define)
Temporal (time; sequencing things one after another)
Rational
Analytic
Abstract (using small bit of info to represent the whole)
Symbolic (using symbols to stand for something)
Digital

Front 10

What are the RIGHT Hemisphere's Functions

Back 10

Intuitive (hunches)
Holistic (perceiving the overall patterns)
Nonverbal: (Awareness of things, with minimal words)
Non-temporal
Non-rational (no facts needed, willing to suspend judgement)
Synthetic (putting together to form the whole)
Analogic (seeing relationships between things'
Concrete (relating to things as they are now)
Spatial (where things are in relation to other things)
