2

Stroke in Hippocampus and/or Amygdala

• Decreased emotional responses

 

Decreased responsiveness, aggression, fear, dominance and social interest

3

All neural roads lead to the

frontal lobes”

4

Frontal Lobe; All cortical tissue anterior to

central sulcus

6

motor • premotor • prefrontal

functional distinct regions of frontal lobe

7

Motor Movements Speech Production

Frontlal Lobe

8

Planning Organizing Problem solving

 

Frontal Lobe

9

Personality Behavior Emotions

Frontal Lobe

10

Selective attention

Frontal Lobe

11

• Primary motor cortex

Controls contralateral side of body • ‘motor homunculus’ •

12

Primary motor cortex

voluntary, skilled movements

13

• Premotor cortex

• sequencing, timing, and initiation of voluntary movements

14

Brocha's area of Frontal Lobe

speech production

15

Motor and pre-motor cortices of frontal lobe

direct control of movements through projections to spinal motor neurons and cranial nerve motor neurons

16

Motor and pre-motor cortices of frontal lobe

also projects to basal ganglia

17

lesion to Broca's Aphasia

Inability to speak fluently

Non-fluent speech

 Few words, short sentences, many pauses

18

lesion to 

Broca's Aphasia

Words produced with effort and sound distorted • Repetition is impaired

19

lesion to Broca's Aphasia

Repetition is impaired •

Comprehension is relatively intact • Awareness of mistakes

20

Prefrontal Cortex: Executive Functions of Frontal Lobe

effective and efficient goal-directed behavior; organization of behavior & cognition

21

Prefrontal Cortex of Frontal Lobe

Initiating - Inhibiting and Judgment

22

- Planning and organizing

and problem solving

Prefrontal Cortex

23

Selective attention

- Self-monitoring

Prefrontal Cortex

24

Abstract thinking and mental flexibility

Prefrontal Cortex:

25

frontal lobe lesion

Short-term memory impairment

• Loss of flexible thinking

26

Poor response inhibition

Damage to the Frontal Lobe

27

 

Inappropriate social & sexual behavior

Damage to the Frontal Lobe

28

Impaired judgment, abstract thinking, hypothesis testing and planning

Damage to the Frontal Lobe

29

• Difficulties using cues and information from the environment to direct, control, or change behavior

Damage to the Frontal Lobe

30

Occiptal lobe Separated from parietal and temporal lobes

by parieto-occiptal sulcus

31

Primary visual cortex is Brodmann area 17,

Occipital lobe
