16
Q

Premotor Cortex function

A

Responsible for complex and skilled movements required for speech, hand manipluations, and eye-hand co-ordination

17
Q

Prefrontal Cortex function

A

Cognitive functions such as reasoning, thinking, pragmatism, planning

18
Q

Inferior front gyrus function

A

Important for speech production

19
Q

Lesions to frontal lobe

A

impairment of memory, inattentiveness, behavior disorders, difficulty in learning new info.

20
Q

Parietal Lobe function

A

Perception of somatic sensation, and spatial orientation, memory

21
Q

Postcentral gyrus

A

Primary sensory cortex

22
Q

All sensations received at primary sensory cortex are sent to:

A

Sensory association areas before awareness reached

23
Q

Pathologies of pariental lobe

A

Contralateral sensory loss, perceptual disorders

24
Q

Temporal Lobe, three gyri

A

Superior, middle and inferior

25
Heschl's gyri
Primary auditory cortex
26
Wernicke's area
Languague association cortex
27
Lesions of Wernicke's area
Fluent aphasia, Impairement of language comprehension
28
Wernicke's area is interconnected to the Broca's area via:
Arcuate Fasciculus
29
Arcuate Fasciculus damage results in:
Conduction Aphasia
30
Conduction aphasia
Auditory comprehension and speech articulation are preserved by people find it difficult to repeat heard speech.
31
Primary visual cortex is concentrated in:
The calcarine Sulcus
32
Lingual Gyrus plays role in:
Dreaming and vision, and recognizing words
33
Agnosia
Loss of ability to recognize visual images
34
Dyslexic
Disability when reading or writing
35
Insular Lobe is also known as:
The island of Reil, plays role in limbic system
36
Lesion to brocas area
Motor aphasia, understand speech but cannot produce meaningful sounds
37
Disorders as a result of lesions to Parietal lobe
Dyslexia, dysgraphia, dyscaculia, Gerstmann's syndrome
38
Unilateral lesion of primary visual cortex
near-total blindness in opposite visual feel
39
Lesions to visual association areas
visual agnosia, dyslexia, impaired visual memories
