Trumendous cortical redundancy |
|
|
According to lober, when does hydrocephaly has minimal impact in function? |
When the illness progresses bit by bit. |
|
|
According to lober, is asymetrical hydrocephaly posible? |
Yes it is |
|
|
According to Frep leinstein, Hydrocephaly is due to what ? |
A problem in white matter as ventrical enlarges rthe layer of fibers. Grey matter is sparred |

|
|
According to lober, why does he discurages the application of a shunt in people with hydrocephaly if they live normal lives? |
Shunt may have many complications not worth taking the risk. |

4x, no the brain regions grow at different rates. |
|
|
What are the two point of views regarding brain development? |
innate modules vs developmental dependent on learning and plasticity. |
|
|

|
|
According to Johnson, what are the 3 theories of developement? explain them. |
Maturational perspective: Anatomical maturation give rise to specific acquired cognitive functions. Interactive specialization approach: INter regional organization Skill learning hypothesis: Expertise give rise to physiological changes that can vary in areas. |
|
|
According to Johnson, what is the basic proof of maturational account and what is its problem. |
Many cortical regions giving rise to function concord with lesion studies done over the years Problem: Cannot account for the dynamic changes in pattern of cortical activation observed during post natal development or for activity in frontal lobes i early stage. |
|
|
