Q

Failure of brain cleavage

A

Holoprosencephaly

17
Q

No cleavage at all resulting in no distinct cerebral hemispheres; no corpus callosum

A

Alobar form

18
Q

Some cleavage and developmental of right and left hemispheres, but incomplete; no corpus callosum

A

Semilobar form

19
Q

Least severe; brain looks normal, but abnormal connections between hemispheres

A

Lobar form

20
Q

Period of the birth of new neurons; new neurons will be gray and white matter of cerebral hemispheres

A

Neural proliferation
