  This paper reviews the main perspectives of language acquisition and language
comprehension. In language acquisition, we have reviewed the different types of
language acquisitions like first language acquisition, second language
acquisition, sign language acquisition and skill acquisition. The experimental
techniques for neurolinguistic acquisition detection is also discussed. The
findings of experiments for acquisition detection is also discussed, it
includes the region of brain activated after acquisition. Findings shows that
the different types of acquisition involve different regions of the brain. In
language comprehension, native language comprehension and bilingual's
comprehension has been considered. Comprehension involve different brain
regions for different sentence or word comprehension depending upon their
semantic and syntax. The different fMRIEEG analysis techniques (statistical or
graph theoretical) are also discoursed in our review. Tools for
neurolinguistics computations are also discussed.
