Abstract
Language is the specie-specific communication system of
homo sapiens and it is a marvelous device for exchanging
information about mental states. The biological side of
language is the subject of increasing research and advances
are possible because of the growing sophistication of
available experimental techniques and equipment. The study
of languages in the brain and the brain functions involved in
speech processing is called neurolinguistics of the many
questions of interest to neurolinguists three are fundamental
1). Where in the brain are speech and language localized? 2)
How does the nervous system function to encode and decode
speech and language? 3) Are the components of language i-e
phonology, syntax, semantics, neuroanatomically distinct
and therefore vulnerable to separate impairment. Two areas
of the left hemisphere are especially important in language
processing i-e Broca’s area and wernike area. Evidence for
this localization comes from studies of aphasia are
identifiable according to impairments to different aspects of
language there tend to be associated with damage to different
brain regions. Different brain scanning technologies such as
electroencephalography (EEG), magnetoencephalograph
(MEG), positron emission tomography (PET), and functional
magnetic resonance imaging provide us images of the brain
at work and have led to a growth in our knowledge about the
physiological mechanisms underlying the knowledge of
language. This paper is an attempt to introduce all these
aspects of neurolinguistics and new researcher about
language and brain to the reader.
