THE HUMAN BRAIN

DIVIDED INTO TWO HALVES CALLED CEREBRAL HEMISPHERES

THE RIGHT HEMISPHERE CONTROL MATTERS RELATING TO 3D SPATIAL ACUITY

THE LEFT HEMISPHERE CONTROLS PATTERNS THAT PROGRESS STEP-BY-STEP IN A SINGLE DIMENSION

BRAIN LATERALIZATION

THE TWO HALVES OF THE HUMAN BRAIN ARE NOT EXACTLY ALIKE; EACH HEMISPHERE HAS FUNCTIONAL SPECIALIZATIONS

THE LEFT HEMISPHERE IN ONE PART PLAYS A PRIMARY ROLE IN SPEECH PRODUCTION (BROCA)

ANOTHER PART IN THE LEFT HEMISPHERE PRIMARILY CONCERNED WITH LANGUAGE COMPREHENSION (WERNICKE)

THE RELATION BETWEEN LANGUAGE AND THE LEFT HEMISPHERE

WADA TESTSIT PROVES THAT LANGUAGE IS SUPPRESSED WHEN THE

LEFT HEMISPHERE IS DISABLED DICHOTIC LISTENINGIT IS WHERE DIFFERENT MESSAGES ARE SENT

CONCURRENTLY INTO TWO EARS, THE DOMINATING MESSAGES ARE THOSE WHICH ARE SENT TO THE RIGHT EAR(THE ONE THAT CONNECT TO THE LEFT HEMISPHERE)

COMMISUROTOMYAN OPERATION IN WHICH THE CORPUS CALLOSUM WAS

SEVERED IN SEVERE CASES OF EPILEPSY, DISCONECTING THE TWO HEMISPHERE

APHASIALOGY

APHASIA IS CAUSED BY DAMAGE TO ONE OR MORE OF THE LANGUAGE AREAS OF THE BRAIN

APHASIA CLASIFIED INTO TWO GROUPS BROCA’S APHASIA AND WERNICKE’S APHASIA

BROCA’S APHASIA

JAY (2002:38) DESCRIBES BROCA’S APHASIA AS THE RESULT OF THE DAMAGE IN THE THIRD CONVOLUTION OF THE FRONTAL LOBE NEAR THE MOTOR CORTEX

CHARACTERIZED BY MEANINGFUL BUT SHORTENED SPEECH AND LACK OF

WERNICKE’S APHASIA
