The brainfunctions as awhole, but... Injuries to the brain can affect specific regions, making it difficult to interpret and treat the injury. Properties suchasconsciousness, language,emotion andintelligence are not situated in only one region.
Scientistsare discovering more andmore about the complex relationships between cognitive functionsand the structures of the brain itself; these numerousinterconnections need to be understood so that thebrains can work as a whole.
This picture shows an image of a thought, you can clearly see that al brain area's are used.
Itlooks like a big'road map',with busyjunctionsandhighways thatintersect andareas thatare closelylinkedto each other by80-100millionneurons.Eachneuronhas 1,000to 10,000connections....

The brain(cerebrum)resembles alarge walnutwithgrooves andturns. Thebrainconsists of twohemispheres.Generally speaking,the left hemisphereis involved inabilities likeverballanguage,andthe right hemisphere more innonverbalcapibilities or functions. Theleft braincontrols theright side of the bodyand vice versa.
Scientistsare still discoveringmore functionsthat tended previouslyto be attributed to the 'other'brain hemisphere.Thebrainworks as awhole.Thehemispheresaredivided intolobesagain.
DAMAGEin the left hemisphere Remember: One personwith damage in this hemisphere may haveone ortwoof these symptoms, while another may have multiple symptoms.
Possible symptoms may include:
disorders,paralysisorsensory disturbanceson the right sideof the body
visionon the right sideof both eyesmay have decreased(hemianopia)
Remember: One person with damage in the hindbrains may haveone ortwo of thesesymptoms, while another may have several:
problems with balance/ balance
Fine motor Coordination
Balance and Equilibrium
alternating visual depth perception or sudden blurred vision
switching from onetask to anotheris difficult
logical thinking, planning ability may be impaired
abstract thinking ability may be damaged
memorymay be damaged
visual-spatial organizational ability may be damaged
speaking abilitymay be damaged
DAMAGE IN PONS Locked insyndrome
DAMAGEIN FRONTAL LOBE Remember: One person with damage in the frontal lobemay haveone ortwo of thesesymptoms, while another may have several:
The frontal lobe effects can be divided intothreespecific areas:
Damage toside /back offrontal lobe:
inflexiblebehavior disorientation difficulties learningfromownmistakes difficultto correct reducedabstractthinking planning problems organizational problems short-term memory disturbance memorydisturbance attention deficit disorder ability to organize informationreduced apraxia neglect cannot stopan act Broca'sAphasia(left) no sense ofnonverbalaffairs (right) sided paralysis (hemiplegia)
Damagein the middleoffrontal lobe:
depending on the environment initiative willchange loss ofpower emotionally not happy not sad apathy
poor movement paralysis onside- of the affectedpart of the brain
Damageintheregionof the eye socketoffrontal lobe(frontal orbital):
lack of inhibition impulsive poorself-correction loss of ability to recognize right and wrong of loss of a 'moral compass' Pays little/no attention toothers inappropriatejokes, tactlessness sense of smellis disturbed
