<prompt> Damage to categorical hemisphere usually leads toNormal speechIncreased speechDecreased speechSenseless, fluent speech  <response>: . categorical hemisphere is for sequential analytic processes and concerned with language function. lesion in it produce language disorders and it can be fluent,nonfluent and anomic aphasias.ASSOCIATION AREAS Association areas form the Inter-junction for various cerebral coex pas. They paicularly connect motor sensory areas. Mainly are associated with higher mental functions. Higher mental functions include speech, learning memory and intellectual functions insight, imagination etc., SENSORY ASSOCIATION AREA: This area provides primary interpretation of perceived sensation. Area included: 1. Brodmanns area 3,1,2 - Includes somatosensory coex. Perceives sensation of an object. 2. Brodmanns area 5 - Referred as Somatosensory association area. Interprets the shape, size, texture of sensation. 3. Brodmanns area 17 18 - Includes primary visual coex. Colors are perceived. 4. Brodmanns area 19 - Referred as Visual association area Identification of visual objects. 5. Brodmanns area 42 - Referred as Auditory association area. Interprets the meaning of heard sound. MOTOR ASSOCIATION AREA: Includes, Premotor area premotor coex supplementary motor area. INTERHEMISPHERICAL DIFFERENCES: Right left hemispheres are homologous symmetrical regions of cerebral coex on either side of brain. They are connected together by long association fibers carried by corpus callosum. FUNCTIONS OF HEMISPHERES: Functional asymmetry usually exists between hemispheres. Most impoant functional asymmetry is exhibited by Language. 1. Left hemisphere: Referred as DominantCategorical hemisphere Functions: Mainly represents language areas Wernickes area Brocas area - Both spoken written language. Visual processing of written language. Auditory processing of spoken language. Language-related motor functions like speech, reading writing. Detailed analytical abilities. Mathematical scientific skills with reasoning. Complex motor planning activities. Mainly involves sequential analytical process language. 2. Right hemisphere: Referred as Non-dominantRepresentation hemisphere Ref Harrison20th edition pg 2367
