functional areas

From MRCEM success:

Area	Function	Lesion
Primary motor cortex	Contralateral movement of voluntary muscles	Contralateral UMN weakness/paralysis
Premotor cortex	Role in coordination of complex movements	Apraxia, UMN signs
Supplementary motor cortex	Role in programming complex motor sequences	Inability to plan sequence of complex movements
Frontal eye field	Conjugate deviation of the eyes to the opposite side	Conjugate deviation of the eyes towards the side of the lesion (and away from the side of weakness)
Broca speech area (dominant hemisphere)	Speech production	Expressive dysphasia (unintelligible words)
Prefrontal cortex	Higher intellect, problem-solving, judgement, personality, emotion and mood, central control of micturition	Inappropriate social behavior, difficulty in adaptation and loss of initiative, primitive reflexes, inability to concentrate, incontinence
