Question Answer
Extreme base of post central gyrus (43)taste
Precentral gyrus (4)primary voluntary motor control
Premotor area (6)secondary motor control (planning and mentally practicing movements, initiating some gross movements)
Middle frontal gyrus (8)Eye movement coordination
Opercular & triangular gyri (44)motor speech
Prefrontal cortex (9-12, 45-47)personality, motivation, planning, judgment, executive function, depth of feeling, impulse control
Postcentral gyrus (1, 2, 3)primary somatosensory area, including proprioception, taste
Superior Parietal lobule (5)interaction of sensory perception to environment (ex: sterognosis: knowing by touch)
Inferior Parietal lobule (40)contralateral integration of sensation with language, and with awareness of self and surroundings
Precuneus (Quadrate nucleus, 7)sensory evaluation, language processing, spatial relationships, time orientation
Cingulate Gyrus (23, 24, 33)memory, behavioral modes for food intake, drive, motivation, emotion
Transverse superior temporal gyrus (Gyrus of Heschl) (41)hearing perception
Wernicke's area (22)language understanding and formulation

Question Answer
Middle and inferior temporal gyri: Primary Olfactory Cortex (34)smell perception
Posterior (Occipitotemporal) Cortex (37)learning and memory (especially auditory information in dominant side and visual information in non-dominant side)
hippocampus (limbic system), parahippocampus (27, 28, 35, 36)formation of new memories, memory and emotion
Amygdala (limbic system)appropriate behavior, initiation and integration of somatic and autonomic responses, anxiety, 'social fears'
InsulaTaste, visceromotor control and viscerosensory perception, Calming when emotionally upset
Primary visual cortex (17)Perception of visual input
cuneate and lingual gyri (18, 19)Visual association areas for color, movement, depth perception
Limbic Systemincludes cingulate gyrus, parts of the thalamus, hippocampus, parahippocampus, amygdala, fornix, mammillary bodies
Fornix (limbic system)connects hippocampus to hypothalamus and other regions; mostly ipsilateral. Important in memories, emotions, mood
Hippocampusthe brain's 'map-maker' (physical and social) and a time-keeper among many other functions.
Basal gangliaform the 'extra-pyramidal system' controlling/modifying motor movements

Extreme base of post central Gyrus (43): taste
