Uses the bold oxygenation level dependent on functional magnetic resonance imaging (BOLD-fMRI) to observe the volume and intensity of the activated auditory cortex evoked by pure tone stimuli in healthy subjects,analyzes the volume and intensity of two hemi- spheres of activated auditory cortex quantitatively,and compares the difference of auditory cortex between left and right hemispheres.

Age-dependent expression of NMDA receptor subunit NR2B protein in rat auditory cortex;

Age-dependent expression of NMDA receptor subunit NR2B mRNA in the rat auditory cortex;

The auditory cortex(area 41 ) were divided artifically into four subareas, which include area 41A,area 41B,area 41C and area 41D according to four quadrants,for studying the axonal topographic organization of the callosal neurons in different parts of the auditory cortex(area 41 ) in the corpus callosum.

Objective To investigate functional magnetic resonance imaging(fMRI) of visual cortex of blood oxygenation level dependent(BOLD).

Following BDA placement in visual cortex, labeled callosal axons were seen in contralateral visual cortex and retrosplenial cortex (area 29).

Results:Compared with normal controls,there was no obvious move in the location of evoked visual cortex and no significant difference for the magnetic frequency evoked by parietal lobe,frontal lobe,temporal lobe and occipital lobe for patients of schizophrenia group when viewed by different emotional pictures.
