background and aim: human beings receive a variety of sounds in their everyday lives. these sounds are generated by different sources, and are heard simultaneously or with a small time sequence. a characteristic of the auditory system is its ability to analyze complex sounds, and to make decisions about the source of each constituent part of these sounds. the present study intends to assess nor...

background and aim: auditory temporal resolution skill is calculated according to the minimum required time to analyze or integrate acoustic events. this skill, which is essential for speech perception, was evaluated by gap detection tests. the aim of this study was to determine the presence or absence of any differences between the right and left ear in the gap detection test. methods: after p...

Recent anatomical and electrophysiological evidence in primates indicates the presence of direct connections between primary auditory and primary visual cortex that constitute cross-modal systems. We examined the intrinsic functional connectivity (fcMRI) of putative primary auditory cortex in 32 young adults during resting state scanning. We found that the medial Heschl's gyrus was strongly cou...

Structural and functional features of various cerebral cortices have been extensively explored in neuroscience research. We used manganese-enhanced MRI, a non-invasive method for examining stimulus-dependent activity in the whole brain, to investigate the activity in the layers of primary cortices and sensory, such as auditory and olfactory, pathways under acoustic stimulation. Male Sprague-Daw...
