Understanding the auditory-fMRI
نویسنده
چکیده
The neuroanatomy of the auditory system is well established (Brodal, 1998). Input to the brainstem comes through VIII cranial nerve. First station is cochlear nucleus. From the cochlear nucleus, auditory information is split in two. Some nerve fibers going to the ventral cochlear nucleus synapse on their target cells with giant, hand-like terminals. This serves as timing of the signal. The ventral cochlear nucleus cells then project to the superior olives. This projection is bilateral [Fig 1]. In the superior olive, the differences in timing and loudness of the sound in each ear are compared, and from this it is determined the direction the sound comes from.

Combined MEG and fMRI model
An integrated model for magnetoencephalography (MEG) and functional Magnetic Resonance Imaging (fMRI) is proposed. In the proposed model, MEG and fMRI outputs are related to the corresponding aspects of neural activities in a voxel. Post synaptic potentials (PSPs) and action potentials (APs) are two main signals generated by neural activities. In the model, both of MEG and fMRI are related to t...
متن کاملFeature Selection Based on Genetic Algorithm in the Diagnosis of Autism Disorder by fMRI
Background: Autism Spectrum Disorder (ASD) occurs based on the continuous deficit in a person’s verbal skills, visual, auditory, touch, and social behavior. Over the last two decades, one of the most important approaches in studying brain functions in autistic persons is using functional Magnetic Resonance Imaging (fMRI). Objectives: It is common to use all brain regions in functional extracti...
متن کاملfMRI of the auditory system: understanding the neural basis of auditory gestalt.
Functional magnetic resonance imaging (fMRI) has rapidly become the most widely used imaging method for studying brain functions in humans. This is a result of its extreme flexibility of use and of the astonishingly detailed spatial and temporal information it provides. Nevertheless, until very recently, the study of the auditory system has progressed at a considerably slower pace compared to o...
متن کاملFunctional Imaging Reveals Numerous Fields in the Monkey Auditory Cortex
Anatomical studies propose that the primate auditory cortex contains more fields than have actually been functionally confirmed or described. Spatially resolved functional magnetic resonance imaging (fMRI) with carefully designed acoustical stimulation could be ideally suited to extend our understanding of the processing within these fields. However, after numerous experiments in humans, many a...
متن کاملFunctional imaging of auditory cortex in adult cats using high-field fMRI.
Current knowledge of sensory processing in the mammalian auditory system is mainly derived from electrophysiological studies in a variety of animal models, including monkeys, ferrets, bats, rodents, and cats. In order to draw suitable parallels between human and animal models of auditory function, it is important to establish a bridge between human functional imaging studies and animal electrop...
متن کاملAuditory processing skills in brainstem level of autistic children: A Review Study
Aims: Autism is a pervasive developmental disorder. Deficit in sensory functions is one of the characteristics of people with autism, and usually these people show abnormality in processing and correct interpretation of auditory information. Also people with Autism show problems in communicating with others. This review article deals with the accurate understanding of Auditory processing skills...
