The Dangers of Cortical Brain Maps
Journal of Cognitive Neuroscience, 2023Abstract The parcellation of the primate cerebral cortex into numbered regions, based on cytoarchitecture, has greatly helped neuroscientists in our quest to understand how the brain implements cognition. Nonetheless, these maps provide an unnecessarily constraining view of how we should do functional neuroanatomy.

On the retino-cortical mapping
International Journal of Man-Machine Studies, 1983Abstract Based on Hubel & Wiesel's physiological findings on the projection from retina to cortex, a schematic model of that stage of visual processing is constructed and its properties investigated. The projection or mapping appears to carry out an automatic “normalization of description” for the same object independent of retinal image size.

Cortical Sulcal Maps in Autism
Cerebral Cortex, 2003This study presents the first three-dimensional mapping of cortical sulcal patterns in autism, a pervasive developmental disorder, the underlying neurobiology of which remains unknown. High-resolution T(1)-weighted MRI scans were acquired in 21 autistic (age 10.7 +/- 3.1 years) and 20 normal control (age 11.3 +/- 2.9) children and adolescents.

Dipolar estimates of the cortical map
2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014Various methods based on anatomical or mathematical models have been developed to estimate cortical potentials. Among them, the most popular are the surface Laplacians (SL) and the Electrical Source Imaging (ESI) approaches. In this paper, we develop an informed method named dipolar cortical mapping (DCM), aiming to find a balance between ESI methods ...

Metrics for Cortical Map Organization and Lateralization
Bulletin of Mathematical Biology, 1998Cerebral lateralization refers to the poorly understood fact that some functions are better controlled by one side of the brain than the other (e.g. handedness, language). Of particular concern here are the asymmetries apparent in cortical topographic maps that can be demonstrated electrophysiologically in mirror-image locations of the cerebral cortex.

Diffeomorphic cortical surface mapping and its comparison with spherical cortical mapping
The 2011 IEEE/ICME International Conference on Complex Medical Engineering, 2011In this paper, we introduced a multi-manifold large deformation diffeomorphic metric mapping (MM-LDDMM) algorithm that carried the cortical hemispheric surface and its sulcal and gyral curves simultaneously from one to the other through a flow of diffeomorphisms.

The Journal of the Acoustical Society of America, 1999
Tonotopy is a well-known property of the brain which consists of a linearly organized representation of the tonal frequencies on the auditory cortex. A similar organization for the rate of auditory events (tempo) is demonstrated. Subjects listened to isochronous, isotonic sequences of pure tones varying in tempo (100-, 200-, 250-, 300-, 400-, 800-, and

Mapping of cortical histogenesis in the ferret
Development, 1984ABSTRACT The columnar organization of forebrain cortical neuron production allows the neuroepithelium to be analysed in terms of a simple growth model. The pattern of neuron release within each column is repeated with great regularity across the surface of the developing cerebral hemisphere, resulting in the accumulation of cortical ...

A Guide for Cortical Electrical Stimulation Mapping
Journal of Clinical Neurophysiology, 2018Summary: Electrical stimulation mapping (ESM) of the brain remains a major procedure for guiding epilepsy and tumor surgeries. This article collates available experiences and data in ESM to develop a guide for conducting the procedure. There are many factors that influence the yield of ESM.

Cortical tonotopic map plasticity and behavior
Neuroscience & Biobehavioral Reviews, 2011Central topographic representations of sensory epithelia have a genetic basis, but are refined by patterns of afferent input and by behavioral demands. Here we review such experience-driven map development and plasticity, focusing on the auditory system, and giving particular consideration to its adaptive value and to the putative mechanisms involved ...
