Dynamic Neural Representations: An Inferential Challenge for fMRI.

Summary of "Dynamic Neural Representations: An Inferential Challenge for fMRI."

Measures of brain activity with high temporal resolution have shown that the information represented in a single brain region undergoes dynamic changes on the scale of milliseconds. This dynamic process presents a unique inferential challenge to low temporal resolution neural measures, such as BOLD fMRI. Potential solutions for fMRI requiring further investigation and development are discussed.

Medical and Biotech [MESH] Definitions

Mechanism by which changes in neural activity are tightly associated with regional cortical HEMODYNAMICS and metabolism changes. The association is often inferred from NEUROIMAGING signals (e.g., fMRI; or NIR SPECTROSCOPY).

An early embryonic developmental process of CHORDATES that is characterized by morphogenic movements of ECTODERM resulting in the formation of the NEURAL PLATE; the NEURAL CREST; and the NEURAL TUBE. Improper closure of the NEURAL GROOVE results in congenital NEURAL TUBE DEFECTS.

The two longitudinal ridges along the PRIMITIVE STREAK appearing near the end of GASTRULATION during development of nervous system (NEURULATION). The ridges are formed by folding of NEURAL PLATE. Between the ridges is a neural groove which deepens as the fold become elevated. When the folds meet at midline, the groove becomes a closed tube, the NEURAL TUBE.

A tube of ectodermal tissue in an embryo that will give rise to the CENTRAL NERVOUS SYSTEM, including the SPINAL CORD and the BRAIN. Lumen within the neural tube is called neural canal which gives rise to the central canal of the spinal cord and the ventricles of the brain. For malformation of the neural tube, see NEURAL TUBE DEFECTS.

The region in the dorsal ECTODERM of a chordate embryo that gives rise to the future CENTRAL NERVOUS SYSTEM. Tissue in the neural plate is called the neuroectoderm, often used as a synonym of neural plate.
