Mental chronometry using latency-resolved functional MRI.
Vascular responses to neural activity are exploited as the basis of a number of brain imaging techniques. The vascular response is thought to be too slow to resolve the temporal sequence of events involved in cognitive tasks, and hence, imaging studies of mental chronometry have relied on techniques such as the evoked potential. Using rapid functional MRI (fMRI) of single trials of two simple b...
متن کاملTracking cognitive processes with functional MRI mental chronometry.
Functional magnetic resonance imaging (fMRI) is used widely to determine the spatial layout of brain activation associated with specific cognitive tasks at a spatial scale of millimeters. Recent methodological improvements have made it possible to determine the latency and temporal structure of the activation at a temporal scale of few hundreds of milliseconds. Despite the sluggishness of the h...
متن کاملFunctional MRI using super-resolved spatiotemporal encoding.
Recently, new ultrafast imaging sequences such as rapid acquisition by sequential excitation and refocusing (RASER) and hybrid spatiotemporal encoding (SPEN) magnetic resonance imaging (MRI) have been proposed, in which the phase encoding of conventional echo planar imaging (EPI) is replaced with a SPEN. In contrast to EPI, SPEN provides significantly higher immunity to frequency heterogeneitie...
متن کاملPsychometric G and mental chronometry.
open concepts that comprise all aspects of brain activity that result in some form of information processing, Two main aspects of these functions call for investigation: (1) the basic neural design features and operating principles of the brain that make these functions possible, and (2) the cause of individual biologically normal variation in the proficiency of performing these cognitive funct...
متن کاملAdvances in modern mental chronometry
Mental chronometry encompasses all aspects of time processing in the nervous system and constitutes a standard tool in many disciplines including theoretical and experimental psychology and human neuroscience. Mental chronometry has represented a fundamental approach to elucidate the time course of many cognitive phenomena and their underlying neural circuits over more than a century. Nowadays,...
