Whole-body somatotopic maps in the cerebellum revealed with 7T fMRI
2020年5月1日 · Using high spatial resolution fMRI data acquired at ultra-high field (7T), with special care taken to obtain sufficient B 1 over the entire cerebellum and a cerebellar surface reconstruction facilitating visual inspection of the results, we were able to precisely map the somatotopic representations of these five distal body parts on both ...
Whole-body somatotopic maps in the cerebellum revealed with 7T fMRI
2020年5月1日 · With this study, we were able to precisely define somatotopic maps in both anterior and posterior lobes of the cerebellum for five distal body parts. We demonstrated that both bilateral anterior and posterior lobes contain somatotopic gradients organized in a medio-posterior to latero-anterior fashion where the eyes, tongue, thumbs, little ...
An fMRI dataset for whole-body somatotopic mapping in humans …
2022年8月23日 · Here, we present public high-resolution fMRI data to map the somatotopic organization based on motor movements in a large cohort of healthy adults (N = 62).
Emergence of a brainstem somatosensory tonotopic map for
15 小时之前 · Lee et al. show that the development of the somatotopic map and the tonotopic map for substrate vibration is shaped by the intrinsic distribution of cutaneous end organs and selective dendritic ...
Sensorimotor mapping of the human cerebellum: fMRI evidence …
2001年4月17日 · In the upper representation, an intralimb somatotopy for the right elbow, wrist, and fingers was revealed. The maps seem to confirm earlier electrophysiological findings of sagittal zones in animals. They differ, however, from micromapping reports on fractured somatotopic maps in the cerebellar cortex of mammals.
A century of cerebellar somatotopy: a debated representation
2004年3月1日 · The existence of functional localization within the cerebellum was advanced exactly one century ago by both comparative anatomical and physiological studies. Here, we will discuss how models of...
Whole-body somatotopic maps in the cerebellum revealed with 7T fMRI
2020年2月1日 · The cerebellum is known to contain a double somatotopic body representation. While the anterior lobe body map has shown a robust somatotopic organization in previous fMRI studies, the...
The cerebellum is known to contain a double somatotopic body representation. While the anterior lobe body map has shown a robust somatotopic organization in previous fMRI studies, the
Topography of Cerebellar Deficits in Humans | The Cerebellum …
2011年1月15日 · Multiple somatotopic maps have been identified in the cerebellum . Functional neuroimaging studies have revealed a first body representation in the anterior lobe (lobules I–V) and a second in the inferior part of the posterior lobe (mainly lobules VIIB and VIII) [13–15].
Whole-body somatotopic maps in the cerebellum revealed with …
2020年2月11日 · High-resolution, B1-shimmed, functional magnetic resonance imaging at 7T is employed to investigate proprioceptive involvement of the cerebellum in humans and identifies distinct activation patterns for the two tasks within these cerebellar motor regions, which may reflect differing functional roles of these motor areas.
