Projections of pyramidal tract cells to alpha‐motoneurones innervating hind‐limb muscles in the monkey

, 1975
1. We have investigated the spatial organization of monosynaptic corticospinal projections to hind‐limb motoneurones, using near threshold stimulation of the surface of the precentral gyrus to activate pyramidal tract (PT) cells and intracellular ...

Morphological features of large layer V pyramidal neurons in cortical motor-related areas of macaque monkeys: analysis of basal dendrites

Scientific Reports, 2021
In primates, large layer V pyramidal neurons located in the frontal motor-related areas send a variety of motor commands to the spinal cord, giving rise to the corticospinal tract, for execution of skilled motor behavior.

A mouse model of mechanical stress injury to the basal ganglia using thermosensitive PNIPAM hydrogel for intracerebral hemorrhage research

Animal Models and Experimental Medicine, EarlyView.
In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

Speech Biomarkers for Quantifying Effects of Subthalamic Deep Brain Stimulation in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective Dysarthria is one of the most common and disabling side effects of subthalamic nucleus deep brain stimulation (STN‐DBS) in Parkinson's disease (PD). Stimulation often exacerbates speech dysfunction beyond the effects of PD progression, likely because of current spread to structures surrounding the STN.

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

成人缺血性卒中后锥体束急性沃勒变性1例报道 A Case Report of Acute Wallerian Degeneration of Pyramidal Tract after Adult Ischemic Stroke

Zhongguo cuzhong zazhi
缺血性卒中后沿同侧锥体束的DWI高信号是沃勒变性（Wallerian degeneration，WD）主要的影像学表现之一，但在临床上易被漏诊或误诊为新发梗死。本文报道了1例缺血性卒中患者发病2周后所发生的锥体束急性WD，分析其头颅核磁影像中DWI与弥散张量成像的变化，并通过纤维追踪技术重建锥体束模型，实现可视化分析，以期为疾病诊断提供新的思路与方法。 Abstract: Hyperintensity on DWI along the ipsilateral pyramidal tract ...

Comparison of parameter threshold combinations for diffusion tensor tractography in chronic stroke patients and healthy subjects. [PDF]

PLoS ONE, 2014
BACKGROUND: Although quantitative evaluation of diffusion tensor imaging (DTI) data seemed to be extremely important for clinical research its application is under debate. Besides fractional anisotropy (FA) the quantitative comparison between hemispheres
