The cerebellum has already been shown to participate in the navigation function. We propose here that this structure is involved in maintaining a sense of direction and location during self-motion by monitoring sensory information and interacting with navigation circuits to update the mental representation of space. To better understand the processing performed by the cerebellum in the navigati...

Background: A number of neuroimaging studies on human addicts have revealed that abuse of Methamphetamine (METH) can induce neurodegenerative changes in various brain regions like the cerebral cortex and cerebellum. Although the underlying mechanisms of METH-induced neurotoxicity have been studied, the cellular and molecular mechanisms of METH-induced neurotoxicity remain to be clarified. Previ...

BACKGROUND: Mongooses are small carnivores residing in different regions from Africa to southeast Asia. The Indian gray mongoose (Herpestes Edwardsii) is one of the mongoose species that is mostly found in southern Asia particularly India and the south of Iran. Anatomical studies on the animal's brain have always been of interest to the scientist due to its high importance in various branches o...

Does the cerebellum influence nonmotor behavior? Recent anatomical studies demonstrate that the output of the cerebellum targets multiple nonmotor areas in the prefrontal and posterior parietal cortex, as well as the cortical motor areas. The projections to different cortical areas originate from distinct output channels within the cerebellar nuclei. The cerebral cortical area that is the main ...

Cooperation in the cerebellum y crossing knockout mice deficient for two cell adhesion molecules, Sakurai et al. have obtained the first genetic evidence for the molecules' functional overlap, and have explained why earlier tissue culture results were not replicated in single knockout mice (page 1259). Sakurai and colleagues started by engineering mice deficient for NrCAM, which had only mild (...

An ectopic cerebellum, as in Chiari malformations and ectopic cerebellar dysplastic tissue, is a common finding; however, the presence of an organized ectopic cerebellum is exceedingly rare. We describe the MR imaging, surgical, and histologic appearance of an intraspinal ectopic cerebellum in an infant.

Abstract Studies have shown that the integrity of white matter tracts connecting different regions in left cerebral hemisphere is important for aphasia recovery after stroke. However, impact underlying structural connection between cortex and cerebellum post-stroke poorly understood. We studied microstructural corticocerebellar connections their role picture naming. Fifty-six patients with infa...

Background Lifestyle-related risk factors (e.g., smoking) and common health problems hypertension) have been found to be associated with brain atrophy. However, it is still not clear about their independent contribution atrophy, especially among the elderly normal cognition. Here, we aim identify of atrophy in cognitively elderly. Method We included 419 subjects cognition (Table 1) from ADNI da...

Introduction Deficit in Theory of Mind (ToM) is a core feature schizophrenia (SZ), while adverse childhood experiences (ACEs) can contribute to worsen ToM abilities through their effect on brain functioning, structure and connectivity. Objectives Here, we investigated the effects ACEs functional connectivity (FC) during an affective cognitive task (AToM, CToM) healthy control (HC) SZ, whether F...
