Within and Beyond the Visual Cortex: Brain Tumors Induce Highly Sensitive Plasticity of Visual Processing in Whole-Brain Neural Functional Networks.

Cereb Cortex 2022 Feb 1. Epub 2022 Feb 1.

Department of Clinical Neurolinguistic Research, Mental and Neurological Diseases Research Center, The Third Affiliated Hospital, Sun Yat-sen University, Guangzhou 510630, P.R. China.

Vision is a key source of information input for humans, which involves various cognitive functions and a great range of neural networks inside and beyond the visual cortex. There has been increasing observation that the cognitive outcomes after a brain lesion cannot be well predicted by the attributes of the lesion itself but are influenced by the functional network plasticity. However, the mechanisms of impaired or preserved visual cognition have not been probed from direct function-execution conditions and few works have observed it on whole-brain dynamic networks.

Early and Bi-hemispheric seizure onset in a rat glioblastoma Multiforme model.

Neurosci Lett 2022 01 15;766:136351. Epub 2021 Nov 15.

Department of Neurology, University of Michigan, Ann Arbor, MI, China. Electronic address:

GBM is the most life-threatening neurological disease with annual incidence of ∼ 5 cases per 100,000 people and a median survival of less than 15 months. Seizures are the first clinical symptoms in 40%-45% of patients with GBM and its epileptogenic mechanisms are poorly understood, largely due to the challenge to develop a clinically-relevant animal model and the unknown latent period. In this study, we used continuous video-EEG monitoring to detect the earliest interictal and ictal events in a CRISPR- IUE GBM rat model that shares pathological and clinical features with those observed in human patients.

Functional alterations in cortical processing of speech in glioma-infiltrated cortex.

Proc Natl Acad Sci U S A 2021 11;118(46)

Department of Neurological Surgery, University of California, San Francisco, CA, 94143;

Recent developments in the biology of malignant gliomas have demonstrated that glioma cells interact with neurons through both paracrine signaling and electrochemical synapses. Glioma-neuron interactions consequently modulate the excitability of local neuronal circuits, and it is unclear the extent to which glioma-infiltrated cortex can meaningfully participate in neural computations. For example, gliomas may result in a local disorganization of activity that impedes the transient synchronization of neural oscillations. Read More
