Weekly Neuroscience Update

A new review of neurological symptoms of COVID-19 patients reveals the disease poses a global threat to the entire nervous system, reports a study in Annals of Neurology.

Researchers have combined tools from machine learning and neuroscience to discover that the brain uses a mathematical system to organize visual objects according to their principal components.

A new system for high-density EEG helps with the imaging of the origin and path of both normal and abnormal neural activity.

Brain function depends on inhibitory cells that balance or ‘brake’ excitation. These neurons allow the brain to process information and also prevent runaway seizures. A new study however, reports that in some critical structures of the developing brain, the inhibitory neurons cause excitation rather than suppression of brain activity. The findings, published in Science Advances, could have implications for the treatment of neonatal seizures.

New research shows changes in gut mucus may contribute to Alzheimer’s, Parkinson’s, and other neurological disorders.

Researchers have identified how specific genetic mutations cause ALS. The pathway, they believe, may also be responsible for the development of frontotemporal dementia.

Cancer itself, rather than chemotherapy alone, may contribute to the development of neuropathy some patients experience.

Finally this week, results from a new study suggest that whether certain genes are expressed — turned on or off– may play a role in susceptibility to post-traumatic stress disorder (PTSD).
