Once Thought To Support Neurons, Astrocytes Turn Out To Be in Charge | Quanta Magazine New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest that neuron-only brain models, such as connectomes, leave out a crucial la...

The brain is more than spiking neurons. Astrocytes, a large fraction of cells, propagate electrical influences without spiking. And cortical neurons spike only intermittently. Electrical signals are continuous and across all cells.

Hemispherotomy leads to persistent sleep-like slow waves in the isolated cortex of awake humans Hemispherotomy is a neurosurgical procedure for treating refractory epilepsy by disconnecting a significant portion of the cortex. This study shows that the isolated cortex exhibits EEG patterns resem...

Autoimmune encephalitis-associated epilepsy Nature Reviews Neurology, Published online: 02 May 2025; doi:10.1038/s41582-025-01089-4In this Perspective, the authors provide a detailed description of rare autoimmune encephalitic conditions that present with recurrent seizures that are resistant to immunotherapy, grouped under the term autoimmune encephalitis-associated epilepsy. The article considers the clinical characteristics and pathophysiological mechanisms of these conditions, alongside current knowledge of treatment and outcomes.
