A new deep learning algorithm is superior to human experts in distinguishing between retinal ganglion cells in healthy patients and in those with glaucoma. The AI system could potentially help improve the diagnosis of both eye and brain diseases.
At the site of injury, nerves release a protein called CXCL12 which attracts growing nerve fibers and keeps them trapped in place. This prevents the nerve fibers from growing in the correct direction to bridge the injury site.

Researchers have identified functional features that make human neurons unique.
Researchers have implicated alterations in the balance of two chloride ion channels in the cognitive deficits associated with schizophrenia. Inhibiting transporter activity with bumetanide reversed some of the cognitive symptoms in mouse models of the psychiatric disorder.
PsychLight, a newly developed genetically encoded fluorescent sensor, helped researchers identify a psychedelic compound that acts on beneficial neural pathways to treat psychiatric disorders without the hallucinogenic effect.
Researchers have identified regions within the DNA of neurons that accumulate single-strand breaks (SSBs). The SSB accumulation appears to be unique to neurons. The findings challenge previous thoughts on the cause of DNA damage and how it could impact neurodegenerative disorders.
Astrocytes influence how long, and how deeply, mice sleep, a new study reports.
