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 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.

Researchers have identified functional features that make human neurons unique.
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.
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.
