Studying synapses in live human brains is crucial for understanding many psychiatric disorders. Now, using positron emission tomography of the brain of patients with psychiatric disorders, researchers from Japan have developed and used a novel technology to visualize the distribution of AMPA receptors, one of the most important molecules in synaptic transmission. Their efforts could lead to more accurate diagnosis and targeted treatments for diseases like schizophrenia, bipolar disorder, and autism spectrum disorder.
