Seeing serotonin neurons in action

Feb. 9, 2011—Serotonin – a chemical that has roles in multiple brain functions, including mood, sleep and cognition – is manufactured by clusters of brainstem neurons gathered in the raphé nuclei. A reliable, non-invasive imaging method for assessing raphé neuron activity would be valuable for understanding serotonin signaling in depression and related conditions. Using functional magnetic resonance...

Paraplegia-causing proteins pair up

Feb. 4, 2011—Hereditary spastic paraplegia (HSP), a group of progressive neurodegenerative disorders that impairs the ability to walk, can be caused by mutations in more than 40 different genes. Despite this genetic heterogeneity, the pathologic features – degeneration of long axons in the spinal cord – are relatively uniform, suggesting that dysfunction of a common biochemical pathway...
