Salk scientists explain how CBN protects the brain against aging and neurodegeneration

One in every 10 individuals above the age of 65 develops an age-related neurological disorder like Alzheimer's or Parkinson's, yet treatment options remain sparse for this population.

Study reveals neuronal mechanisms behind working memory

Cedars-Sinai investigators have discovered how brain cells responsible for working memory-;the type required to remember a phone number long enough to dial it-;coordinate intentional focus and short-term storage of information.

Tiam1 inhibition mitigates morphine tolerance and hyperalgesia in mouse model

Morphine and other opioids are vital to treat severe and chronic pain. However, they have two problems -; prolonged use creates morphine tolerance, where ever-increasing doses are needed for the same pain relief, and paradoxically, prolonged use also can create an extreme sensitivity to pain, called hyperalgesia.

NeuM technology revolutionizes neuron labeling for neurodegenerative disease research

Alzheimer's disease and Parkinson's disease, along with stroke, are among the top three neurodegenerative disorders, characterized by the malfunction and progressive degeneration of neurons, the nerve cells.

Mitochondrial fusion critical for adult neurogenesis and brain circuit refinement

Nerve cells (neurons) are amongst the most complex cell types in our body. They achieve this complexity during development by extending ramified branches called dendrites and axons and establishing thousands of synapses to form intricate networks.

Neuroscientists identify age-defying RNAs in the brain

Certain RNA molecules in the nerve cells in the brain last a life time without being renewed. Neuroscientists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now demonstrated that this is the case together with researchers from Germany, Austria and the USA.
