Cellular aging is linked to structural changes in the brain
A new study now shows that if telomeres change in their length, that change is also reflected in our brain structure.

Tracking Alzheimer's disease pathology in single neuronal cells
Researchers have developed a superior method to describe the very earliest effects that Alzheimer's Disease proteins have on the properties of brain cells.
Read moreInflammation amps up neurite growth, gene expression involved in heat, cold sensitivity
Inflammation increases neuronal activity, gene expression and sensory nerve (neurite) outgrowth in neurons involved in thermal — but not physical- sensations in mice.
Read moreNeurons' response to seizure-induced stress reduces seizure severity
In response to seizures, the endoplasmic reticulum (ER), a network of flattened tubes in the cell that packages and transports proteins, triggers a stress response that reduces brain activity and seizure severity. The new findings may have important implications for the development of new epilepsy therapies.
Read morePotential diagnostic tool, treatment for Parkinson's disease
Investigators have pinpointed a molecular defect that seems almost universal among patients with Parkinson's disease and those at a high risk of acquiring it.
Read moreHow neural circuits form in a developing embryo
A new imaging method follows young neurons in a developing embryo as they progress from a messy jumble of cells into a coordinated control center. The approach lets scientists track development and emerging cell function simultaneously across entire circuits.
Read moreHow neural circuits drive hungry individuals to peak performance
Success is no accident: To reach your goal you need perseverance. But where does the motivation come from? Scientists have now identified the neural circuit in the brain of fruit flies which makes them perform at their best when searching for food.
Read moreHow time affects the fate of stem cells
Scientists have discovered how temporal fluctuations in the levels of two transcription factors can push embryonic stems cells into becoming different cell types.
Read moreTechnique can image individual proteins within synapses
Researchers have devised a new way to rapidly image synaptic proteins at high resolution. Using fluorescent nucleic acid probes, they can label and image as many as 12 different proteins in neuronal samples containing thousands of synapses.

Epileptic seizures can probably not be predicted by changes in brain wave patterns that were previously assumed to be characteristic precursors.
