Identity-Shifting Brain Cells

The electrical activity of a neuron is considered a fundamental feature of its identity. But new research reveals this attribute is not necessarily fixed, at least in murine cortical inhibitory interneurons. In a paper...

The Brain on Fear

Animals respond to fear in predictable ways. A mouse confronted with danger is likely to either freeze in place or run for its life. But how this primal response is elicited in the brain...

How a Memory Is Made

When a nasty taste makes the stomach turn, neurons in the brain’s insular cortex fire up to form a memory of the foul flavor. But only a subset of cells are involved in storing...

Turning Back the Brain’s Clock

The time window for the brain to develop optimal connections based on learning and experience is relatively short-lived, occurring prior to adulthood. But this neuroplasticity can be restarted in the visual cortex of adult...

From Yeast to Therapeutic?

Yeast has shown some promise as a model system to generate lead compounds that could have therapeutic potential for the cellular problems associated with neurodegenerative diseases. Along these lines, Tardiff et al.(p. 979, published online 24 October)...
