Analysis of worm neurons suggests how a single stimulus can trigger different responses

Analysis of worm neurons suggest how a single stimulus can trigger different responsesIn experiments, the state of a simple brain network determined the likelihood a worm would move toward a delicious smell or ignore it. Scaled up to account for the more nuanced behaviors of humans, the research may suggest ways in which our brains process competing motivations. More »

Atomic-level view provides new insight into translation of touch into nerve signals

Atomic-Level View Provides New Insight into Translation of Touch into Nerve SignalsAn ion channel responsible for dampening potentially painful sensations uses a never-before-seen mechanism to shut itself off: A lipid from the nearby cellular membrane protrudes into the channel, blocking it.

Newly discovered brain cells explain a prosocial effect of oxytocin

Newly discovered brain cells explain a prosocial effect of oxytocinWhen activated by the ‘love hormone’ oxytocin, a class of star-shaped neurons in the brain’s cortex encourages female mice to take an interest in males, but only when the females are in heat. More »

Genetically driven gut feelings help female flies choose a mate

Genetically driven gut feelings help female flies choose a mateResearchers at Rockefeller University have determined that the Abdominal-B (Abd-B) gene, previously known as the gene that sculpts the posterior parts of the developing fly, is also important for a complex courtship behavior, at least in the case of female flies.

Researchers profile active genes in neurons based on connections

140519_friedman_retrotrap1_thumbA new technique allows researchers to examine gene expression in neurons that send messages to a synapse. A test run examined dopamine neurons that project to the brain region known as the nucleus accumbens.
