The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.
Chronic pain distorts intensity coding in the anterior cingulate cortex to give rise to generalized anatomically nonspecific enhancement in pain aversion.
Alterations to brain network communication leading to a progressive loss in descending inhibitory modulation of the spinal cord is a key determinate of pain state development following peripheral nerve injury.
No single molecular change is uniquely necessary to cause neuropathic changes in primary afferent excitability; multiple different changes are sufficient.
A single-trial whole-brain analysis of three cognitive strategies to attenuate pain shows that a more effective pain attenuation is associated with increased functional connectivity across the entire brain.
Cognitive effort is aversive and people will accept physical pain to avoid it, but this avoidance does not appear to share the same fundamental characteristics of pain avoidance.
Machine learning analyses reveal that the observation of acute pain inflictions and facial expressions of pain evoke shared pain-specific neural representations.
A combination of human imaging and brain stimulation techniques show that the somatosensory cortex is essential to prosocial decision making, by transforming observed pain in accurate perception of others' distress.
Bigger bumblebee eyes have better vision, yet their field of view, sensitivity, and resolution do not all simply scale up with eye size, being improved locally instead.
