Ketamine’s Effects Diverge by Sex

Ketamine's effects on depression and pain, and its interaction with opioid pathways, significantly differ between sexes. In a detailed rat study, the team found that blocking opioid receptors nullified ketamine's impact only in males, suggesting a complex interplay between ketamine, opioid systems, and sex hormones.

Electrical Stimulation Enhances Hypnotizability

Researchers have found that targeted electrical stimulation of the brain can temporarily increase a person's hypnotizability, potentially allowing more individuals to benefit from hypnosis-based therapies for pain relief and other conditions. In a study involving participants with fibromyalgia, electrical stimulation delivered to the left dorsolateral prefrontal cortex boosted hypnotizability for about an hour.

Brain States Influence on Decision-Making

New study on mice decision-making reveals that choice is not a singular moment but a reflection of the brain's preexisting state. The research, using Buridan's Assay, suggests that the mice's brain constantly broadcasts its goal, even before options are available, with patterns of neuron activity predicting choice.
