Parallels Between Unresponsive Honey Bees and Human Autism

Parallels Between Unresponsive Honey Bees and Human Autism | Neurosciences | Scoop.it
Researchers report genes implicated in human ASD are regulated differently in honeybees that are more unresponsive than their nest mates. The PNAS study provides insight into the genetic heritage shared across species and offers clues about the evolution of social behavior.

Frontiers | Effects of the Adult Attachment Projective Picture System on Oxytocin and Cortisol Blood Levels in Mothers | Frontiers in Human Neuroscience

Frontiers | Effects of the Adult Attachment Projective Picture System on Oxytocin and Cortisol Blood Levels in Mothers | Frontiers in Human Neuroscience | Neurosciences | Scoop.it
Oxytocin, a small neuropeptide of nine amino acids, has been characterized as the “hormone of affiliation” and is stimulated, for instance, in mothers when interacting with their offspring. Variations in maternal oxytocin levels were reported to predict differences in the quality of care provided by mothers. In this study, the Adult Attachment Projective Picture System (AAP) as a valid measure to assess attachment representations was used as an activating attachment-related stimulus. We investigated whether the AAP induces a release of oxytocin in mothers with a secure attachment representation and a stress-related cortisol response in mothers with an insecure attachment representation. Therefore, pre-post effects of AAP administration on plasma oxytocin and serum cortisol levels were investigated in n = 44 mothers 3 months after parturition. Oxytocin levels increased from pre to post by the significant majority of 73% participants (p = .004) and cortisol decreased by the significant majority of 73% participants (p = .004). Interestingly, no association between alterations in oxytocin and cortisol were found; this suggests taking a model of two independent processes into considerations. These results show that the AAP test procedure induces an oxytocin response. Concerning the results within the four AAP representation subgroups, our hypothesis of a particularly strong increase in oxytocin in secure mothers was not confirmed; however, in secure mothers we observed a particularly strong decrease in cortisol, consistent with our hypotheses. Effect sizes are reported, allowing the replication of results in a larger study with sufficient sample size to draw final conclusions with respect to differences in OT and cortisol alterations depending on attachment representation. When interpreting the results, one should keep in mind that this study investigated lactating mothers. Thus, the generalizability of results is limited and future studies should investigate non-lactating healthy females as well as males and include a control stimulus condition.

Frontiers | Aberrant corticostriatal functional circuits in adolescents with Internet addiction disorder | Frontiers in Human Neuroscience

Abnormal structure and function in the striatum and prefrontal cortex have been revealed in Internet addiction disorder (IAD). However, little is known about alterations of corticostriatal functional circuits in IAD. The aim of this study was to investigate the integrity of corticostriatal functional circuits and their relations to neuropsychological measures in IAD by resting-state functional connectivity. Fourteen IAD adolescents and 15 healthy controls underwent resting-state fMRI scans. Using 6 predefined bilateral striatal regions-of-interest, voxelwise correlation maps were computed and compared between groups. Relationships between alterations of corticostriatal connectivity and clinical measurements were examined in the IAD group. Compared to controls, IAD subjects exhibited reduced connectivity between the inferior ventral striatum and bilateral caudate head, subgenual anterior cingulate cortex (ACC), and posterior cingulate cortex, and between the superior ventral striatum and bilateral dorsal/rostral ACC, ventral anterior thalamus, and putamen/pallidum/insula/inferior frontal gyrus (IFG), and between the dorsal caudate and dorsal/rostral ACC, thalamus, and IFG, and between the left ventral rostral putamen and right IFG. IAD subjects also showed increased connectivity between the left dorsal caudal putamen and bilateral caudal cigulate motor area. Moreover, altered cotricostriatal functional circuits were significantly correlated with neuropsychological measures. This study directly provides evidence that IAD is associated with alterations of corticostriatal functional circuits involved in the affective and motivation processing, and cognitive control. These findings emphasize that functional connections in the corticostriatal circuits are modulated by affective/motivational/cognitive states and further suggest that IAD may have abnormalities of such modulation in this network.

Are Smart Drugs Really So Smart? | SciTech Connect | Neurosciences | Scoop.it
Obviously we can’t divine the future. But predicting the social side effects that safe, effective, and inexpensive cognitive enhancers are likely to have in competitive societies like ours seems like a no-brainer. Our bet is that it will result in an even more work-obsessed culture, and even less time than we currently have for other pursuits that enhance human life. Remember those predictions from the 1980s about how in the future we would all be working 15-hour weeks thanks to gains in efficiency afforded by technological advances? The reason that never happened is not because the technology failed to deliver those gains in efficiency. It’s because we chose to use that efficiency to do more work.
