Objectives. Grey matter (GM) involvement is clinically relevant in multiple sclerosis (MS). Using source-based morphometry (SBM), we characterized GM atrophy and its 1-year evolution across different MS phenotypes. Methods. Clinical and MRI data were obtained at 8 European sites from 170 healthy controls (HCs) and 398 MS patients (34 clinically isolated syndromes [CIS], 226 relapsing-remitting [RR], 95 secondary progressive [SP] and 43 primary progressive [PP] MS). Fifty-seven HC and 144 MS underwent 1-year follow-up. Baseline...

The evolution of sexual signaling is linked to odorant receptor tuning in perfume-collecting orchid bees

Philipp Brand, Ismael A. Hinojosa-Diaz, Ricardo Ayala, Michael Daigle, Carmen L. Yurrita Obiols, Thomas Eltz & Santiago Ramirez
Sexual signaling is an important reproductive barrier known to evolve early during the formation of new species, but the genetic mechanisms that facilitate the divergence of sexual signals remain elusive. Here we isolate a gene linked to the rapid evolution of a signaling trait in a pair of nascent neotropical orchid bee lineages, Euglossa dilemma and E. viridissima. Male orchid bees acquire chemical compounds from their environment to concoct species-specific perfumes to later expose during...

Separable gain control of ongoing and evoked activity in the visual cortex by serotonergic input

Zohre Azimi, Ruxandra Barzan, Katharina Spoida, Tatjana Surdin, Patric Wollenweber, Melanie D. Mark, Stefan Herlitze & Dirk Jancke
Controlling gain of cortical activity is essential to modulate weights between internal ongoing communication and external sensory drive. Here, we show that serotonergic input has separable suppressive effects on the gain of ongoing and evoked visual activity. We combined optogenetic stimulation of the dorsal raphe nucleus (DRN) with wide-field calcium imaging, extracellular recordings, and iontophoresis of serotonin (5-HT) receptor antagonists in the mouse primary visual cortex. 5-HT1A receptors promote divisive suppression of spontaneous activity, while...

Data from: Biocultural approaches to sustainability: a systematic review of the scientific literature

Current sustainability challenges demand approaches that acknowledge a plurality of human-nature interactions and worldviews, for which biocultural approaches are considered appropriate and timely. This systematic review analyses the application of biocultural approaches to sustainability in scientific journal articles published between 1990 and 2018 through a mixed methods approach combining qualitative content analysis and quantitative multivariate methods. The study identifies seven distinct biocultural lenses, i.e. different ways of understanding and applying biocultural approaches, which to different...

Selinunt, Italien. Selinunt. Die Arbeiten des Jahres 2019

Ortwin Dally, Jon Albers, Heike Bücherl, Sophie Helas, Agnes Henning, Frédéric Mège, Arnaud Coutelas, Alf Lindroos & Jesper Olsen
The report contains the results of various research and excavation activities of the DAI Rome and its cooperation partners in Selinunt from the year 2019. The third and final campaign took place in the Agora, work continued on temples A and O, floor examinations were carried out in various houses on the Acropolis, a new DFG project was started in the east port, and in the Baglio Florio of the Parco Archeologico di Selinunte at...
