Human cortical dynamics during full-body heading changes.

Sci Rep 2021 Sep 14;11(1):18186. Epub 2021 Sep 14.

Institute of Psychology and Ergonomics, Technische Universität Berlin, Berlin, Germany.

The retrosplenial complex (RSC) plays a crucial role in spatial orientation by computing heading direction and translating between distinct spatial reference frames based on multi-sensory information. While invasive studies allow investigating heading computation in moving animals, established non-invasive analyses of human brain dynamics are restricted to stationary setups. To investigate the role of the RSC in heading computation of actively moving humans, we used a Mobile Brain/Body Imaging approach synchronizing electroencephalography with motion capture and virtual reality.

Gain from genomic selection for a selection index in two-row spring barley.

Plant Genome 2021 Sep 5:e20138. Epub 2021 Sep 5.

Plant Breeding and Genetics Section, School of Integrative Plant Sciences, Cornell University, Ithaca, NY, 14853, USA.

New breeding programs are faced with many challenges including evaluation of unknown germplasm, initiation of breeding populations that will satisfy short- and long-term breeding goals, and implementation of efficient phenotyping strategies for multiple traits. Genomic selection (GS) is a potentially valuable tool for recently established breeding programs to quickly accelerate genetic gain. Genomic selection on selection index (SI) values may increase gain over phenotypic selection but empirical studies remain limited. Read More

Quantitative assessment of the effects of biochar amendment on photosynthetic carbon assimilation and dynamics in a rice-soil system.

New Phytol 2021 Jul 29. Epub 2021 Jul 29.

Institute of Resource, Ecosystem and Environment of Agriculture, Nanjing Agricultural University, Nanjing, 210095, China.

Biochar amendment has been proposed as a promising means to increase carbon (C) sequestration and simultaneously benefit plant productivity. However, quantifying the assimilation and dynamics of photosynthetic C in plant-soil systems under biochar addition remains elusive. This study established two experimental factors involving biochar addition and nitrogen (N) fertilization to quantitatively assess the effect of biochar on photosynthetic C fate in a rice plant-soil system.

Cesk Patol 2021 ;57(2):113-119

This article focuses on the biography of the famous Czech pathologist Dušan Lambl (1824-95), especially during his period of life in Kharkiv, Sloboda Ukraine (part of the Russian Empire). At the end of the 1850s, pursued by the authorities of the Austrian Empire as a politically compromised person (being a Czech patriot and slavophile, he took an active part in the so-called Spring of Nations in 1848), Dušan Lambl was forced to seek refuge in the Russian Empire. He put forward his candidacy for the post of professor in the department of anatomy at the School of Medicine of Kharkiv University and was selected for this position. Read More

Gonda Multidisciplinary Brain Research Center, Bar Ilan University, Ramat Gan 5290002, Israel.

Parkinson's disease is prototypically a movement disorder. Although perceptual and motor functions are highly interdependent, much less is known about perceptual deficits in Parkinson's disease, which are less observable by nature, and might go unnoticed if not tested directly. It is therefore imperative to seek and identify these, to fully understand the challenges facing patients with Parkinson's disease. Read More
