Space–time shape uncertainties in the forward and inverse problem of electrocardiography

Gander, Lia ; Krause, Rolf ; Multerer, Michael ; Pezzuto, Simone

In: International journal for numerical methods in biomedical engineering, 2021, vol. 37, no. 10, p. 23

In electrocardiography, the “classic” inverse problem is the reconstruction of electric potentials at a surface enclosing the heart from remote recordings at the body surface and an accurate description of the anatomy. The latter being affected by noise and obtained with limited resolution due to clinical constraints, a possibly large uncertainty may be perpetuated in the inverse ...

Identification of avoidance genes through neural pathway-specific forward optogenetics

Marques, Filipe ; Saro, Gabriella ; Lia, Andrei-Stefan ; Poole, Richard J. ; Falquet, Laurent ; Glauser, Dominique A.

In: PLOS Genetics, 2019, vol. 15, no. 12, p. e1008509

Understanding how the nervous system bridges sensation and behavior requires the elucidation of complex neural and molecular networks. Forward genetic approaches, such as screens conducted in C. elegans, have successfully identified genes required to process natural sensory stimuli. However, functional redundancy within the underlying neural circuits, which are often organized with multiple...

Role of the thalamus in basal forebrain regulation of neural activity in the primary auditory cortex

Azimi, Hamid ; Klaassen, Arndt-Lukas ; Thomas, Kevin ; Harvey, Michael A. ; Rainer, Gregor

In: Cerebral Cortex, 2020, vol. 30, no. 8, p. 4481–4495

Many studies have implicated the basal forebrain (BF) as a potent regulator of sensory encoding even at the earliest stages of or cortical processing. The source of this regulation involves the well-documented corticopetal cholinergic projections from BF to primary cortical areas. However, the BF also projects to subcortical structures, including the thalamic reticular nucleus (TRN), which...

3D models related to the publication: New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of the early Rhinocerotidae (Perissodactyla)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: MorphoMuseuM, 2020, vol. 6, no. 3, p. e116

The present 3D Dataset contains two 3D models described in Tissier et al. (https://doi.org/10.1098/rsos.200633): the only known complete mandible of the early-branching rhinocerotoid Epiaceratherium magnum Uhlig, 1999, and a hypothetical reconstruction of the complete archetypic skull of Epiaceratherium Heissig, 1969, created by merging three cranial parts from three distinct Epiaceratherium...

A revision of the pelomedusoid turtle Jainemys pisdurensis from the Late Cretaceous (Maastrichtian) Lameta Formation of India

Joyce, Walter G. ; Bandyopadhyay, Saswati

In: PeerJ, 2020, vol. 8, p. e9330

Background: Jainemys pisdurensis comb. nov. is an extinct pleurodiran turtle from the Late Cretaceous (Maastrichtian) of India, previously referred to Carteremys and Shweboemys. The holotype, an eroded skull, had been collected near the village of Pisdura, south of Nagpur, in Maharashtra State, while all referred shell material originates from coeval sediments exposed at the nearby village of...

Anatomic analysis of the internal and external aspects of the pterion

Uz, Aysun ; Korkmaz, Ali Can ; Filgueira, Luis ; Guner, Mehmet Ali ; Tubbs, Richard Shane ; Demirciler, Ayse Karatas

In: World Neurosurgery, 2020, vol. 137, p. 84–88

Objective: The pterion is an H-shaped suture complex. This study's goal was to determine the location of its external and internal surfaces and extension and emphasize and discuss its surgical importance.Methods: Fifty dried adult human skulls were obtained from the Department of Anatomy. A 2-mm drill bit was placed externally over the pterion, and the pterion was drilled through the bone...
