Published in 2018 at "Biodiversity and Conservation"

DOI: 10.1007/s10531-018-01691-7

Abstract: To understand patterns of alpha, beta and gamma diversities in fragmented landscapes we need to explore the three scale components in relation to potential drivers in a scale-dependent manner. Often, the drivers themselves can be… read more here.

Published in 2017 at "Clinical Neurophysiology"

DOI: 10.1016/j.clinph.2017.06.147

Abstract: The pharmacotherapy of Parkinson’s disease (PD) is based on levodopa, and dopamine receptor agonists, such as apomorphine. Although both types of agents provide beneficial clinical effects on motor and non-motor symptoms in PD clinical efficiency… read more here.

Published in 2019 at "Neurobiology of Aging"

DOI: 10.1016/j.neurobiolaging.2019.02.009

Abstract: The 3xTg-AD mouse model reproduces the main features associated with the etiology of familial Alzheimer's disease (AD). To investigate whether these features imply functional cortical network alterations and their evolution with age, we studied spontaneous… read more here.

Published in 2017 at "Neuron"

DOI: 10.1016/j.neuron.2017.11.033

Abstract: Distinct subtypes of inhibitory interneuron are known to shape diverse rhythmic activities in the cortex, but how they interact to orchestrate specific band activity remains largely unknown. By recording optogenetically tagged interneurons of specific subtypes… read more here.

Published in 2022 at "Viruses"

DOI: 10.3390/v14050966

Abstract: SARS-CoV-2 variants, including B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), and B.1.617.2 (Delta) variants, have displayed increased transmissibility and, therefore, have been categorized as variants of concern (VOCs). The pervasiveness of VOCs suggests a high probability… read more here.
