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 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 2024 at "Scientific Reports"

DOI: 10.1038/s41598-024-57252-2

Abstract: Analysis of coupling between the phases and amplitudes of neural oscillations has gained increasing attention as an important mechanism for large-scale brain network dynamics. In Parkinson’s disease (PD), preliminary evidence indicates abnormal beta-phase coupling to… read more here.
