Brain-to-gut trafficking of alpha-Synuclein by CD11c+ cells in a mouse model of Parkinson’s disease.

McFleder RL, Makhotkina A, Groh J, Keber U, Imdahl F, Peña Mosca J, Peteranderl A, Wu J, Tabuchi S, Hoffmann J, Karl AK, Pagenstecher A, Vogel J, Beilhack A, Koprich JB, Brotchie JM, Saliba AE, Volkmann J, Ip CW.

One trigger of the immune system in PD is aggregation of the pre-synaptic protein, α-synuclein (αSyn). Understanding the mechanism of propagation of αSyn aggregates is essential to developing disease-modifying therapeutics.

Optimization of data pre-processing methods for time-series classification of electroencephalography data.

Anders C, Curio G, Arnrich B, Waterstraat G.

Here, the influence of spatial filter optimization methods and non-linear data transformation on time-series classification performance is analyzed by the example of high-frequency somatosensory evoked responses.

Neurophysiological mechanisms of deep brain stimulation across spatiotemporal resolutions

Neumann WJ, Steiner LA, Milosevic L

In this Update we aim to produce an integrative account of complementary instead of mutually exclusive neurophysiological effects to derive a generalizable concept of the mechanisms of deep brain stimulation.

Dopaminergic Input Regulates the Sensitivity of Indirect Pathway Striatal Spiny Neurons to Brain-Derived Neurotrophic Factor

Ayon-Olivas M, Wolf D, Andreska T, Granado N, Lüningschrör P, Ip CW, Moratalla R, Sendtner M.

In this study, we showed that the activation of DRD2 in cultured striatal indirect pathway spiny projection neurons (iSPNs) and cholinergic interneurons causes the retraction of TrkB from the plasma membrane. This provides an explanation for the opposing synaptic plasticity changes observed upon DRD1 or DRD2 stimulation.

Local Field Potentials Predict Motor Performance in Deep Brain Stimulation for Parkinson’s Disease.

Busch JL, Kaplan J, Bahners BH, Roediger J, Faust K, Schneider GH, Florin E, Schnitzler A, Krause P, Kühn AA.

Using novel sensing-enabled neurostimulators, we investigated local field potentials (LFPs) and their modulation by DBS to assess whether electrophysiological biomarkers may facilitate clinical programming in chronically implanted patients.

Prediction of Stroke Outcome in Mice Based on Noninvasive MRI and Behavioral Testing.

Knab F, Koch SP, Major S, Farr TD, Mueller S, Euskirchen P, Eggers M, Kuffner MTC, Walter J, Berchtold D, Knauss S, Dreier JP, Meisel A, Endres M, Dirnagl U, Wenger N, Hoffmann CJ, Boehm-Sturm P*, Harms C*.

Systematic analysis of stroke outcome predictors in mice is lacking. We developed a tool to predict late pellet reaching performance based on early stroke localization in a diverse cohort of 215 mice.
