Parkinson's disease-like burst firing activity in subthalamic nucleus induced by AAV-α-synuclein is normalized by LRRK2 modulation

Parkinson's disease (PD) affects motor function through degenerative processes and synaptic transmission impairments in the basal ganglia. None of the treatments available delays or stops the progression of the disease. While α-synuclein pathological accumulation represents a hallmark of the disease in its idiopathic form, leucine rich repeat kinase 2 (LRRK2) is genetically associated with familia

Nociceptive inhibition of withdrawal reflex responses increases over time in spinalized rats

Time-dependent changes of nociceptive inhibition of hindlimb withdrawal reflex (WR) pathways were investigated in acute decerebrate spinal rats. Electromyographic recordings of WR of peroneus longus and extensor digitorum longus muscles were made. For each muscle, both short and long latency WR evoked by subcutaneous electrical stimulation and WR evoked by noxious pinch could be inhibited by noxio

Characteristics of postischemic seizures in hyperglycemic rats

Normoglycemic animals subjected to 10-20 min of transient ischemia survive without major neurological symptoms, but incur delayed neuronal damage selectively affecting vulnerable neuronal populations. If the animals are hyperglycemic before ischemia is induced, cell damage develops more rapidly, and postischemic seizures appear after a delay of 18-24 h. This study was designed to assess whether th

Generating Diffusion MRI Scalar Maps from T1 Weighted Images Using Generative Adversarial Networks

Diffusion magnetic resonance imaging (diffusion MRI) is a non-invasive microstructure assessment technique. Scalar measures, such as FA (fractional anisotropy) and MD (mean diffusivity), quantifying micro-structural tissue properties can be obtained using diffusion models and data processing pipelines. However, it is costly and time consuming to collect high quality diffusion data. Here, we theref

Fracture mechanics for membranes : The 15th European Conference of Fracture (ECF15)

During fracture of membranes loading often produces buckles above and below the crack surface. This changes the stress state surrounding the crack-tip and stresses in the neighbourhood of the crack-tip posses a weaker singularity than r-1/2. As a result, fracture occurs when the crack-tip stress distribution is different as compared with that when buckling is artificially prevented. Therefore the During fracture of membranes loading often produces buckles above and below the cracksurface.

Ecological Consequences of Animal Migration : Prey Partial Migration Affects Predator Ecology and Prey Communities

Patterns of animal migration and the ecological forces that shape them have been studied for centuries. Yet ecological impacts caused by the migration, such as altered predator–prey interactions and effects on community structure, remain poorly understood. This is to a large extent due to the scarcity of naturally replicated migration systems with negative controls, that is, ecosystems without mig

Finding the embedding dimension and variable dependencies in time series

We present a general method, the δ-test, which establishes functional dependencies given a sequence of measurements. The approach is based on calculating conditional probabilities from vector component distances. Imposing the requirement of continuity of the underlying function, the obtained values of the conditional probabilities carry information on the embedding dimension and variable dependenc
