Direct pathway: Involves only one relay structure (GPi or SNr) between the striatum and thethalamusto activate the cortex. The direct pathway promotes action. • Indirect pathway: Involves multiple relay structures (GPe,STN, and GPi or SNr) between the striatum and the thalamus and provides li...
In discussing the basic principles of neuronal structure we are providing the background for discussing the development of connections between cells in the brain and for understanding information processing on the level of single cells. The neuron is the most complex and fascinating of all cells. ...
Methods: This paper introduces a new pipeline for reconstructing neuron anatomy structure from 3-D microscopy image stacks. This pipeline is initialized with a set of seeds that were detected by our proposed Sliding Volume Filter (SVF), given a non-circular cross-section of a neuron cell. Then...
Structure and distribution of dorsal unpaired median (DUM) neurones in the abdominal nerve cord of male and female locusts Dorsal unpaired median (DUM) neurones in insects have been shown to modulate the activity of both skeletal and visceral muscle. It has been suggested that ... H.-J.,Pf...
One possible explanation for why auxiliary learning is also helpful for the prediction of neuron boundaries is that the additional task incentivizes the network to consider higher-level features. Predicting LSDs is likely harder than boundaries, since additional local structure of the object has to ...
Transmission electron microscopy (TEM), wherein the ultrastructure can be imaged at the membrane level, cannot determine the whole structure, and analyze it quantitatively. Volume EM, such as focused ion beam/scanning electron microscopy (FIB/SEM), can be a powerful tool to explore the details ...
The blood–brain barrier (BBB) is a structure of tightly connected brain endothelial cells, pericytes, and astrocytes that protects the brain from harmful substances and ensures the passage of nutrients from circulation into the brain17,18. The BBB also regulates the entry of immune cells into th...
becoming less sensitive to light exposure, sedentary lifestyle, extended naps that may be contributing to a desensitisation of the 24-hour light-dark cycles and insomnia complaints (Martinez-Nicolas et al., 2018). Changes in sleep structure occur with ageing, particularly the prominent diminishing ...
