Interrogation of Neuromedin U Receptor 2/Neuromedin U as a Novel Therapeutic Target for the Treatment of Obesity
… to treat obesity. The identification of key neural pathways that play a role in food consumption have helped highlight the Neuromedin U Receptor 2 (NMUR2) as a promising target that can regulate body weight and food intake. NMUR2 is activated by the endogenous ligand, Neuromedin U (NMU), …

Suppressing What Hurts: The Role of Prefrontal-Thalamic Pathways in Inhibitory Control of Intrusive Thoughts and Conditioned Fear
… suppression in humans; however, the precise neural pathway(s) remain unknown. Converging anatomical and functional evidence in rodents and more recently in primates suggests that the Nucleus Reuniens (NRe), a small but vital nucleus situated in the ventral midline of the thalamus plays an …

Response properties of neighboring neurons in the auditory midbrain
… ascending auditory pathway. Nearly all ascending neural pathways converge and synapse in the central nucleus of the inferior colliculus (ICC). Further, the anatomical arrangement of axons and neurons in the ICC suggests the existence of functional regions which may play a role in organizing …

Heartbeat rate modulation mediated by the ventral nerve cord in the honey bee, APIS MELLIFERA
… Modulation is considered to occur via either neural or neurohormonal mechanisms but there is little existing data of the type necessary for proving one mechanism or the other. Using the recording technique of impedance conversion, heartbeat patterns were established for intact Honey Bees …

Reduced Order Modeling of Flapping Wing Flight Dynamics
… computational resources in their specialized neural pathways to generate robust, agile performance. The flapping wing design is less studied, and the underlying physical principles are often more complex – non-linear time varying dynamics are dominated by forcing due to complex, unsteady …

Omni : visualizing and editing large-scale volume segmentations of neuronal tissue
… of the nervous system and enables them to trace neural pathways through these large images. By studying the structure of individual neurons and groups of neurons, researchers can approach a better understanding of neuron function and the development of the brain.

The spread of pathological assemblies in neurodegenerative disease
… are caused by the misfolding of specific neural proteins. However, it is not fully known how this misfolding results in neuronal dysfunction and death, nor why different diseases preferentially affect different regions of the brain. In recent years, there has been increasing evidence that …

Can long-term musculoskeletal, spinal pain improve with movement education using SEMG biofeedback?
… new movements, altering and training new neural pathways, and enabling greater muscular control. In addition, an improvement in muscular awareness from SEMG biofeedback correlates with improved back pain. Musculoskeletal pain is multifactorial. Pain can have multiple causes, including poor …

Measuring and Comparing the Diffusion Rate of Fluorescent-Lipophilic-Neurotracing Probes in Murine-Peripheral-Nerve Preparations
… dyes are used as probes to study the neural pathways that wire the brain. Since these dyes are able to define neuroanatomic connections through all stages of normal and mutant development, they are currently the most comprehensive method for neurotracing. In order to efficiently trace …

Novel Implementation of Additive Manufacturing to Visualize the Human Brain Connectome
… uses probabilistic mapping on an MRI to identify neural pathways and averages these identified connections from many MRI’s to create a standard atlas of the adult human brain.</p> <p>Currently AM files for 3D printing rely on a surface triangulation mesh to describe the model. This mesh consists …

Interazione dopamina-ossitocina nel controllo centrale della risposta erettile
… The results obtained suggest the existence of a neural circuit where dopaminergic and oxytocinergic neurons play a key role in the motivational/rewarding and consummatory aspects of male sexual behavior. When activated, this circuit facilitates not only the copulatory behavior through the …

A brain-machine interface for investigating neural representations of navigation in a virtual environment
Simultaneously recording behaviour and neural activity can only take researchers so far in understanding the function of different regions of the brain, and the neurons therein. Novel methods are required for probing further beyond standard correlational and knockout analysis. The activity of one …
