Large Animal Model for Development of Functional
· The opening on the lower border of the lamina was extended using a 3 mm Kerrison rongeur. This decreased the risk of inadvertent injury to the dura mater during electrode insertion. The ligamentum flavum was incised to allow access to the dural sac.
A new long-spined dinosaur from Patagonia sheds light on
· More than eighty years later, the discovery of a new, rather complete, dicraeosaurid skeleton from the Early Cretaceous of South America, Amargasaurus cazaui 3, …
A New Titanosaur Sauropod Dinosaur from the Upper
A new sauropod titanosaur from the Upper Cretaceous Anacleto Formation is described. Narambuenatitan palomoi gen. et sp. nov., is diagnosed by cranial and axial autapomorphies.
The functional organisation of glia in the adult brain of
The functions of glia in the adult vary depending upon their sub-type and location in the brain. The task of annotating glia is essentially complete only for the glia of the fly's lamina, which .
oldest cynodont: new clues on the origin and early
· The new cynodont specimen was recovered from a 0.25-m-thick lens of fissile, dark purple, mudstone on a parting between two 1-m-thick beds of massive grey siltstone with purple mottles. The massive siltstones contain scattered oblate pedogenic carbonate nodules and are interpreted as proximal floodplain deposits laid down at the base of the .
Non-invasive magnetic resonance imaging assessment of
· A non-invasive cine magnetic resonance imaging (MRI) technique was developed to allow, for the first time, detection and characterization of chronic changes in myocardial tissue volume and the effects upon these of treatment by the angiotensin-converting enzyme (ACE) inhibitor captopril in streptozotocin (STZ)-diabetic male Wistar rats.

Auditory midbrain implant: Research and development
· This type of enhanced activity cannot be simply achieved by activating more sites across different frequency laminae but requires activation of multiple sites within the same lamina (Straka et al., 2013). Therefore, stimulating at least two sites along a lamina may restore short-term integration and could improve hearing performance.
Neuropathology of Animal Prion Diseases - Abstract
According to the data from these studies, the PrP Sc distribution was limited to the brain in these natural cases, but experimental studies to better characterize the C-type BSE phenotype in the event that it is transmitted to sheep and goats have shown that both species are readily infected with the agent of C-type BSE and that lesion profile .

Finally, a new type of neuron, referred to as the adendritic neuron has been found to participate in the VC to DC projection (Friedland et al., 2003). The deepest layer of the DC contains two size categories of non-frequency specific cells, the giant cells which project to the contralateral inferior colliculus ( Malmierca et al. , 2005b ) and .
Dinosaur paleohistology: review, trends and new avenues
In the mid-19th century, the discovery that bone microstructure in fossils could be preserved with fidelity provided a new avenue for understanding the evolution, function, and physiology of long extinct organisms. This resulted in the establishment of paleohistology as a subdiscipline of vertebrate paleontology, which has contributed greatly to our current understanding of dinosaurs as living .
Brain Tissue Responses to Neural Implants Impact Signal
Implantable biosensors are valuable scientific tools for basic neuroscience research and clinical applications. Neurotechnologies provide direct readouts of neurological signal and neurochemical processes. These tools are generally most valuable when performance capacities extend over months and years to facilitate the study of memory, plasticity, and behavior or to monitor patients .
Distribution of 5-HT receptors in the central nervous
· Almost 10 years have passed since we wrote the review on the “Distribution of 5-HT receptors in the central nervous system” in this series (Mengod, Cortés, Vilaró, & Hoyer, 2010).The number of 5-HT receptors remains the same: 14 receptor subtypes grouped in seven families. New findings are related to the identification of the phenotype of the cells expressing 5-HT receptors and …
Hippocampus - ScienceDirect
· The principal cell type of the dentate gyrus is the granule cell. Estimates of the total number of granule cells in mice indicate that approximately 390,000 are present in each of the two dentates (Stanfield and Cowan, 1979).In mice, as in the rat, each granule cell is closely apposed to other granule cells, they lack basal dendrites and the conical shaped apical dendritic tree emerges from .

Physiological and Pathological Roles of Cdk5: Potential
Cyclin-dependent kinase 5 (Cdk5) is a proline-directed serine (ser)/threonine (Thr) kinase that has been demonstrated to be one of the most functionally diverse kinases within neurons. Cdk5 is regulated via binding with its neuron-specific regulatory subunits, p35 or p39. Cdk5–p35 activity is critical for a variety of developmental and cellular processes in the brain, including neuron .
