Neuronal transmission mechanisms
Several techniques were used to study the morphology of the salivary apparatus of the cockroach, Nauphoeta cinevea. A general survey of the ultrastructure was made. The acinar cells were of two distinct types: peripheral and central cells. The ducts that these cells give rise to could be classified …

Microtubule Dynamics in Neuronal Morphogenesis
… (MTOCs) in neurons are not required as in non-neuronal cells. Assembly of microtubules within neurons is a major factor that affects neuronal morphology, and is regulated by tubulin availability and other nucleating factors. Maintenance of microtubules is determined in large part by …

Endolysosomal Function in Neuronal Maintenance
The file named "JIN-DISSERTATION-2018.pdf" is the primary dissertation file. All other files ("*.mp4") are supplemental files and may be viewed individually.

Memristive Devices For Neuronal Systems
The present post-doctoral thesis covers 14 original publications, which result from my work as research assistant between 2011 and 2015 at the Institute of electrical engineering at the technical faculty of the Christian-Albrecht university at Kiel. During this time my research work was strongly …

Feedback for neuronal system identification
… a fading memory. Non-equilibrium systems such as neuronal and chaotic models lack a fading memory. Their identification is challenging, in particular in the presence of input noise. In this thesis, we propose a methodology based on the prediction-error method for the identification of neuronal …

Sparse Expansion and Neuronal Disentanglement
We show how to improve the inference efficiency of an LLM by expanding it into a mixture of sparse experts, where each expert is a copy of the same weights and one-shot pruned for a specific cluster of input values. We call this approach Sparse Expansion. We show that for models like Llama 2 7B, as …

Neuronal and Electrophysiological Markers of Glioma
… based on three primary outcome measures, i.e., neuronal, electrophysiological and genetic/molecular features for distinguishing infiltrated and non-infiltrated zones within specifically peritumoral tissue (PT) and, more extensively, across the radiologically-defined boundaries of healthy, …

Studies of plasticity after neuronal injury
… to the spinal cord after central or peripheral neuronal injury, leading to the promotion of plasticity and functional repair. The development of a novel tool for visualising synapses is also described, presenting a novel opportunity for the study of plasticity after neuronal injury.

Regulation of Neuronal Polarity by Wnt Signaling
Wnts are highly conserved secreted glycoproteins that function in many developmental processes. Cell surface receptors, including the Frizzleds (Fz), ROR, and RYK families of proteins, bind Wnts to activate a number of downstream pathways. Wnts act redundantly to regulate the anteroposterior …

Visualization and Analysis Tools for Neuronal Tissue
The complex nature of neuronal cellular and circuit structure poses challenges for understanding tissue organization. New techniques in electron microscopy allow for large datasets to be acquired from serial sections of neuronal tissue. These techniques reveal all cells in an unbiased fashion, so …

Transcriptional Mechanisms Underlying Neuronal Activity-Dependent Plasticity
Pages 1-110 are misnumbered as pages 2-111.

Restoring bladder function by promoting neuronal regeneration
… work reporting the influence of artemin on neuronal RhoA activity suggests that artemin encourages regeneration across the DREZ by ramping up the intrinsic regenerative capacity of injured afferents to overcome the inhibitory barrier rather than breaking the barrier down.

Miniaturized Fluorescence Biosensor for Studying Neuronal Events
… under physiological conditions, conditions of neuronal injury and stress and acidic cortical spreading depression during stroke like conditions.

Cerebellar Coordination of Neuronal and Behavioral Rhythms
… cognitive and affective behaviors. Though the neuronal mechanism for the role of the cerebellum in cognition is still unclear, there is a consensus that it involves cerebellar interactions with the cerebral cortex. Recent studies suggest that the cerebellum monitors, and possibly coordinates, …

The effects of hyperglycaemia on neuronal mitochondria
… software to evaluate the proposed hypothesis. Neuronal cells were grown in high glucose (25 mM) or low glucose (1 mM) concentration and analysed for various parameters of mitochondrial characteristics.;When mitochondria are exposed to various concentrations of glucose, it provides more insights …

A quantitative study of neuronal calcium signaling
… as a second messenger responsible for modulating neuronal excitability in many ways including the mediation of gene transcription in the cell and the sensitivity of the cell to further stimulus. I propose a means of determining calcium conductance density of the cell membrane from intracellular …

ATP, TRP channels and airway neuronal sensitisation
… cells (PBECS) and an in-Vitro human sensory neuronal model differentiated from human dental pulp stem cells termed peripheral neuronal equivalents (PNEs). TRP channels are thought to play a role in the neuronal hyperresponsiveness responsible for chronic cough. Little is know regarding the …

Roles of gap junctions in neuronal networks
… the roles of gap junctions in the dynamics of neuronal networks in three distinct problems. First, we study the circumstances under which a network of excitable cells coupled by gap junctions exhibits sustained activity. We investigate how network connectivity and refractory length affect the …
