Abstract:

<p> A neuron’s unique physiological waveform arises from its palette of ion channels and receptors, as superimposed on its geometrical structure. The crustacean stomatogastric ganglion (STG), a small rhythmic motor circuit, exhibits fourteen identified neuron types with highly-conserved physiological waveforms and complex morphologies. In this thesis, I examine how morphology shapes neuronal physiology in the STG. Using high-resolution neuronal reconstructions and a suite of computational tools, I quantify numerous morphological features of four STG neuron types. This work revealed remar

Abstract:

The advent of super-resolution microscopy, also called nanoscopy, allowed a substantial improvement of spatial resolution, opening the door for the observation of biological structures beyond the diffraction limit impossible with conventional light microscopy. Among the super-resolution techniques, single-molecule localization microscopies have proven to be a powerful tool to address many biological issues, since they provide an imaging resolution of the order of tens of nanometers and the possibility to perform quantitative measurements. Neuroscience has been one of the fields in biology to

Abstract:

Connexins are transmembrane proteins that form hemichannels allowing the exchange of molecules between the extracellular space and the cell interior. Two hemichannels from adjacent cells dock and form a continuous gap junction pore, thereby permitting direct intercellular communication. Connexin 36 (Cx36), expressed primarily in neurons, is involved in the synchronous activity of neurons and may play a role in aberrant synchronous firing, as seen in seizures. To understand the reciprocal interactions between Cx36 and seizure-like neural activity, we examined three questions: a) does Cx36 defic

Introduction Les gliomes de bas grade sont des tumeurs cérébrales de progression lente qui affectent l’adulte jeune. Ce mode d’évolution laisse le temps aux réseaux neuraux de se réorganiser de façon massive ce qui permet d’expliquer pourquoi les patients ne présentent habituellement aucun déficit neurologique au diagnostic bien que la tumeur concerne des zones dites «éloquentes». Ces lésions sont donc un sujet d’étude particulièrement intéressant dans la compréhension des mécanismes de plasticité cérébrale.Ces patients bénéficient, comme traitement optimal, d’une chirurgie en condition éveill

Detection of chemical stimuli from the external environment is performed by all living organisms. Of all senses, the chemical sense is the evolutionary oldest.

Due to their highly specialized ability of detecting air-born molecules over long distances, plus an accessible nervous system, noctuid moths have served as favorable model organisms for exploring basic neural principles underlying chemosensory information processing.

These correlations in “resting state” fMRI have been strongly linked to behavior and disease.

Most animal species strongly depend on their sense of vision. The ability to perceive and discriminate chromatic signals is very useful for object detection and identification in the natural environment. Animals with a larval stage are generally characterized by a huge investment of energy in the rapid development of a complex retina associated with downstream visual circuits, which will improve the larva’s chances of survival with sensorial cues fundamental for both predator escape and prey capture. Indeed, the environmental distribution of radiance, covering a wide range of wavelengths, may

In the larval stages of Drosophila, CA and prothoracic gland (PG) are located in a structure called ring gland. Previous report indicates that some neurosecretory cells near the mushroom bodies extent their axonal processes into CA of the ring gland. However, the developmental changes of CA and the upstream regulator of those CA-innervated neurons are still unclear. In this thesis, I used confocal analysis

Abstract:

We have evaluated the spatial relationship between local blood flow and the structural integrity of layer 5 cortical neurons in YFP-H transgenic mice 2-10 h after stroke. Fortuitously, ischemic zones could be finely mapped with respect to dysmorphic YFP labelled axons and dendrites using histology since texas-red dextran used to measure blood flow in vivo was trapped within fixed ischemic vessels. Ischemic damage to layer 5 neurons located at the border of ischemia was contained within apical tuft dendrites and did not propagate to deeper dendrites despite the potential for diffusion of releas

Abstract:

Next generation sequencing technologies are changing the way scientific experiments and diseases diagnostics are performed and thus will allow what is called personalized medicine. The sense of presented thesis is to make survey of new approaches to DNA sequencing and demonstrate usage and constraints of bioinformatic analytical tools available to day. Discussed techniques are then applied to the case study of finding molecular basis for rare hereditary disease. Introductory part deals with overview of commercially available sequencing techniques (454 Life Science, Applied Biosystems, Illumina

Abstract:

Imaging methods for visualizing synaptic contacts within neuronal circuits are under constant development and could contribute to the generation of a connectome of the striatum, which will be crucial to decode how striatal cells integrate motor information1–4. We attempted to optimize the mammalian GFP reconstitution across synaptic partners (mGRASP) technique to better understand how spiny projection neurons (SPNs) integrate input information from cortical intratelencephalic (IT) and pyramidal tract (PT) neurons. In order to do that, we set out to map corticostriatal inputs to SPNs with

Neuronale Plastizität ist die Voraussetzung für Lernen und Erinnerung. Sie wurde in einer Reihe von Experimenten am Menschen und am Tier eindrucksvoll demonstriert. Das zugrunde liegende Prinzip neuronaler Plastizität ist die Modulierbarkeit synaptischer Übertragungseffizienz. Diese kann im Sinne einer Langzeitpotenzierung (LTP) sowohl hinauf als auch im Sinne einer Langzeitdepression (LTD) herab reguliert werden. Von besonderem Interesse im Allgemeinen und für diese Arbeit ist das Prinzip der assoziativen LTD: Wirkt auf das postsynaptische Neuron zunächst ein starker depolarisierender Reiz un

Over the past decades, linkage analysis has been appropriate approach to search for the genes causing Mendelian diseases and contributed to the identification of many genes, but the genetic cause of many diseases remains unknown.

Abstract:

Few of these systems provide function that renders only two or more volume data at the same time. In this thesis, we build a texture-based multi-volume visualization system that renders up to six channel volume image. The system is applied to render volume images of neurons. To enhance the neuron in each volume, our system supports many “real-time” effects such as depth enhancement, NPR, lighting, transfer function, and pre-integrated volume rendering. These

Abstract:

The neuronal and molecular mechanisms underlying behavioral responses triggered by fear have received wide interest in the last few years, and various preclinical studies have addressed potential treatments for fear-related disorders. The central histaminergic system is an important modulator of memory related to adverse events and the integrity of the brain histamine system is necessary for the consolidation of this type of memory. Therefore, the use of antihistaminic drugs could be useful for the treatments of conditions such as obsessive-compulsive disorders, post-traumatic stress disorders
