Neuronal regeneration: lessons from the olfactory system.

Neuronal regeneration takes place in the primary relay of the ( ) olfactory system, the olfactory epithelium OE ; however, its synaptic target in the central nervous system, the olfactory ( ) bulb OB , undergoes continual neurogenesis but not true regeneration. In this review, cell interactions and growth factors regulating neurogenesis in both OE and OB are discussed. In addition, regulation o...

Tomato Value Chain Information System in Tanzania: Lessons from Kilolo District and Dodoma Municipality, Tanzania

The major challenge for the tomato farmers is getting a fair price at the market price given that there are many actors involved in the tomato value chain. Given this situation, this project's goal was to improve communication pathways in dissemination of agricultural market information in tomato value chains in Iringa and Dodoma Regions in Tanzania. The specific objectives were to: identify an...

Quality Coding by Neural Populations in the Early Olfactory Pathway: Analysis Using Information Theory and Lessons for Artificial Olfactory Systems

In this article, we analyze the ability of the early olfactory system to detect and discriminate different odors by means of information theory measurements applied to olfactory bulb activity images. We have studied the role that the diversity and number of receptor neuron types play in encoding chemical information. Our results show that the olfactory receptors of the biological system are low...

Development of Neural Network Information Retrieval System from Text Documents

The aim of the paper is to describe the information retrieval model which retrieves information from text documents in natural language by neural networks. This model comes from the linguistic and conceptual approach for the analysis of text documents. The neural network model accepts the structure of conceptual, lingvistic oriented model, where the problem of document database creation and doc...

Axon-axon interactions in neuronal circuit assembly: lessons from olfactory map formation.

During the development of the nervous system, neurons often connect axons and dendrites over long distances, which are navigated by chemical cues. During the past few decades, studies on axon guidance have focused on chemical cues provided by the axonal target or intermediate target. However, recent studies have shed light on the roles and mechanisms underlying axon-axon interactions during neu...
