Astrocytes are star-shaped glia cells and the most common cell type in the human brain with neurons. Astrocytes fulfill many functions in human brain. Providing support to the cells of the blood-brain barrier, balancing the extracellular ion concentration, supplying nutrients to the nerve tissue, and controlling the development of nerve cells are some of these tasks. In this study, the effects of calcium (Ca') ion concentration oscillations occuring in astrocytes on the neuron firing dynamics are investigated. When the obtained results are examined, it is observed that the production rate of insole 1,4,5-triphosphate (IP3), which is . . . an agent that triggers calcium release from the resoruces in astrocytes, and the degradation time of that within the cell are important effects on the spike production dynamics of the neuron in contact with astrocyte. It is determined that neurons without any stimulation continue to produce spikes through calcium oscillations in the astrocytes, at high IP3 production rates and longer IP3 degradation times Daha fazlası Daha az

In this study, it was implemented a wristband design which provides distance measurements to assist blind people. The obstacles were detected by the help of ultrasonic sensors connected to an Arduino microcontroller board. A design that can be adapted to different usage areas (indoor or outdoor) and various stimulus types (vibration only, sound only, both together), is produced, which concerns user needs. The designed system was successfully tested by a healthy individual. As a result, a design was achieved, which is open to be improved by adding the house plan and furniture locations in near future.
