   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural modulation; infrared laser; in - vitro experiment; multi - electrode arrays MEA ; heating model; temperature; neural networks; infrared neural inhibition INI ; hyperexcitation;

   Sammanfattning : It would be of great value to have a precise and non-damaging neuromodulation technique in the field of basic neuroscience research and for clinical treatment of neurological diseases. Infrared neural modulation (INM) is a new modulation modality developed in the last decade, which uses pulsed or continues infrared (IR) light with a wavelength of 1200 to 2200 nm to directly alter neural signals.

   Författare :Martin Larhammar; Klas Kullander; Leif Andersson; Åsa Wallén-Mackenzie; Robert Fyffe; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Synaptic vesicle transporter; Neuromodulation; Dopamine; Central Pattern Generator; Locomotion; Gait; Horse; Mouse; Commissural Inhibitory Interneuron; Neuroscience; Neurovetenskap;

   Sammanfattning : Nerve cells are organized into complex networks that comprise the building blocks of our nervous system. Neurons communicate by transmitting messenger molecules released from synaptic vesicles. Alterations in neuronal circuitry and synaptic signaling contribute to a wide range of neurological conditions, often with consequences for movement. LÄS MER

7. 5. On Radio Wave Propagation Measurements and Modelling for Cellular Mobile Radio Networks

   Författare :Erik Östlin; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Field strength measurements; path loss prediction; point-to-area; Recommendation ITU-R P.1546; artificial neural network; large- and small-scale fading characteristics;

   Sammanfattning : To support the continuously increasing number of mobile telephone users around the world, mobile communication systems have become more advanced and sophisticated in their designs. As a result of the great success with the second generation mobile radio networks, deployment of the third and development of fourth generations, the demand for higher data rates to support available services, such as internet connection, video telephony and personal navigation systems, is ever growing.
