2. 1. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges

   Author : Maria Asplund; Hans von Holst; Olle Inganäs; Thomas Stieglitz; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neuroprosthetics; conjugated polymers; conducting polymers; PEDOT; functional electrical stimulation; neural electrodes; Medical engineering; Medicinsk teknik; Neuroscience; Neurovetenskap; Functional materials; Funktionella material;

   Abstract : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.

4. 2. Infrared Neural Modulation: Photothermal Effects on Cortex Neurons Using Infrared Laser Heating

   Author : Qingling Xia; Tobias Nyberg; Björn Granseth; KTH; []
   Keywords : 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;

   Abstract : 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.

5. 3. Neural control of inflammation

   Author : April S Caravaca; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Pioneering research on neural control of inflammation has paved the way for new and exciting developments in the growing field of bioelectronic medicine. In the past couple of decades, pre-clinical research on the role of the vagus nerve in inflammation and immunity has brought electrical stimulation of select nerves into clinical trials for the treatment of chronic inflammatory diseases.

6. 4. Microelectrode cluster technology for precise interactions with neuronal circuits. Towards highly specific adaptive deep brain stimulation

   Author : Mohsin Mohammed; Neuronano Research Center (NRC); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neuro-electronic interfaceneural interface; neural interface; tissue reactions; deep brain stimulation; Adaptive DBS; biocompatibility; implantation method; neurosurgical tool;

   Abstract : Neuro-electronic interfaces, which can be used for stable communication between neurons-computers over long periods of time, would be valuable for understanding and interacting with the nervous system. A major challenge has been to overcome the tissue reactions towards implanted electrodes. READ MORE

7. 5. Neural control of standing posture

   Author : Craig Tokuno; Andrew Cresswell; Alf Thorstensson; Marc Carpenter; Thomas Sinkjær; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Medicin Teknik; Medicine Technology; Posture; motor cortex; electromyography; kinematics; H-reflex; pre-synaptic inhibition; transcranial magnetic stimulation;

   Abstract : When humans are asked to stand normally, they are not completely motionless. Rather, small amounts of body movement, termed postural sway, can be observed. Although the postural sway of standing has been well described, the manner in which this sway is neurally controlled and its influence in tasks involving postural re-stabilization are not known.
