Conducting polymer coated neural recording electrodes

Journal of Neural Engineering, 2012
Neural recording electrodes suffer from poor signal to noise ratio, charge density, biostability and biocompatibility. This paper investigates the ability of conducting polymer coated electrodes to record acute neural response in a systematic manner, allowing in depth comparison of electrochemical and electrophysiological response.Polypyrrole (Ppy) and

Electrochemical polymerization of conducting polymers in living neural tissue [PDF]

Journal of Neural Engineering, 2007
A number of biomedical devices require extended electrical communication with surrounding tissue. Significant improvements in device performance would be achieved if it were possible to maintain communication with target cells despite the reactive, insulating scar tissue that forms at the device-tissue interface.

Effect of the topology and delayed interactions in neuronal networks synchronization. [PDF]

PLoS ONE, 2011
As important as the intrinsic properties of an individual nervous cell stands the network of neurons in which it is embedded and by virtue of which it acquires great part of its responsiveness and functionality.

Altered Neural Responses to Punishment Learning in Conduct Disorder [PDF]

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging
Conduct disorder (CD) is associated with deficits in the use of punishment for reinforcement learning (RL) and subsequent decision making, contributing to reckless, antisocial, and aggressive behaviors. Here, we used functional magnetic resonance imaging (fMRI) to examine whether differences in behavioral learning rates derived from computational ...

Tunable nanostructured conducting polymers for neural interface applications [PDF]

2017 39th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2017
Advancement in the development of traditional metallic-based implantable electrodes for neural interfacing has reached a plateau in recent years in terms of their ability to provide safe, long-term, and high resolution stimulation and/or recording.
