This textbook presents a broad overview of topics concerning cellular electrophysiology – covering topics ranging from bioelectric phenomena recognized as far back as ancient Egypt to popular topics on the dangers of electrosmog. Without sacrificing scientific precision, this clear and concise work presents on the one hand the different methods and applications, on the other hand the biophysical fundamentals of ion-channel and carrier proteins. Numerous and carefully selected illustrations and diagrams supplement the text, while questions at the end of each chapter allow readers to test their understanding. Each section also includes references to relevant original literature for further reading. The book offers a valuable resource for students of biology, chemistry and physics with a special interest in biophysics.

In this thesis, the author investigates the biophysical basis of the local field potential (LFP) as a way of gaining a better understanding of its underlying physiological mechanisms. The results represent major advances in our understanding and interpretation of LFPs and brain oscillations. They highlight the importance of using suitable experimental and analytical methods to explore the activity of brain circuits and point to the LFP as a useful, but complex variable for this purpose.

This book has been conceives as a brief introduction to biomembranes physical chemistry for undergraduate students of sciences, and it is particularly dedicated to the lipid-protein membrane interactions. A general introduction is presented in Chapters 1 and 2. The following Chapters, 3 and 4, describe the most accepted theories on lipid-membrane protein interactions as well as the new experimental approaches, in particular, these arose from nano sciences as atomic for microscopy and single molecule force spectroscopy. The book emphasizes the relevance of physical parameters as the lateral surface pressure and the lipid curvature as actors for understanding the physicochemical properties of the biomembranes.

Ring polymers are one of the last big mysteries in polymer physics, and this thesis tackles the problem of describing their behaviour when interacting in dense solutions and with complex environments and reports key findings that help shed light on these complex issues. The systems investigated are not restricted to artificial polymer systems, but also cover biologically inspired ensembles, contributing to the broad applicability and interest of the conclusions reached. One of the most remarkable findings is the unambiguous evidence that rings inter-penetrate when in dense solutions; here this behaviour is shown to lead to the emergence of a glassy state solely driven by the topology of the constituents. This novel glassy state is unconventional in its nature and, thanks to its universal properties inherited from polymer physics, will attract the attention of a wide range of physicists in the years to come. .
