Abstract

The inferior colliculus (IC) is a unique structure in the auditory system, located between the primary auditory nuclei of the brainstem and the thalamus. The existence of the complex neural circuits in the auditory brainstem and midbrain, lacking in other sensory systems, has motivated an outpouring of research on the circuitry and physiological properties of the IC. IC neurons receive ascending inputs from over 20 separate sources in the brainstem as well as a dense collection of descending connections from the cortex. It is richly connected to both the left and right ears through these circuits and a major theme in research on the IC has been its role in binaural interactions. A second theme is the role of descending circuits in modulating responses to sound in the IC. A third theme is understanding the sound processing that occurs at the level of the IC, essentially how the representation of sound in the IC differs from that in the two auditory nerves. The representation of sound in the IC is an intermediate step in the development of the cortical representation as well as in the development of many perceptual features of sounds. These characteristics have been documented for a number of computations, including sound localization, masking properties, robustness of the representation, and responses to temporal and spectral properties of sounds. This Research Topic aims to discuss a wide range of aspects of the structure and function of the IC in a way that will facilitate future research.

Abstract

The most commonly used measurement technique for electrophysiology is the patch clamp technique. While this measurement technique allows the precise investigation of the communication taking place through ion channels, it has some undesirable drawbacks such as the local destruction of the plasma membrane, a low success rate and an elaborate experimental procedure. To avoid these drawbacks, in this work a new non-invasive microfluidic platform for electrophysiological research (NIMEP) was developed with regard to the activity of ion channels. This novel approach is based on the non-invasive measurement of the total current through the cell membrane and provides a possibility for an automated investigation of the individual cells. In addition, the investigated cell can be used for other applications, since the cell remains in an intact state before and after the test.

Abstract

A well-adjusted expression of cardiac ion channels at the sarcolemma is of crucial importance for normal action potential formation and thus cardiac function. The cellular processes that transport channel proteins from the endoplasmic reticulum towards specified regions on the sarcolemmal membrane, and subsequently take them from the plasma membrane to the protein degradation machinery are commonly known as trafficking. The research field recognizes that aberrant channel trafficking stands at the basis of many congenital and acquired arrhythmias. The collection of papers in this eBook provides state-of-the-art insight into the world of ion channel trafficking research.

Abstract

The emergence of marine and freshwater toxins in geographical areas where they have never been reported before is a concern due to the considerable impact on (sea)food contamination, and consequently, on public health. Several groups of marine biotoxins, in particular tetrodotoxins, ciguatoxins, and palytoxins, are included among the relevant marine biotoxins that have recently emerged in several coastal areas. A similar situation has been observed in freshwater, where cyanobacterial toxins, such as microcystins, could end up in unexpected areas such as the estuaries where shellfish are cultivated. Climate change and the increased availability of nutrients have been considered as the key factors in the expansion of all of these toxins into new areas; however, this could also be due to more intense biological invasions, more sensitive analytical methods, or perhaps even an increased scientific interest in these natural contaminations. The incidences of human intoxications due to the consumption of seafood contaminated with these toxins have made their study an important task to accomplish in order to protect human health. This Special Issue has a focus on a wide variety of emerging biotoxin classes and techniques to identify and quantify them.

Abstract

Almost 25 years ago, the first mammalian transient receptor potential (TRP) channel was cloned and published. TRP channels now represent an extended family of 28 members fulfilling multiple roles in the living organism. Identified functions include control of body temperature, transmitter release, mineral homeostasis, chemical sensing, and survival mechanisms in a challenging environment. The TRP channel superfamily covers six families: TRPC with C for “canonical”, TRPA with A for “ankyrin”, TRPM with M for “melastatin”, TRPML with ML for “mucolipidin”, TRPP with P for “polycystin”, and TRPV with V for “vanilloid”. Over the last few years, new findings on TRP channels have confirmed their exceptional function as cellular sensors and effectors. This Special Book features a collection of 8 reviews and 7 original articles published in “Cells” summarizing the current state-of-the-art on TRP channel research, with a main focus on TRP channel activation, their physiological and pathophysiological function, and their roles as pharmacological targets for future therapeutic options.

Abstract

Alzheimer’s disease (AD) is an age-related neurological disease that affects tens of millions of people, in addition to their carers. Hallmark features of AD include plaques composed of amyloid beta, as well as neurofibrillary tangles of tau protein. However, despite more than a century of study, the cause of Alzheimer’s disease remains unresolved. The roles of amyloid beta and tau are being questioned and other causes of AD are now under consideration. The contributions of researchers, model organisms, and various hypotheses will be examined in this Special Issue.
