Insight Into

Reflecting on the debts collected by Shoshana Felman's work, within the theoretical contexts of the time in which the 1977 Yale French Studies issue of ‘Psychoanalysis and Literature’ first appeared, this article takes as its point of departure Lacan's analysis of Hamlet's father as the barred Other, focusing on Hamlet's ‘complaint’. The nature of the complaint (plainte, or Klage, also closely allied to Anklage, or accusation) is then explored in relation to various writers and thinkers — Rilke, Benjamin, Nietzsche, Heidegger, among others — and more specifically via a reading of François Roustang's La Fin de la plainte (The End of the Complaint), and his own interpretations of Freudian narcissism. Scanning the wreckage for which the little narcissists are responsible, the article aims to give more insight into the structuring principles of those who whine incessantly.

AbstractThe vagus nerve is the largest autonomic nerve, innervating nearly every organ in the body. “Vagal tone” is a clinical measure believed to indicate overall levels of vagal activity, but is measured indirectly through the heart rate variability (HRV). Abnormal HRV has been associated with many severe conditions such as diabetes, heart failure, and hypertension. However, vagal tone has never been directly measured, leading to disagreements in its interpretation and influencing the effectiveness of vagal therapies. Using custom carbon nanotube yarn electrodes, we were able to chronically record neural activity from the left cervical vagus in both anesthetized and non-anesthetized rats. Here we show that tonic vagal activity does not correlate with common HRV metrics with or without anesthesia. Although we found that average vagal activity is increased during inspiration compared to expiration, this respiratory-linked signal was not correlated with HRV either. These results represent a clear advance in neural recording technology but also point to the need for a re-interpretation of the link between HRV and “vagal tone”.

During the last decade, optogenetics has become an essential tool for neuroscience research due to its unrivaled feature of cell-type-specific neuromodulation. There have been several technological advances in light delivery devices. Among them, the combination of optogenetics and electrophysiology provides an opportunity for facilitating optogenetic approaches. In this study, a novel design of an optrode array was proposed for realizing optical modulation and electrophysiological recording. A 4 × 4 optrode array and five-channel recording electrodes were assembled as a disposable part, while a reusable part comprised an LED (light-emitting diode) source and a power line. After the characterization of the intensity of the light delivered at the fiber tips, in vivo animal experiment was performed with transgenic mice expressing channelrhodopsin, showing the effectiveness of optical activation and neural recording.
