Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Sleep spindles are an electrophysiological fingerprint of the sleeping human brain. They can be described in terms of duration, frequency, amplitude, and density, and vary widely according to age and sex. Spindles play a role in sleep and wake functions and are altered in several neurological and psychiatric disorders.

Antidepressant suppression of REM and spindle sleep impairs hippocampus-dependent learning and memory but fosters striatal-dependent strategies [PDF]
, 2011 REM sleep enhances hippocampus-dependent associative memory but has little impact on striatal-dependent procedural learning. Antidepressant medications like desipramine (DMI) inhibit rapid-eye-movement (REM) sleep but it is little understood how ...

A Novel Approach to Implementing Artificial Thalamic Neurons with Ferroelectric Transistors
Advanced Functional Materials, EarlyView.Artificial neurons created using CMOS technology often require a large number of transistors and capacitors. This study introduces an artificial thalamic neuron that employs only five CMOS compatible ferroelectric transistors. The manufactured thalamic neuron demonstrates leaky integrate‐and‐fire‐or‐burst (LIFB) functionalities, featuring self ...

REM sleep without atonia with REM sleep–related motor events: broadening the spectrum of REM sleep behavior disorder [PDF]
Sleep, 2018 To assess the presence of increased REM-related motor activity during sleep, by questionnaires for REM sleep behavior disorder (RBD), in participants with "isolated" REM sleep without atonia (RWA).Two hundred forty-nine patients were consecutively enrolled, with age ≥18 years, sharing bedroom with a roommate, and without a severe health, neurological ...
