Alpha oscillations are a prominent electrophysiological signal measured across a wide range of species and cortical and subcortical sites. Alpha oscillations have been viewed for a long time as an "idling" rhythm, purely reflecting inactive sites. Despite earlier evidence from neurophysiology, awareness that alpha oscillations can substantially influence perception and behavior has grown only r...

There is increased awareness of the impact of gender and gonadal steroids on human cardiac rhythm and arrhythmias; e.g., drugs that prolong repolarization induce torsades de pointes (TdP) more frequently in women than men; female gender is an independent risk factor for syncope and sudden death in the congenital long QT syndrome; and the higher propensity toward arrhythmia in normal females is ...

PURPOSE OF REVIEW As the use of intracardiac devices has increased, the awareness of the burdens of the devices, especially the uncomfortable defibrillator shocks, has also increased. Some patients have requested device deactivation and some physicians have expressed reluctance to do so. This review will update physicians about the ethical acceptability of removal of intracardiac devices. REC...

The hippocampus is crucial for episodic or declarative memory and the theta rhythm has been implicated in mnemonic processing, but the functional contribution of theta to memory remains the subject of intense speculation. Recent evidence suggests that the hippocampus might function as a network hub for volitional learning. In contrast to human experiments, electrophysiological recordings in the...

The lowest frequencies are delta. These are less than 4 Hz and occur in deep sleep and in some abnormal processes, also during ex-periences of "empathy state". Delta waves are involved with our ability to integrate and let go. It reflects unconscious mind. It is the dominant rhythm in infants up to one year of age and it is present in stages 3 and 4 of sleep. It tends to be the highest in ampli...

Delayed sleep phase disorder (DSPD) is a disorder where the circadian rhythm is delayed according to the conventional norms, often resulting in schooland work related difficulties as well as emotional challenges. Research on the experiences of having DSPD is lacking, and to enhance our understanding we conducted a qualitative study using indepth semi structured interviews focusing on the challe...

Pacemaker syndrome was first described in 1969 by Mitsui when it was referred to as the pacemaking syndrome.' The name pacemaker syndrome was first coined by Erbel (using the German Schrittmacher syndrom) in 1979.2 It can present with symptoms as severe as syncope, presyncope, oedema, dyspnoea, and chest pain, or more moderately and subtly as lethargy, palpitation, or an awareness of venous pul...

Selective attention is related to a range of cognitive abilities, including executive function (Lawson et al., 2014). Orienting attention to visual and auditory targets are component skills inherent in many cognitive assessments, making it often difficult to parse cognitive capacities from selective attention abilities.The fundamental, early-developing nature of somatosensory processing (Saby e...
