The psychological refractory period (PRP) effect occurs when two stimuli that require separate responses are presented sequentially, particularly with a short and variable time interval between them. Fatigue is a suboptimal psycho-physiological state that leads to changes in strategies. In recent years, numerous…

We consider a stochastic process undergoing resetting after which a random refractory period is imposed. In this period the process is quiescent and remains at the resetting position. Using a first-renewal approach, we compute exactly the stationary position distribution and analyse the emergence of a delta peak at the…

As the third generation of neural networks, spiking neural networks (SNNs) have recently gained widespread attention for their biological plausibility, energy efficiency, and effectiveness in processing neuromorphic datasets. To better emulate biological neurons, various models such as Integrate-and-Fire (IF) and Leaky…

The primary outcome was the severity of depressive symptoms 12 months after randomisation, that is 5 months after the end of treatment. Trained assessors measured this by the 17-item HRSD.15 Participants completed the HRSD at four points - baseline, and 7 (immediately after treatment), 12 and 18 months after…

'Rakesh Kumar Gupta'] Background Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform attacks with cranial autonomic features (SUNA) are rare primary headache syndromes characterized by spontaneous or triggered attacks of unilateral…

Post-traumatic stress disorder (PTSD) is a frequent, tenacious, and disabling consequence of traumatic events. The disorder’s identifiable onset and early symptoms provide opportunities for early detection and prevention. Empirical findings and theoretical models have outlined specific risk factors and pathogenic…

Traumatic events lead to distressing memories, but such memories are made all the worse when they intrude to mind unbidden and recurrently. Intrusive memories are a hallmark of several mental health disorders including posttraumatic stress disorder (PTSD) and can persist for years. Critically, the reduction of…

Post-Traumatic Stress Disorder (PTSD) is fundamentally a neuroplastic problem traumatic contact events encode over-reactive neural pathways through Hebbian long-term potentiation, producing hair-triggered amygdala-HPA stress cascades that fire before conscious awareness can intercept them. Existing therapeutic…

Recently, scientists have shifted their focus from studying psychological resilience as a single, isolated construct (e.g. attribute or outcome) to studying it as a dynamic process encompassing a number of temporally related elements. Models depicting this process explain why some people adapt to stressor exposure…

Learning and memory play a central role in psychopathology, particularly in depression and posttraumatic stress disorder. We present a new, transdiagnostic theory of how memory and mood interact in emotional disorders. Drawing upon retrieved-context models of episodic memory, we propose that memories form associations…

Psychedelics have robust effects on acute brain function and long-term behavior but whether they also cause enduring functional and anatomical brain changes is unknown. In a placebo-controlled, within-subjects, electroencephalography, and magnetic resonance imaging study in 28 healthy, entirely psychedelic-naive…

Neurophysiological mechanisms underlying psychological resilience, the ability to overcome adversity^1,2^, have been extensively studied in animals. However, in comparison with animals, human resilience is unique in that it is underpinned by higher cognitive functions, such as self-confidence and a positive attitude to…

The research field focusing on the etiology, diagnosis and treatment of people with dissociative identity disorder (DID) is still relatively young and limited in scope. Until a few years ago, psychotherapeutic treatment for adults with DID consisted primarily of practice-based, phase-based psychodynamic psychotherapy…
