Transient Global Amnesia Deteriorates the Network Efficiency of the Theta Band [PDF]
, 2016 Acute perturbation of the hippocampus, one of the connector hubs in the brain, is a key step in the pathophysiological cascade of transient global amnesia (TGA).

Transient global amnesia or transient epileptic amnesia? [PDF]
QJM: An International Journal of Medicine, 2005 Sir, We read with great interest the letter of McCorry and Crowley1 concerning an attack of transient global amnesia (TGA) considered secondary to herpes simplex viral encephalitis. Some features of the reported attack are unusual. The patient was a relatively young person: 39 years compared with an average age of 61 with TGA.2 At the beginning the ...

Quantum Amnesia Leaves Cryptographic Mementos: A Note On Quantum Skepticism [PDF]
arXiv, 2022 Leonard Shelby, the protagonist of Memento, uses mementos in the form of tattoos and pictures to handle his amnesia. Similar to Leonard, contemporary quantum computers suffer from "quantum amnesia": the inability to store quantum registers for a long duration. Quantum computers can only retain classical "mementos" of quantum registers by measuring them

Long Chaotic Transients in Complex Networks [PDF]
Phys. Rev. Lett. 93, 244103 (2004), 2004 We show that long chaotic transients dominate the dynamics of randomly diluted networks of pulse-coupled oscillators. This contrasts with the rapid convergence towards limit cycle attractors found in networks of globally coupled units. The lengths of the transients strongly depend on the network connectivity and varies by several orders of magnitude ...

Selective Amnesia: A Continual Learning Approach to Forgetting in Deep Generative Models [PDF]
arXiv, 2023 The recent proliferation of large-scale text-to-image models has led to growing concerns that such models may be misused to generate harmful, misleading, and inappropriate content. Motivated by this issue, we derive a technique inspired by continual learning to selectively forget concepts in pretrained deep generative models.

'Unforgettable' : a pictorial essay on anatomy and pathology of the hippocampus [PDF]
, 2017 The hippocampus is a small but complex anatomical structure that plays an important role in spatial and episodic memory. The hippocampus can be affected by a wide range of congenital variants and degenerative, inflammatory, vascular, tumoral and toxic ...

Analysis of the smoothly amnesia-reinforced multidimensional elephant random walk [PDF]
arXiv, 2023 In this work, we discuss the smoothly amnesia-reinforced multidimensional elephant random walk (MARW). The scaling limit of the MARW is shown to exist in the diffusive, critical and superdiffusive regimes. We also establish the almost sure convergence in all of the three regimes.

What went wrong? The flawed concept of cerebrospinal venous insufficiency [PDF]
, 2013 In 2006, Zamboni reintroduced the concept that chronic impaired venous outflow of the central nervous system is associated with multiple sclerosis (MS), coining the term of chronic cerebrospinal venous insufficiency ('CCSVI'). The diagnosis of 'CCSVI' is

Alzheimer's &Dementia, EarlyView.Abstract US clinical practice guidelines for the diagnostic evaluation of cognitive impairment due to Alzheimer's disease (AD) or AD and related dementias (ADRD) are decades old and aimed at specialists. This evidence‐based guideline was developed to empower all—including primary care—clinicians to implement a structured approach for evaluating a ...
