Left atrium appendage closure is a safe and effective therapy for patients with atrial fibrillation and high thromboembolic and hemorrhagic risks. Prosthesis embolization is a potential major complication with an incidence of 0.07%. We report a case of migration of an Amplatzer Amulet (Abbott) device that was successfully retrieved in an innovative way (4).

An individual shows handedness when they consistently prefer one hand over the other for tasks that can be performed with either hand. Humans have a population-level right-hand preference, and past research shows that a variety of nonhuman primate species also show hand preferences. More complex manual tasks elicit stronger hand preferences than less complex manual tasks, but not much is known about hand preferences during a cognitive task in nonhuman primates.

Pronouns create cohesive links in discourse by referring to previously mentioned elements. Here, we focus on pronominalization during speech production in three experiments employing ERP and fMRI methodologies. Participants were asked to produce two short sentences describing a man or woman using an object.

Background: Normative percentile (NP) quantifies brain atrophy by comparing regional brain volumes of a subject against age and sex‐matched cognitively normal populations. Accurate intracranial volume (ICV) adjustment is vital in NP quantification to minimize the effect of an individual’s head size. However, which intracranial volume adjustment method yields reliable normative percentiles remains unclear.

Background: Episodic memory declines during healthy aging and is often reported as an early symptom of Alzheimer’s disease (AD). However, standardized assessments of memory performance are limited in their accuracy to predict progression of early‐stage AD pathology. The ‘all‐or‐none’ approach commonly used in neuropsychological assessment for quantifying memory performance might miss out on subtle variation in the fidelity or quality mnemonic representations retrieved from memory.

Background: Past studies show that amygdala atrophy may be involved in the early stages of Alzheimer's disease (AD). AD is characterized by progressive cognitive decline, and changes in the amygdala—interconnected with various brain regions involved in cognition—could contribute to memory and emotional processing impairments. Specifically, changes in amygdala volumes may affect these neural networks, contributing to cognitive decline through disrupted communication between brain regions.
