BACKGROUND: Although relapse in psychosis is common, a small proportion of patients will not relapse in the long term. We examined the proportion and predictors of patients who never relapsed in the 10 years following complete...
A shared representation of order between encoding and recognition in visual short-term memory.
Many complex tasks require people to bind individual events into a sequence that can be held in short term memory (STM). For this purpose information about the order of the individual events in the sequence needs to be...
The devil's in the detail
Models of memory propose that separate systems underpin the storage and recollection of specific events from our past (e.g., the first day at school), and of the generic structure of our experiences (e.g., how lonely I am), and...

Oct 03, 2018
BACKGROUND: Alzheimer's disease and related forms of dementia are becoming increasingly prevalent with the aging of many populations. The diagnosis of Alzheimer's disease relies on tests to evaluate cognition and discriminate...

Working memory deficits are present in many neuropsychiatric diseases with diagnosis-related severity. However, it is unknown whether this common behavioral abnormality is a continuum explained by a neural mechanism shared...

Functional neuroimaging of the interference between working memory and the control of periodic ankle movement timing.
BACKGROUND: Limited information processing capacity in the brain necessitates task prioritisation and subsequent adaptive behavioural strategies for the dual-task coordination of locomotion with severe concurrent cognitive...
Communication from Learned to Innate Olfactory Processing Centers Is Required for Memory Retrieval in Drosophila.

Visual recency bias is explained by a mixture model of internal representations.
Human bias towards more recent events is a common and well-studied phenomenon. Recent studies in visual perception have shown that this recency bias persists even when past events contain no information about the future. Reasons...
Drift in Neural Population Activity Causes Working Memory to Deteriorate Over Time.
Short-term memories are thought to be maintained in the form of sustained spiking activity in neural populations. Decreases in recall precision observed with increasing number of memorized items can be accounted for by a limit...

The neural basis of precise visual short-term memory for complex recognisable objects.
Recent evidence suggests that visual short-term memory (VSTM) capacity estimated using simple objects, such as colours and oriented bars, may not generalise well to more naturalistic stimuli. More visual detail can be stored in...
Autobiographical episodic memory-based training for the treatment of mood, anxiety and stress-related disorders
We review evidence for training programmes that manipulate autobiographical processing in order to treat mood, anxiety, and stress-related disorders, using the GRADE criteria to judge evidence quality. We also position the...

Investigating Fast Mapping Task Components
Fast mapping (FM) is an incidental learning process that is hypothesized to allow rapid, cortical-based memory formation, independent of the normal, hippocampally dependent episodic memory system. It is believed to underlie the...
Structural optimality and neurogenetic expression mediate functional dynamics in the human brain.
The human brain exhibits a rich functional repertoire in terms of complex functional connectivity patterns during rest and tasks. However, how this is developed upon a fixed structural anatomy remains poorly understood. Here we...
Communism and Memory Politics in the European Union
D J Clarke
Aug 13, 2014
This article assesses the potential for memory of communism to become
part of the EU’s memory culture by comparing three contrasting case studies:
the Baltic states, Hungary, and Germany. It argues that, rather than...

Cognitive Decline in Mild Cognitive Impairment With Lewy Bodies or Alzheimer Disease

Aug 07, 2020
OBJECTIVE: We explored whether the mild cognitive impairment (MCI) stages of dementia with Lewy bodies (DLB) and Alzheimer disease (AD) differ in their cognitive profiles, and longitudinal progression. DESIGN: A prospective...
Hierarchical Representation of Multistep Tasks in Multiple-Demand and Default Mode Networks.
Task episodes consist of sequences of steps that are performed to achieve a goal. We used fMRI to examine neural representation of task identity, component items, and sequential position, focusing on two major cortical...
The use of commercial computerised cognitive games in older adults
Brain training programs are currently one effective solution to prevent cognitive decline in healthy aging. We conducted a meta-analysis of randomized controlled trials assessing the use of commercially available computerised...

Down's syndrome is a chromosomal disorder that invariably results in both intellectual disability and Alzheimer's disease neuropathology. However, only a limited number of studies to date have investigated intrinsic brain...

Cerebral cortex layer segmentation using diffusion magnetic resonance imaging in vivo with applications to laminar connections and working memory analysis.
Understanding the laminar brain structure is of great help in further developing our knowledge of the functions of the brain. However, since most layer segmentation methods are invasive, it is difficult to apply them to the...
