Information in small neuronal ensemble activity in the hippocampal CA1 during delayed non-matching to sample performance in rats

BMC Neuroscience, 2009
Background The matrix-like organization of the hippocampus, with its several inputs and outputs, has given rise to several theories related to hippocampal information processing.

Emotional Working Memory in Alzheimer’s Disease Patients

Dementia and Geriatric Cognitive Disorders Extra, 2011
Background: Few studies have assessed whether emotional content affects processes supporting working memory in Alzheimer disease (AD) patients. Methods: We assessed 22 AD patients and 40 elderly controls (EC) with a delayed matching and non-matching to ...

Assessment of Working Memory in Students with Autism and/or Intellectual Disabilities Using Eye Tracking [PDF]

Psicologia: Teoria e Pesquisa
Working memory was assessed with delayed matching-to-sample, with eye tracking. The case study aimed to analyze eye tracking in a matching-to-sample task with delays of 0, 4 and 8 seconds, and 20 minutes, with social and non-social stimuli.

Direct admission to the intensive care unit from the emergency department and mortality in critically ill hematology patients [PDF]

, 2019
Background: The aim of this study was to assess the benefit of direct ICU admission from the emergency department (ED) compared to admission from wards, in patients with hematological malignancies requiring critical care.

Sub-millisecond firing synchrony of closely neighboring pyramidal neurons in hippocampal CA1 of rats during delayed non-matching to sample task

Frontiers in Neural Circuits, 2009
Firing synchrony among neurons is thought to play functional roles in several brain regions. In theoretical analyses, firing synchrony among neurons within sub-millisecond precision is feasible to convey information.

Different Influences of Negative and Neutral Emotional Interference on Working Memory in Trait Anxiety

Frontiers in Psychology, 2021
To examine the interaction of working memory (WM) type with emotional interference in trait anxiety, event-related potentials were measured in a combined WM and emotional task. Participants completed a delayed matching-to-sample task of WM, and emotional

Differential associations of visual memory with hippocampal subfields in subjective cognitive decline and amnestic mild cognitive impairment

BMC Geriatrics, 2022
Background Although previous studies have demonstrated that the hippocampus plays a role in verbal memory, the role of hippocampal subfields in visual memory is uncertain, especially in those with preclinical Alzheimer's disease (AD). This study aimed to

A model for integrating elementary neural functions into delayed-response behavior. [PDF]

PLoS Computational Biology, 2006
It is well established that various cortical regions can implement a wide array of neural processes, yet the mechanisms which integrate these processes into behavior-producing, brain-scale activity remain elusive.

Item and error analysis on Raven's Coloured Progressive Matrices in Williams Syndrome [PDF]

, 2010
Raven's Coloured Progressive Matrices (RCPM) is a standardised test that is commonly used to obtain a non-verbal reasoning score for children. As the RCPM involves the matching of a target to a pattern it is also considered to be a visuo-spatial ...
