Developmental myelination and myelin plasticity during spatial working memory task acquisition
… differentiation, I employed a touchscreen-based spatial working memory task. A task that is similar to cognitive paradigms used for humans, allowing for potential translation to human cognitive functioning. In summary, I find that myelin develops in a specific pattern over time in the mouse …

A Behavioral Study on the Adult Marmoset Interference Control in Spatial Working Memory
Interference control deficit in Working Memory (WM) is associated with neurodevelopmental disorders. The common marmoset (Callithrix jacchus) is an ideal non-human animal model for studying WM disorders. Previous studies of marmoset WM have used a touch-screen self-ordered sequencing task (SOST), …

The role of reuniens and rhomboid thalamic nuclei in spatial memory
<p>Spatial working memory is the ability to encode and temporarily store information for future retrieval to guide behavioral responses. Two areas of the brain that are important for this process are prefrontal cortex (PFC) and hippocampus. The hippocampus has strong connections to medial PFC, …

Beneficial Effect of the Flavonoid Luteolin on Neuroinflammation
… luteolin can ameliorate age-related deficits in spatial working memory and reduce inflammatory molecules in aged brain. Adult and aged mice were provided control or luteolin supplemented diet for four weeks. Dietary supplementation of luteolin attenuated the age-related spatial working memory …

Gender Differences in Working Memory in Humans Tested on a Virtual Morris Water Maze.
… was used to assess human gender differences in spatial working memory. In Experiment 1, the release point and platform location was changed on every other trial for 20 trials. Men had significantly reduced acquisition latencies and more accurate heading errors on the first daily trial compared …

Electrophysiological Correlates of Cognitive Processing in Adolescents Reporting Psychotic-Like Experiences
… an Active Auditory Oddball Task, an Implicit Spatial Memory Task and a Spatial Working Memory Task. The present thesis is the first study to examine resting state data and the electrophysiological correlates of auditory and spatial processing in adolescents reporting PLEs. In Chapter 3 the …

Functional dissociation between visual and spatial temporary maintenance
… the functional dissociation between visual and spatial working memory systems by the use of dual-task interference methodology. Two temporary maintenance tasks that are putatively assumed to rely on visual and spatial memory resources respectively, i.e., retention of visual items (geometric …

Investigating the relationship of verbal span and spatial span in a combination task
Measurement of working memory span typically involves tasks designed to introduce stimuli to the unique slave systems. It is widely accepted that these isolated measurements indicate, at a relatively simple level, the span of the given working memory system. This study hypothesizes that separate …

Linking dopaminergic physiology to working memory related neural circuitry
Working memory is the ability to hold information "online" over a delay in order to perform a task. This kind of memory is thought to be encoded in the brain by persistent neural activity that outlasts the presentation of a stimulus. Interestingly, patients with schizophrenia, a heritable …

Exploring the Relationships Between Children's Working Memory and Long-Term Memory
Working memory and long-term memory are two types of memory associated with children’s learning and academic performance. A number of memory models have suggested there is a relationship between working memory and long-term memory; however, there is a lack of empirical research measuring this …

Working memory and human reasoning : an individual differences approach
… 1-3 investigated the relationship between working memory and syllogistic and five-ten-n series spatial inference. A secondary aim was to replicate the findings of Shah and Miyake (1996) who suggested the use of separate central resources of working memory for spatial and verbal ability. The …

Long-range synchrony between medial prefrontal cortex, thalamus and hippocampus underlies working memory behavior in mice.
… an understanding of functional cognition. Spatial working memory, a measure of cognitive function, can be assessed in the mouse using a task of delayed alternation: the T-maze. In this thesis, I focus on spatial working memory behavior in the mouse and three brain regions that are …

EFFECTS OF ENHANCING ANANDAMIDE LEVELS ON HIPPOCAMPAL NEUROPHYSIOLOGY AND SHORT-TERM MEMORY PROCESSING IN RATS
The endocannabinoids affect spatial-working memory by altering neuronal activity of pyramidal neurons present in the hippocampus. In this study extracellular action potentials were recorded using multi-neuron electrodes implanted in the CA1 and CA3 subfields of the hippocampus. The acute effects of …

Tower of California Performance Early in Parkinson's Disease
… specifically in the areas of planning and spatial working memory. It is predicted that the early PD group will perform worse than the control group but better than the late PD group in the number of successful towers (ST) built. The early PD group is also expected to have a longer time to …

Binge Alcohol Effects on the Prefrontal Cortex
… than their respective control groups, as well as spatial working memory deficits detected during behavioral testing. No differences were found between binged male and binged female rats on neuronal volume, population or behavioral outcomes. These results support prior research indicating that …

Relationships between physical activity and motor and cognitive function in young children
… Neuropsychological Test Battery (CANTAB) (working memory), the Attention Network Test (reaction time) the Cognitive Assessment System (CAS) (executive function), and the short form of Connor’s Parent Rating Scale (CPRS:S) (behaviour). Physical activity was measured using the Actigraph GT1M …

Mixed Dementia Induced by Right Common Carotid Artery Occlusion in an Alzheimer Mouse Model
… mice had both cognitive deficits on spatial memory and non-spatial working memory induced in AD and VCI models, respectively. Moreover, an impairment of learning curve was synergistically induced from both pathomechanisms.

Characterizing Cortex-Hippocampus Interactions During Language Processing
… outside its traditional roles in episodic memory and spatial navigation, and may generally aid in the encoding of relationships across time and space [Cohen and Eichenbaum, 1993]. Hence, the hippocampus may be involved in processes that are also implicated for language processing. Indeed, …

Investigation of the multiple-demand network at multiple spatial scales
… in a variety of different tasks including working memory, task switching, inhibition, math, language etc. While the different MD regions have partly different functions, they are highly interconnected allowing them to function together as a network. The experiment in Chapter 2 looked at the …

Examining Cognitive Processing in Children with an Arithmetic Disability
… examined the executive functioning and working memory of children with AD. An age-matched achievement-matched design was employed to explore whether children with AD exhibit developmental lags or deficits in these cognitive domains. While children with AD did not exhibit impairments in …
