Differential effects of Alzheimer\u27s disease and Huntington\u27s disease on the performance of mental rotation [PDF]
, 2005 he ability to spatially rotate a mental image was compared in patients with Alzheimer\u27s disease (AD; n = 18) and patients with Huntington\u27s disease (HD; n = 18). Compared to their respective age-matched normal control (NC) group, the speed, but not

Mental rotation of tactual stimuli
Acta Psychologica, 1990 Three experiments involving different angular orientations of tactual shapes were performed. In experiment 1 subjects were timed as they made 'same-different' judgments about two successive rotated shapes. Results showed that no rotation effect is obtained, i.e., reaction times and error percentage do not increase linearly with rotation angle. The same

Dynamic Neural Deactivation Bridges Direct and Competitive Inhibition Processes
Advanced Science, EarlyView.Dynamic neural deactivation bridges traditionally distinct inhibitory mechanisms—direct inhibition and competition‐induced inhibition—revealing a common neural signature across modalities. Multimodal neuroimaging and behavioral experiments demonstrate a temporal dynamic characterized by progressive frontoparietal activation decay and enhanced sensory ...

Compensating for Large In-Plane Rotations in Natural Images
, 2016 Rotation invariance has been studied in the computer vision community primarily in the context of small in-plane rotations. This is usually achieved by building invariant image features.

Mental rotation in perspective problems
Acta Psychologica, 1991 The present paper demonstrates that mental rotation as used in the processing of disoriented objects (Cooper and Shepard 1973) can also be used as an explanatory concept for the processing of perspective problems in which the task is to imagine how an environment will appear from another vantage point.

Advanced Science, EarlyView.This work presents an automated and accessible point‐of‐care device, MEMOs, for the detection of exosomal Aβ42 protein, a potential blood biomarker for Alzheimer’s disease. MEMOs, with its automated operation workflow, minimizes hands‐on time and maintains high sensitivity in diagnosing AD, allowing non‐specialists to conduct tests at home and offering

Microglial Feimin Alleviates Cognitive Impairment in High‐Fat Diet‐Fed Mice
Advanced Science, EarlyView.Microglial feimin deletion exacerbates lipotoxicity‐induced neuroinflammation and cognitive decline. In both in vitro and in vivo models, loss of feimin aggravated lipid droplet accumulation, IL‐1β/IL‐6 release, and neuronal injury through the PI3K–AKT–mTOR pathway, ultimately leading to severe neuronal apoptosis and cognitive impairment under high‐fat

Advanced Science, EarlyView.A hybrid microneedle‐based biofuel cell composed of MXene/CNT/glucose oxidase bioanode and platinum/carbon cathode was prepared for wearable transdermal charged drug delivery system. It harvests the subcutaneous interstitial fluid energy and exhibits a stable transdermal current of 4‐6 µA@5 kΩ.

Imagery May Arise from Associations Formed through Sensory Experience: A Network of Spiking Neurons Controlling a Robot Learns Visual Sequences in Order to Perform a Mental Rotation Task. [PDF]
PLoS ONE, 2016 Mental imagery occurs "when a representation of the type created during the initial phases of perception is present but the stimulus is not actually being perceived." How does the capability to perform mental imagery arise?

Where are the gender differences? Male priming boosts spatial skills in women [PDF]
, 2008 The effects of gender stereotype activation by priming on performance in a spatial task were investigated among a mixed adult sample (including students) of 161 men and women (mean age=31.90) from Austria (Europe).
