Two Visual Training Paradigms Associated with Enhanced Critical Flicker Fusion Threshold

open access: yesFrontiers in Psychology, 2016
Critical flicker fusion thresholds (CFFT) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases and are thought to underlie a number of visual processing skills, including reading ...

Orientation and Contrast Tuning Properties and Temporal Flicker Fusion Characteristics of Primate Superior Colliculus Neurons

open access: yesFrontiers in Neural Circuits, 2018
The primate superior colliculus is traditionally studied from the perspectives of gaze control, target selection, and selective attention. However, this structure is also visually responsive, and it is the primary visual structure in several species ...

From eyes’ microtremors to critical flicker fusion

open access: yesPLoS ONE
The critical flicker fusion threshold (CFFT) is the frequency at which a flickering light source becomes indistinguishable from continuous light. The CFFT is an important biomarker of health conditions, such as Alzheimer's disease and epilepsy, and is ...

Visuo-motor integration, vision perception and attention in mTBI patients. Preliminary findings.

open access: yesPLoS ONE, 2021
Patients with mild traumatic brain injuries (mTBI) often report difficulties in motor coordination and visuo-spatial attention. However, the consequences of mTBI on fine motor and visuo-motor coordination are still not well understood.

Medical image fusion: A survey of the state of the art [PDF]

open access: yes, 2014
Medical image fusion is the process of registering and combining multiple images from single or multiple imaging modalities to improve the imaging quality and reduce randomness and redundancy in order to increase the clinical applicability of medical ...

A multimodal approach connecting cortical and behavioural responses to the visual continuity illusion

open access: yesBrain and Neuroscience Advances
In their recently published study, Gil, Valente and Shemesh combined behaviour, functional magnetic resonance imaging, electroencephalography and causal interventions to establish and validate a cortical processing substrate underlying the transition ...

Flicker Fusion as a Typological Index of Nervous System ‘Reactivity’

open access: yes, 1983
Flicker fushion responses were determined under varying stimulus intensities for 43 subjects. A mathematical index of the responses was derived for each individual and compared to a single flicker fusion response. A correlation demonstrated independence

Comparison of Two Instrumental Assessment of Mental Fatigue

open access: yesInternational Journal of Occupational Hygiene, 2017
Mental fatigue (MF) is considered as a contributor factor in incident, even catastrophic one. Electroencephalography measurement has been the most acceptable method to assess MF by neurologists.
