The influence of visual landscape on the free flight behavior of the fruit fly Drosophila melanogaster [PDF]

, 2002
To study the visual cues that control steering behavior in the fruit fly Drosophila melanogaster, we reconstructed three-dimensional trajectories from images taken by stereo infrared video cameras during free flight within structured visual landscapes ...

Aging increases compensatory saccade amplitude in the video head impulse test

Frontiers in Neurology, 2016
Objective: Rotational vestibular function declines with age resulting in saccades as a compensatory mechanism to improve impaired gaze stability. Small reductions in rotational vestibulo-ocular reflex (VOR) gain that would be considered clinically ...

What works in internal alternative provision? A salutogenic analysis

British Educational Research Journal, EarlyView.
Abstract Schools across England are setting up ‘internal alternative provision’ to meet the social, emotional and mental health needs of increasing numbers of pupils at risk of suspension, exclusion and absence. However, there is little guidance about what good practice looks like.

Functional imaging reveals rapid reorganization of cortical activity after parietal inactivation in monkeys [PDF]

, 2012
Impairments of spatial awareness and decision making occur frequently as a consequence of parietal lesions. Here we used event-related functional MRI (fMRI) in monkeys to investigate rapid reorganization of spatial networks during reversible ...

Exploring age-related changes in saccades during cognitive tasks in healthy adults

Frontiers in Behavioral Neuroscience
IntroductionAlthough eye movements such as saccades are related to internal cognitive processes and are independent of visual processing, few studies have investigated whether non-visual cognitive tasks simultaneously affect horizontal and vertical ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The Influence of the Number of Decision Branches on Saccade Latency

i-Perception, 2011
Saccades are rapid eye movements whose function is to bring new objects of interest to the fovea. A saccade is a ballistic movement: once it has begun, its trajectory cannot be altered. A single saccade takes about 150–200 ms to plan and execute (saccade

Error inconsistency does not generally inhibit saccadic adaptation: Support for linear models of multi‐gainfield adaptation

Physiological Reports, 2022
This study examined saccade adaptation induced by intrasaccadic target steps (ITS). By manipulating the ITS, we investigated potential effects of the consistency of the feedback error on saccade adaptation, which would provide evidence against the ...

Development and Retrospective Application of Novel Outcome Measure: Sturge–Weber Syndrome Acute Crisis (SWAC) Index

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Objective Sturge–Weber syndrome (SWS) symptoms frequently overlap in neurological acute crises (ACs) presenting with seizures, stroke‐like episodes (SLE), and headaches. Recent efforts to develop a prospective drug trial highlighted the need for a new outcome measure capable of quantifying these symptoms during an SWS AC.
