Sources and Targets of Trophic Factors in the Avian Locus Coeruleus and Oculomotor System
… of neurotrophic factors in the avian nervous system. How trophic signals are transmitted in the nervous system is a key question in neuroscience research. Cells in the nervous system can retrieve trophic signals by two distinct routes. One is through axonal transport (wiring transmission), …

Neuromuscular junction formation in Extraocular muscles of embryonic mice
Proper functioning of the visual system depends on correct functioning of the oculomotor system. When the oculomotor system functions correctly, cranial nerves III, IV, and VI migrate to and properly innervate the appropriate extraocular muscles. If proper innervation does not take place, …

Multiple spatial memories in the brain : decoding and modification using microstimulation
… to sequential motor outputs, we have used the oculomotor system as a model. We trained monkeys to remember the location of two spatial cues over a brief delay, and then make two eye movements to the remembered locations in the order that they appeared. We explored the role of two different …

A LabVIEW program to obtain the initiating component of a vergence eye movement in an open-loop experiment
The vergence oculomotor system is used in viewing objects moving in depth, such as when a baseball player tracks a ball moving towards him. It is composed of two components according to the Dual Mode Theory; a fast preprogrammed initiating component and a slow feedback-controlled sustaining …

Anticipatory smooth eye movements elicited by cues
… experiments tested the sensitivities of the oculomotor system to cue properties, namely, effectiveness in overwriting past history of target motion, cue delay, cue removal, and cue validity. The barrier cue produced faster anticipatory eye movements than the arbitrary cues, and overwrite the …

Using Eye Movements to Establish a Normative Database of Control Participants Across the Lifespan
… control that occur across the lifespan. The oculomotor system is an ideal model to probe cognitive function through the analysis of saccadic eye movements. We used a video-based eye tracker capable of measuring various saccade metrics on an interleaved pro- and anti-saccade task in healthy …

The determinants of auditory distraction during reading: an eye-movement investigation.
… was likely due to saccadic inhibition of the oculomotor system. Taken together, the present results demonstrate that eye-movements during reading can reveal subtle auditory distraction effects that may not be detected in measures of comprehension accuracy and that they can give important …

The Role of Parvalbumin Interneurons in Mouse Primary Visual Cortex during Visual Discrimination and Perceptual Learning
… areas (Diaz et al., 2017), and the oculomotor system (Kwon et al., 2013), challenges this view. Indeed, mice are extremely flexible in generalizing the task rule and adapt their behaviour over days to successfully discriminate previously inexperienced stimuli using a categorization …

The Effects of Parkinson's on Fixational Stability
Parkinson's disease (PD) is a progressive, neurological movement disorder. The stability of eye movements in PD is not well understood but many patients report difficulty doing tasks that require stabilized fixation and gaze. The ability to stabilize an image on the retina is critical is acquiring …

Estudio de la señal electrooculográfica y su aplicación a sistemas médicos asistenciales
… utiliza habitualmente para investigar el sistema oculomotor humano debido a que el movimiento de los ojos revela signos críticos de trastornos neurológicos. Además de las aplicaciones médicas descritas es posible utilizar las señales EOG para desarrollar sencillos interfaces hombre-máquina (HCI, …
