Action video game playing is associated with improved visual sensitivity, but not alterations in visual sensory memory.
(Atten Percept Psychophys, 2013-08)Action video game playing has been experimentally linked to a number of perceptual and cognitive improvements. These benefits are captured through a wide range of psychometric tasks and have led to the proposition that action ... -
Age-related preservation of top-down control over distraction in visual search.
(Experimental aging research, 2010-07)Visual search studies have demonstrated that older adults can have preserved or even increased top-down control over distraction. However, the results are mixed as to the extent of this age-related preservation. The present ... -
Auditory signals evolve from hybrid- to eye-centered coordinates in the primate superior colliculus.
(Journal of neurophysiology, 2012-07)Visual and auditory spatial signals initially arise in different reference frames. It has been postulated that auditory signals are translated from a head-centered to an eye-centered frame of reference compatible with the ... -
Brain circuits for the internal monitoring of movements.
(Annu Rev Neurosci, 2008)Each movement we make activates our own sensory receptors, thus causing a problem for the brain: the spurious, movement-related sensations must be discriminated from the sensory inputs that really matter, those representing ... -
Chemogenetics-mediated acute inhibition of excitatory neuronal activity improves stroke outcome.
(Experimental neurology, 2020-04)<h4>Background and purpose</h4>Ischemic stroke significantly perturbs neuronal homeostasis leading to a cascade of pathologic events causing brain damage. In this study, we assessed acute stroke outcome after chemogenetic ... -
Cross-hemispheric collaboration and segregation associated with task difficulty as revealed by structural and functional connectivity.
(J Neurosci, 2015-05-27)Although it is known that brain regions in one hemisphere may interact very closely with their corresponding contralateral regions (collaboration) or operate relatively independent of them (segregation), the specific brain ... -
Delay activity of saccade-related neurons in the caudal dentate nucleus of the macaque cerebellum.
(J Neurophysiol, 2013-04)The caudal dentate nucleus (DN) in lateral cerebellum is connected with two visual/oculomotor areas of the cerebrum: the frontal eye field and lateral intraparietal cortex. Many neurons in frontal eye field and ... -
Distress tolerance to auditory feedback and functional connectivity with the auditory cortex.
(Psychiatry research. Neuroimaging, 2018-12)Distress tolerance is the capacity to withstand negative affective states in pursuit of a goal. Low distress tolerance may bias an individual to avoid or escape experiences that induce affective distress, but the neural ... -
Drivers from the deep: the contribution of collicular input to thalamocortical processing.
(Prog Brain Res, 2005)A traditional view of the thalamus is that it is a relay station which receives sensory input and conveys this information to cortex. This sensory input determines most of the properties of first order thalamic neurons, ... -
Emotion-attention network interactions during a visual oddball task.
(Brain Res Cogn Brain Res, 2004-06)Emotional and attentional functions are known to be distributed along ventral and dorsal networks in the brain, respectively. However, the interactions between these systems remain to be specified. The present study used ... -
Frontal eye field neurons with spatial representations predicted by their subcortical input.
(J Neurosci, 2009-04-22)The frontal eye field (FEF) is a cortical structure involved in cognitive aspects of eye movement control. Neurons in the FEF, as in most of cerebral cortex, primarily represent contralateral space. They fire for visual ... -
Health and function of participants in the Long Life Family Study: A comparison with other cohorts.
(Aging (Albany NY), 2011-01)Individuals from families recruited for the Long Life Family Study (LLFS) (n= 4559) were examined and compared to individuals from other cohorts to determine whether the recruitment targeting longevity resulted in a cohort ... -
Imagery and retrieval of auditory and visual information: neural correlates of successful and unsuccessful performance.
(Neuropsychologia, 2011-06)Remembering past events - or episodic retrieval - consists of several components. There is evidence that mental imagery plays an important role in retrieval and that the brain regions supporting imagery overlap with those ... -
Improvement in visual search with practice: mapping learning-related changes in neurocognitive stages of processing.
(J Neurosci, 2015-04-01)Practice can improve performance on visual search tasks; the neural mechanisms underlying such improvements, however, are not clear. Response time typically shortens with practice, but which components of the stimulus-response ... -
Inhibition-Induced Forgetting Results from Resource Competition between Response Inhibition and Memory Encoding Processes.
(J Neurosci, 2015-08-26)UNLABELLED: Response inhibition is a key component of executive control, but its relation to other cognitive processes is not well understood. We recently documented the "inhibition-induced forgetting effect": no-go cues ... -
Learning from falling.
(Child Dev, 2006-01)Walkers fall frequently, especially during infancy. Children (15-, 21-, 27-, 33-, and 39-month-olds) and adults were tested in a novel foam pit paradigm to examine age-related changes in the relationship between falling ... -
Looking at the ventriloquist: visual outcome of eye movements calibrates sound localization.
(PloS one, 2013-01)A general problem in learning is how the brain determines what lesson to learn (and what lessons not to learn). For example, sound localization is a behavior that is partially learned with the aid of vision. This process ... -
Mapping the structure of perceptual and visual-motor abilities in healthy young adults.
(Acta Psychol (Amst), 2015-05)The ability to quickly detect and respond to visual stimuli in the environment is critical to many human activities. While such perceptual and visual-motor skills are important in a myriad of contexts, considerable variability ... -
Neuronal adaptation caused by sequential visual stimulation in the frontal eye field.
(J Neurophysiol, 2008-10)Images on the retina can change drastically in only a few milliseconds. A robust description of visual temporal processing is therefore necessary to understand visual analysis in the real world. To this end, we studied subsecond ... -
Neuronal correlates of metacognition in primate frontal cortex.
(Neuron, 2012-08-09)Humans are metacognitive: they monitor and control their cognition. Our hypothesis was that neuronal correlates of metacognition reside in the same brain areas responsible for cognition, including frontal cortex. Recent ...
