Lowet, E., Roberts, M. J., Gips, B. C. I., De Weerd, P., & Peter, A. (2017) eLife, 2017, 6:e26642. Abstract Gamma-band synchronization coordinates brief periods of excitability in oscillating neuronal populations to optimize information transmission during sensation and cognition. Commonly, a stable, shared frequency over time is considered a condition […]
Lowet, E., Roberts, M. J., Bosman, C. A., Fries, P., & De Weerd, P. (2015) European Journal of Neuroscience, 2015, 43(10): 1286-1296. Abstract Neuronal gamma-band synchronization (25-80 Hz) in visual cortex appears sustained and stable during prolonged visual stimulation when investigated with conventional averages across trials. However, recent studies in macaque […]
Roberts, M. J., Lowet, E., Brunet, N. M., Ter Wal, M., Tiesinga, P., Fries, P., & De Weerd, P. (2013) Neuron, 78(3), 523-536. Abstract Current theories propose that coherence of oscillatory brain activity in the gamma band (30-80 Hz) constitutes an avenue for communication among remote neural populations. However, reports documenting […]
Vallès, A., Boender, A. J., Gijsbers, S., Haast, R. A., Martens, G. J., & de Weerd, P. (2011) The Journal of Neuroscience, 31(16), 6140-6158. Abstract Because of its anatomical organization, the rodent whisker-to-barrel system is an ideal model to study experience-dependent plasticity. Manipulation of sensory input causes changes in the […]
Been, M., Jans, B., & De Weerd, P. (2011) The Journal of Neuroscience, 31(42), 14944-14951. Abstract Perceptual skills improve with daily practice (Fahle and Poggio, 2002; Fine and Jacobs, 2002). Practice induces plasticity in task-relevant brain regions during an “offline” consolidation period thought to last several hours, during which initially […]
Jans, B., Peters, J. C., & De Weerd, P. (2010) Psychological review, 117(2), 637. Abstract Although in traditional attention research the focus of visual spatial attention has been considered as indivisible, many studies in the last 15 years have claimed the contrary. These studies suggest that humans can direct their […]
Kastner, S., Pinsk, M. A., De Weerd, P., Desimone, R., & Ungerleider, L. G. (1999) Neuron, 22(4), 751-761. Abstract When subjects direct attention to a particular location in a visual scene, responses in the visual cortex to stimuli presented at that location are enhanced, and the suppressive influences of nearby […]
DeWeerd, P., Peralta, M. R., Desimone, R., & Ungerleider, L. G. (1999) Nature neuroscience, 2(8), 753-758. Abstract Many objects in natural visual scenes compete for attention. To identify the neural mechanisms necessary for visual attention, we made restricted lesions, affecting different quadrants of the visual field but leaving one quadrant […]
