Hot off the Press: Temporal Expectation Enhances Contrast Sensitivity by Phase Entrainment of Low-Frequency Oscillations in Visual Cortex 28 February 2013Can we use temporal information to enhance perceptual processing of events happening at predicted time points? This is the question addressed in a new study published this week in the Journal of Neuroscience. In this study we combined a psychophysical task with electrophysiological recordings to test whether the entrainment of brain oscillations to rhythmic events modulates the contrast gain during visual processing. The results indicated that the phase entrainment of low-frequency oscillations in visual cortex serve as an important and flexible mechanism for sensory selection. The results build on recent interest in predictive mechanisms in cognition, the role of oscillatory network dynamics in perception and cognition, and a renaissance of research into how the brain can use time to enhance information processing.

Do you want to know more about dementia? 20 February 2013The Dementia Awareness Public Open Day organised by the local Alzheimer's Research UK network will be held on Saturday 16th March 2013 at the John Radcliffe Hospital 10:00am - 1:00pm in Lecture Theatre 2, Academic Centre in the grounds of the John Radcliffe Hospital, Headington, Oxford What can we learn from the human brain to better understand the mechanism of disease progression? What is the relationship between vascular and neurodegenerative disease? How do these diseases affect human cognitive ability, and how could increasing physical and mental activity potentially improve cognitive health and prevent cognitive decline?
