A brief thought can modulate activity in extrastriate visual areas: Top-down effects of refreshing just-seen visual stimuli
Current models of executive function hold that the internal representations of stimuli used during reflective thought are maintained in the same posterior cortical regions initially activated during perception, and that activity in such regions is modulated by top-down signals originating in prefrontal cortex. In an event-related functional magnetic resonance imaging study, we presented partici...
متن کاملVisual stimuli modulate frontal oscillatory rhythms in a cortically blind patient: Evidence for top-down visual processing.
OBJECTIVE We investigated neuronal correlates of faces versus non-faces processing in a cortically blind patient (TN) and a group of healthy age-matched controls in order to test electrophysiological correlates of the processing of pertinent stimuli in this patient. METHODS An EEG paradigm was used, in which intact and scrambled faces were displayed on a screen. First, time-frequency transfor...
متن کاملAn fMRI study of human visual cortex in response to spatiotemporal properties of visual stimuli
ABSTRACT Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF). Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd. Results: Average percentage BOLD signa...
متن کاملEffects of visual deprivation on epileptic activity in mature rat visual cortex
Effects of visual deprivation on the induction of epileptiform activity were studied in layer II/III of mature rat primary visual cortex. Field potentials were evoked by stimulation of layer IV in slices from control and dark-reared (OR) rats. Picrotoxin (PTX)-induced epileptic activity was characterized by spontaneous and evoked epileptic field potentials (EFPs). The results showed that OR s...
متن کاملVisual acuity with brief stimuli.
INTRODUCTION ALTHOUGH the visual acuity of the eye has been often investigated, it has not yet been examined very fully in conditions of limited exposure time. The only known previous investigations in this field are those of Graham and Cook (1937), and Niven and Brown (1944), apart from a similar investigation on the somewhat analogous problem of intensity discrimination at short exposure time...
