Slow brain potentials in a visual-spatial memory task: topographic distribution and inter-laboratory consistency.
Slow brain electrical potentials (SPs) were investigated in a visual-spatialmemory task. Two issues were addressed: (1) the nature and topographic distribution of the potentials obtained under such conditions; and (2) the consistency of the SPs when recorded in six identically configured laboratories. Fifteen young male subjects were studied at each laboratory (total n = 90). The paradigm entai...
متن کاملHow Visual Information Affects a Spatial Task
To examine the information content of mental representations of three-dimensional objects, 21 participants performed a mental rotation task with the classic Shepard and Metzler (1971) figures. We compared conditions in which the figures were monochromatic, a condition in which they were colored consistently, and a condition in which they were colored inconsistently. Color affected performance o...
متن کاملA spatial oculomotor memory-task performance produces a task-related slow shift in human electroencephalography.
Electroencephalographic (EEG) deflections in humans related to the performance of memory-guided saccades were studied in this work. The EEG deflections were recorded during 2 spatial oculomotor delayed response tasks in which the subject was instructed to make a saccade either to the right or to the left depending on the spatial location of the cue which had been shown in the beginning of the d...
متن کاملLearning selective top-down control enhances performance in a visual categorization task Top-down control in learning a categorization task
We model the putative neuronal and synaptic mechanisms involved in learning a visual categorization task, taking inspiration from single-cell recordings in inferior temporal cortex (ITC). Our working hypothesis is that learning the categorization task involves both bottom-up, ITC to pre-frontal cortex (PFC), and top-down (PFC to ITC) synaptic plasticity, and that the latter enhances the selecti...
متن کاملTraining in a ballistic task but not a visuomotor task increases responses to stimulation of human corticospinal axons.
Short periods of training in motor tasks can increase motor cortical excitability. This study investigated whether changes also occur at a subcortical level. Subjects trained in ballistic finger abduction or visuomotor tracking. The right index finger rotated around the metacarpophalangeal (MCP) joint in a splint. Surface EMG was recorded from the first dorsal interosseous. Transcranial magneti...
