BIAC Facilities

The Brain Imaging and Analysis Center (BIAC) encompasses more than 10,000 sq. ft. of new and newly-renovated space on the Duke University Medical Center campus. BIAC offices and image analysis laboratories are located in 3500 sq. ft. of newly renovated space in the Bell Research Building. The main offices of BIAC are located in 163 Bell and include the office of the Director, offices for the administrative staff, a conference room with a computer projector integrated with the BIAC network, and a copier and printer room. Offices for BIAC faculty, postdoctoral fellows, and graduate students are also located in Bell. The Bell Building BIAC space also contains an electronics shop, two image analysis labs, a computer/server room, a second conference room, and library and kitchen space. Adjacent to the Bell Research Building is the Duke North Hospital, which houses a new 7000 sq. ft addition for BIAC that contains two research-dedicated MRI suites, image analysis laboratories, a RF coil construction shop, and additional offices for faculty and students.

Time frequency toolbox for matlab

Time frequency toolbox for Matlab

Presentation
The Time-Frequency Toolbox is a collection of about 100 M-files, developed for the analysis of non-stationary signals using time-frequency distributions. It consists in groups of signal generation files, processing files and post-processing files (including visualization tools).

The toolbox contains numerous algorithms for time-frequency signal analysis, with special emphasis on quadratic energy distributions within Cohen's class and the affine class, including most recent developments based on reassignment.

ScienceDirect - Vision Research : Task constraints in visual working memory

Abstract
This paper examines the nature of visual representations that direct ongoing performance in sensorimotor tasks. Performance of such natural tasks requires relating visual information from different gaze positions. To explore this we used the technique of making task relevant display changes during saccadic eye movements. Subjects copied a pattern of colored blocks on a computer monitor, using the mouse to drag the blocks across the screen. Eye position was monitored using a dual-purkinje eye tracker, and the color of blocks in the pattern was changed at different points in task performance. When the target of the saccade changed color during the saccade, the duration of fixations on the model pattern increased, depending on the point in the task that the change was made. Thus different fixations on the same visual stimulus served a different purpose. The results also indicated that the visual information that is retained across successive fixations depends on moment by moment task demands. This is consistent with previous suggestions that visual representations are limited and task dependent. Changes in blocks in addition to the saccade target led to greater increases in fixation duration."

Change-blindness1,2 occurs when large changes are missed under natural viewing conditions because they occur simultaneously with a brief visual disruption, perhaps caused by an eye movement3,4, a flicker5, a blink6, or a camera cut in a film sequence7. We have found that this can occur even when the disruption does not cover or obscure the changes. When a few small, high-contrast shapes are briefly spattered over a picture, like mudsplashes on a car windscreen, large changes can be made simultaneously in the scene without being noticed. This phenomenon is potentially important in driving, surveillance or navigation, as dangerous events occurring in full view can go unnoticed if they coincide with even very small, apparently innocuous, disturbances. It is also important for understanding how the brain represents the world.
