Neuromagnetic Response to Body Motion and Brain Connectivity

Journal of Cognitive Neuroscience, 2009
Abstract Visual detection of body motion is of immense importance for daily-life activities and social nonverbal interaction. Although neurobiological mechanisms underlying visual processing of human locomotion are being explored extensively by brain imaging, the role of structural brain connectivity is not well understood.

Motion Blurring with Decaying Detector Response

Applied Optics, 1971
The spread function and optical transfer function associated with image motion relative to the recording medium are derived and generalized to cover media whose response changes with time. Specific expressions are derived for an exponentially decaying response and three types of image motion: linear, sinusoidal, and random walk.

The Effects of Complex Stapes Motion on the Response of the Cochlea

Otology & Neurotology, 2008
The piston-like motion of the stapes footplate is the only effective stimulus to the cochlea, and rocking-like stapes motions have no effect on hearing.Studies of the vibration of the stapes in response to acoustic stimulation of the normal ear have revealed a complex movement pattern of its footplate.

Response theory and reduced equations of motion

Physical Review E, 2009
Nonlinear response theory for a relaxation experiment is used to derive classical and quantum-mechanical equations of motion for reduced distribution functions or density matrices, respectively. The classical equations are linear, but the quantum ones are not. The results are analyzed in the weak-coupling and separation-of-time-scales limits.

Performance and Autonomic Responses During Motion Sickness

Human Factors: The Journal of the Human Factors and Ergonomics Society, 2009
Objective: The aim of the study was to investigate how motion sickness, triggered by an optokinetic drum, affects short-term memory performance and to explore autonomic responses to perceived motion sickness. Background: Previous research has found that motion sickness decreases performance, but it is not known how short-term memory in particular is ...

Response priming with apparent motion primes

Psychological Research, 2012
Response priming refers to the finding that a prime stimulus preceding a target stimulus influences the response to the following target stimulus. Typically, responses are faster and more accurate if the prime calls for the same response as the target (i.e., compatible trials), as compared with the situation where primes and targets trigger different ...

Cortical responses to object-motion and visually-induced self-motion perception

Cognitive Brain Research, 2001
We investigated the spatiotemporal cortical dynamics during the perception of object-motion and visually-induced self-motion perception in six normal subjects, using a 143-channel neuromagnetometer. Object-motion specific tasks evoked early transient activity over the right temporooccipital cortex, while self-motion perception, or vection, additionally

Visual responses to changing size and to sideways motion for different directions of motion in depth: Linearization of visual responses

Journal of the Optical Society of America, 1980
This psychophysical study explored one possible basis for visually judging the direction of motion in depth. We propose that the changing-size channels precisely compute the algebraic difference between the velocities of opposite edges of a target, thus extracting the velocity component Vz along a line through the eye independent of the trajectory of ...

Strong Motion Response Spectra

Seismological Research Letters, 1971
Empirical equations derived from explosion data compare well with earthquake measurements. Maximum earth motion in cm, cm/sec, and gravity units, body wave earthquake magnitude, and distance in km, are included in the functions: a = 3.04 × 10 0.74 m − 4 R − 1.4 v = 4.06 × 10 0.88 m − 3 R − 1.5
