Parietal Area VIP Neuronal Responses to Heading Stimuli Are Encoded in Head-Centered Coordinates
The ventral intraparietal area (VIP) is a multimodal parietal area, where visual responses are brisk, directional, and typically selective for complex optic flow patterns. VIP thus could provide signals useful for visual estimation of heading (self-motion direction). A central problem in heading estimation is how observers compensate for eye velocity, which distorts the retinal motion cues upon...
متن کاملHeading encoding in the macaque ventral intraparietal area (VIP).
We recorded neuronal responses to optic flow stimuli in the ventral intraparietal area (VIP) of two awake macaque monkeys. According to previous studies on optic flow responses in monkey extrastriate cortex we used different stimulus classes: frontoparallel motion, radial stimuli (expansion and contraction) and rotational stimuli (clockwise and counter-clockwise). Seventy-five percent of the ce...
متن کاملThe responses of horses to predator stimuli
It is not known whether the instincts of wild horses have remained strong during their centuries of domestication. Knowledge of this matter would give riders the opportunity to know more about the behavior of horses and consequently about safety for both horses and riders. In this current research, we studied the behavior of fifteen Caspian miniature horses of different ages and sexes using sti...
متن کاملMacaque ganglion cell responses to probe stimuli on modulated backgrounds.
In the natural environment, visual targets have to be detected and identified on changing backgrounds. Here, responses of parasol (magnocellular) ganglion cells to probes on modulated backgrounds are described. At low frequency, the adaptation level of the background influences the probe response, but with increasing frequency there is a strong interaction with the response to the background pe...
متن کاملThe responses of VIP neurons are sufficiently sensitive to 1 support heading judgments
35 The ventral intraparietal area (VIP) of the macaque monkey is thought to be 36 involved in judging heading direction based on optic flow. We recorded neuronal 37 discharges in VIP while monkeys were performing a two-alternative, forced-choice 38 heading discrimination task to relate quantitatively the activity of VIP neurons to 39 monkeys’ perceptual choices. Most VIP neurons were responsive...
