2000a). Memory activity of LIP neurons for sequential eye movements simulated with neural networks
- Journal of Neurophysiology
"... neurons for sequential eye movements simulated with neural net-works. J Neurophysiol 84: 651–665, 2000. Many neurons in macaque lateral intraparietal cortex (LIP) maintain elevated activity induced by visual or auditory targets during tasks in which monkeys are required to withhold one or more plann ..."

Response to Comment on “In Monkeys Making Value-Based Decisions, LIP Neurons Encode Cue Salience and Not Action Value”
"... Newsome et al. question neither our key result, that large-penalty cues elicited stronger responses than small-penalty cues, nor our key conclusion, that neurons early in the trial signaled cue salience and not action value. Instead, they focus on subsequent neuronal activity. The patterns of delay- ..."

-period activity that they note can be explained by reference to experimental methodology. The stated goal of our study (1) was to testa specific hypothesis: that lateral intrapa-rietal (LIP) neurons mediate value-based decisions by signaling early in the trial—before the decision—the values of the outcomes asso

"... We present a biologically plausible spiking net-work model of visual motion processing and per-ceptual decision making, independent of the number of choice alternatives. As an application we simulate the two-alternative forced choice (2AFC) task. The integration of local dot velocities over time pro ..."

aspects of single neuron and psychometric data from monkeys. Fewer choices lead to faster decisions since the minimum detectable difference in signal among a few alternatives is greater vs distribution among many. The model works with n dimensions, continuous choices and any integrate
Response of Neurons in the Lateral Intraparietal Area during a Combined Visual Discrimination Reaction Time Task
- Journal of Neuroscience
, 2002
"... Decisions about the visual world can take time to form, especially when information is unreliable. We studied the neural correlate of gradual decision formation by recording activity from the lateral intraparietal cortex (area LIP) of rhesus monkeys during a combined motion-discrimination reaction-t ..."

During the period of decision formation, the epoch between onset of visual motion and the initiation of the eye movement response, LIP neurons underwent ramp-like changes in their discharge rate

Modulation of LIP activity by predictive auditory and visual cues
- Cerebral Cortex
, 2004
"... The lateral intraparietal area (area LIP) contains a multimodal repre-sentation of extra-personal space. To further examine this represen-tation, we trained rhesus monkeys on the predictive-cueing task. During this task, monkeys shifted their gaze to a visual target whose location was predicted by t ..."

for both auditory cues and visual cues. Despite the fact that the monkeys used auditory and visual cues in a similar fashion, LIP neurons responded more to visual cues than to auditory cues. This modality-dependent activity was also seen during auditory and visual memory-guided saccades but to a
Progression in neuronal processing for saccadic eye movements from parietal cortex area LIP to superior colliculus

Motor intention activity in the macaque’s lateral intraparietal area. I. Dissociation of motor plan from sensory memory
- Journal of Neurophysiology
, 1996
"... posterior parietal cortex (PPC) contains neurons that are active during saccadic eye movements. These neurons ’ activity includes visual and saccade-related components. These responses are spa-tially tuned and the location of a neuron’s visual receptive field (RF) relative to the fovea generally ove ..."

When a delay is imposed between the presentation of a visual stimulus and a saccade made to its location (memory saccade task), many LIP neurons maintain elevated activity during the delay (memory activ-ity, M), which
Temporal structure in neuronal activity during working memory in macaque parietal cortex,”
- Nature Neuroscience,
, 2002
"... The neural basis of working memory is typically studied in non-human primates by recording activity during delayed response tasks 1 . Cue-selective elevations in mean firing rates are found during the delay period in many brain areas using different versions of these tasks Temporally correlated ne ..."

neuronal activity in the form of reverberations is proposed to be important to cognitive processing 13,14 . However, temporal structure is not captured by measures of mean activity, such as the firing rate, so measures of the variance, such as the spectrum, are required. We characterize temporal structure
Microstimulation of macaque area LIP affects decision-making in a motion discrimination task.
- Nat. Neurosci.
, 2006
"... A central goal of cognitive neuroscience is to elucidate the neural mechanisms underlying decision-making. Recent physiological studies suggest that neurons in association areas may be involved in this process. To test this, we measured the effects of electrical microstimulation in the lateral intr ..."

. These results demonstrate that the discharge of LIP neurons is causally related to decision formation in the discrimination task. Much progress has been made in understanding the neurobiology of decision-making by tracing the neural events that link sensory processing to a choice of action in monkeys 1
