The investigators collected simultaneous recordings using multi-channel electrode arrays attached to the prearcuate gyrus of macaque monkeys who performed a direction discrimination task with fixed stimulus duration. In the study, 96-channel multielectrode arrays were used to record from neural populations in area 8Ar of the prearcuate gyrus of three macaque monkeys, while they performed a direction...

This dataset assesses the influence of timescale on the processing of visual stimuli. Following training sessions where they reached at least 76% accuracy, five human subjects (four male and one female) were presented with the following task: brief samples of a contrast pattern were presented on screen for 200 ms, followed by a pause before the subjects were prompted to match the samples to one of...

This dataset presented results from psychophysics and modeling that supports the use of image statistics heuristics in the judgement of metallicity. To investigate visual features associated with the interpretation of metallic objects, five practiced participants (aged 23 to 28 years old) with normal color vision and normal or corrected-to-normal visual acuity were recruited to perform a conjoint-measurement...

To investigate the relationship between two behavioral markers of arousal (pupil size and brain activity) and perceptual decision-making, recordings were simultaneously obtained on pupil size and brain activity using magnetoencephalography (MEG). Data was collected from a total of 24 adult participants during eyes-open rest sessions and a visual perceptual decision-making task. Two 5-minute rest...

The investigators collected behavioral data from two macaque monkeys (M1 and M2) who were presented with a direction discrimination task with post-decision wagering. These monkeys received prior training to report the net direction of motion of a set of randomly moving dots. In each trial, the subject fixed their gaze on an initial fixation point, then red dots would appear on the periphery of the...

Using a Y-shaped maze, several experiments were developed to assess conditions of associative learning among fruit fly larvae. Prior to the start of the experiments, some fruit fly larvae were fed a diet of all-trans-retinal (ATR), which is a co-factor for csChrimson activation (eliciting escape behavior in flies which perceive red light). A subgroup of larvae who were fed ATR also received cycloheximide...

The subthalamic nucleus (STN) has been involved in adjusting the decision bound to prevent impulsivity during difficult decisions. This study incorporated model-based and model-free approaches to assess that the STN raises the decision bound, a process impaired by deep brain stimulation (DBS). They recruited eight male and female human subjects that were being treated for Parkinson's disease with bilateral...

Between July 25, 2016 and December 22, 2017, investigators conducted a longitudinal study with repeated panel surveys to understand attitudes and behaviors related to the emerging Zika virus among women of child-bearing age. Study participants included a representative survey sample of US women aged 18 to 45 years old who had participated in a related study about perceptions of the Zika virus (n=75)...

This study investigated how psychophysical reverse correlation may be used to understand the sensory mechanisms and decision-making processes underlying goal-directed behavior. The investigators used simulation modeling to build variations of a drift diffusion model (DDM) to develop a quantitative measure of psychophysical kernels on the integration of sensory input over time (non-decision time) until...

The investigators conducted experiments with seven macaque monkeys to understand how measures of neural activity in the lateral intraparietal (LIP) cortex corresponded with decision-making as they performed different tasks: a motion discrimination task and two variations on a novel face categorization task where subjects reported the faces' species or expression. They found that neuron firing rates...
