This dataset comprises electroencephalography (EEG) recordings from 50 healthy control participants performing a reinforcement learning task under two mood conditions: sad mood manipulation (n=25) and neutral mood manipulation (n=25). The task included training and testing phases adapted from established reinforcement learning paradigms. Data were collected between 2019-2021 at the Cognitive Rhythms and Computation Lab at the University of New Mexico to investigate the effects of mood state on learning and decision-making processes.

This dataset comprises electroencephalography (EEG) recordings from 13 participants performing semantic imagination and perception tasks across visual and auditory modalities. Participants were presented with stimuli from three semantically dissimilar categories (guitar, flower, penguin) in pictorial, orthographic, and auditory formats. The dataset includes raw, preprocessed, and epoched EEG data acquired using a 124-channel ANT-Neuro system, providing a resource for investigating neural correlates of semantic processing and cross-modal perception.

This dataset comprises two reversal learning tasks designed to investigate differential neural processing of reward gain and punishment avoidance. Participants performed parallel tasks using distinct reinforcers: monetary reward (gain/non-gain outcomes) and primary threat avoidance (noise burst avoidance/application), with noise intensity individually titrated to match subjective value of monetary rewards. The dataset enables investigation of how the brain differentially encodes appetitive versus aversive learning contingencies.

A large-scale Spanish EEG dataset comprising 60 sessions from 56 healthy participants recorded using 64-channel EEG during speech perception and silent speech production tasks. Participants listened to and silently repeated 30 daily-use Spanish sentences. This dataset enables development of subject-independent deep neural network models for perceived sentence classification, with applications to speech decoding and neuroprosthetics for individuals with speech disorders.

This dataset contains neuroimaging data from a cued recall task investigating sustained neural representations of personally familiar people and places. Participants were cued to recall specific individuals and locations while MEG data were recorded, enabling investigation of how the brain maintains and represents autobiographical memories of social and spatial information.

This dataset comprises magnetoencephalography (MEG) recordings of auditory single word recognition in human subjects. Participants listened to isolated words while neural activity was recorded, providing insights into the temporal dynamics of auditory word comprehension. The dataset is described in Gaston et al. (2022) 'Auditory word comprehension is less incremental in isolated words' published in Neurobiology of Language. The dataset includes raw MEG data, stimulus information, and associated metadata organized according to the Brain Imaging Data Structure (BIDS) standard. This is a NEMAR-converted version of OpenNeuro dataset ds004276.

This dataset comprises electroencephalography (EEG) recordings from 21 participants performing a dynamic ship-steering task under four noise conditions: no noise, environmental noise only, controller noise only, and combined environmental and controller noise. Participants controlled a centrally presented rotating arrow to maintain target orientation while experiencing manipulated levels of environmental and controller noise. The task employed unstable dynamics based on the pole-and-cart problem, with performance measured by proximity to target and crash avoidance. This dataset provides rich behavioral and neural data for investigating decision-making, motor control, and adaptation under uncertainty. Note: Participant 12 should be excluded from event-locked analyses due to bad triggers (trigger cable was partially disconnected). The reaction time for the first button press in each round is not recorded in the standard event markers but is available in the participantActions column.

This dataset contains electroencephalography (EEG) recordings from 21 participants performing a continuous feedback prediction task. Participants learned to predict the final level of an animated rising bar under varying conditions of outcome predictability (highly predictable, somewhat predictable, and unpredictable), with performance feedback provided through point rewards. The dataset includes behavioral responses, stimulus timing information, and trigger codes for experimental events, enabling investigation of neural correlates of prediction, feedback processing, and learning under uncertainty.

This dataset comprises neuroimaging data from two auditory experiments investigating the cortical encoding of sound source elevation in human subjects. Participants were presented with noise bursts from loudspeakers positioned at various elevations while undergoing behavioral testing and neural recording. The dataset includes localization tests, a deviant detection task (Experiment 1), and a one-back working memory task (Experiment 2), providing insights into how the human brain processes spatial auditory information.

This dataset comprises electroencephalography (EEG) recordings from 16 participants viewing object images presented at eight different 2-D rotations in rapid visual streams at two presentation rates (5 Hz and 20 Hz). The study investigates rotation-tolerant neural representations and their temporal dynamics during high-level object processing, providing insights into how the visual system encodes object identity invariant to viewpoint changes.
