Encompassing electrophysiological recordings and computational modeling data from gerbil medial superior olive (MSO) neurons, investigating subthreshold and spike resonance. The study characterizes resonance using impedance curves from sinusoidal stimuli and explores nonlinear voltage-dependent regimes. The data underpins findings on the role of the IKLT potassium current in neuronal resonance.
Encompassing simultaneous EEG and fMRI recordings from 16 participants performing a visuospatial attention task involving faces and landscapes. Created by Johanna M. Zumer and published in 2020, the data captures alpha band (8–13 Hz) oscillations and BOLD signals to map information gating from the visual cortex to the ventral stream.
Targeted patch-clamp recordings and synchronous local field potentials (LFPs) from PV and PYR neurons in the V1 cortex of awake mice. This 2020 dataset by Quentin Perrenoud captures subthreshold membrane potential dynamics during spontaneous and visually evoked gamma activity (30–80 Hz).
Rosy Southwell's 2020 study investigates whether predictable auditory patterns capture attention using behavioral and electroencephalography (EEG) experiments. The dataset includes data from experiments comparing responses to regular (REG) and random (RAND) sequences of tone pips. It provides neural and behavioral measures to test predictive coding accounts of attention in the auditory domain.
A collection of in vivo measurements of retinal neuron function in mice with photoreceptor degeneration (rd10). It documents restored visual responses in ganglion cell layer neurons expressing the red-shifted channelrhodopsin ChrimsonR over a six-week period following significant vision loss. The data was collected using high-resolution adaptive optics scanning light ophthalmoscopy to image fluorescence from the calcium sensor GCaMP6s.
Encompassing kinematic analysis of C. elegans behavior at submicron resolution, used to formulate and fit a stochastic neuronal model of random search. The model predicts behavioral effects of neuronal ablations and genetic perturbations. The data underpins a unified theoretical framework for understanding locomotion in this organism.
Experimental data from cell biological and pharmacological studies in squid axoplasm and primary cultured neurons reveals inhibition of fast axonal transport as a toxic effect of cellular prion protein. The research identifies casein kinase 2 activation as the molecular mechanism, involving phosphorylation of kinesin motor protein subunits. The dataset supports findings published by author Emiliano Zamponi in 2020.
Neuronal activity data from premanifest Hdh150 knock-in mice, used to study early Huntington's disease. The research assessed circuit dysregulation in the visual cortex and the effects of metformin treatment. Specific row counts and column details are not provided.
Comprising neurophysiological data from macaque prefrontal cortex neurons, investigating the relationship between resting-state autocorrelation structure and chosen value correlates during reward-guided decision making. The data was collected by Sean E. Cavanagh and published in 2020 under a CC0 license. Specific details on row count, column count, and file formats are unavailable.
2249 participants watched a crime video and were tested using either a US-style six-person simultaneous photo lineup or a UK-style nine-person sequential video lineup. The dataset supports analysis of discriminability and reliability in eyewitness identification procedures.
Continuous extracellular electrophysiology recordings and time-lapse imaging from hippocampal cell cultures, acquired over a period of up to 70 days. The data was generated using a custom benchtop perfusion system for simultaneous multimodal acquisition. It was created by Dirk Saalfrank and published in 2020.
Psychophysical data from a study on the crossmodal congruency effect (CCE) task, authored by Daniel Blustein and published in 2020. The dataset includes reaction time scores for congruent and incongruent trials, used to demonstrate a persistent learning effect that attenuates CCE scores with repeated task exposure.
Experimental data includes behavioral performance and event-related potential (ERP) recordings from participants performing visual search tasks. The study investigates the interaction between perceptual load and working memory guidance on selective attention. Data was collected by author Jinfeng Tan and published in 2020.
Comprising electroencephalographic (EEG) data from 20 right-handed healthy volunteers aged 21 to 32. It was collected to assess the interhemispheric effects of transcranial direct current stimulation (tDCS) on spectral power and event-related desynchronization (ERD) during motor imagery tasks.
A collection of structural MRI data from a cohort of 823 individuals, including 226 with schizophrenia, 227 with bipolar disorder, and 370 healthy comparison subjects. It was used to model the confounding effects of head motion on cortical thickness and surface area measurements. The analysis raises questions about the regional specificity of structural brain changes in these illnesses.
1,576 single neurons were recorded from the human amygdala and hippocampus across 65 sessions involving 42 patients. The dataset includes spike times, extracellular waveforms, behavioral responses, electrode locations, demographics, and visual stimuli from a recognition memory task. Subjects identified images as 'new' or 'old' using a 1-6 confidence scale.
70 studies from a systematic review examine cognitive function after spinal cord injury. The analysis investigates interactions with traumatic brain injury, psychological complaints, cardiovascular control, sleep apnea, injury level, and age. The review screened 2,481 studies to identify relevant quantitative reports.
Encompassing functional connectivity data from 831 participants in the Human Connectome Project, with findings cross-validated in an independent longitudinal dataset of 1,176 participants from the IMAGEN study. It examines differences in brain connectivity associated with smoking and drinking behaviors, linking them to specific brain regions like the orbitofrontal cortex. The data connects functional connectivity patterns in adolescence to future substance use at age 19.
Experimental data from a study testing strategic cooperation in humans, where informing participants their behavior would be known to groupmates tripled initial cooperation from 17% to 50%. The study was authored by Maxwell N. Burton-Chellew and published in 2020, designed to avoid confounding factors like learning about pay-offs or others' behavior during the game.
Electrophysiological recordings and mathematical model outputs investigating the interaction between the Na+/K+ pump and h-current in leech heart interneurons. Created by Daniel Kueh and updated in 2020, the data documents changes in neuronal bursting periods under pharmacological manipulations including monensin and strophanthidin. The collection includes both biological experimental results and synthetic data from a Na+ dynamics model.
