Cerebral functional networks during sleep in young and older individuals

Scientific Reports, 2021
Even though sleep modification is a hallmark of the aging process, age-related changes in functional connectivity using functional Magnetic Resonance Imaging (fMRI) during sleep, remain unknown.

The benefit of the diffusion kurtosis imaging in presurgical evaluation in patients with focal MR-negative epilepsy

Scientific Reports, 2021
The effectivity of diffusion-weighted MRI methods in detecting the epileptogenic zone (EZ) was tested. Patients with refractory epilepsy (N=25) who subsequently underwent resective surgery were recruited.

Brain-anatomy image data set for problem solving associated with reversal error: Volumetric data

Data in Brief, 2023
Reversal Error (RE) is a common error in algebra problem solving. This error occurs when students recognize the information in the statement but make mistakes when translating some sentences from natural language to algebraic language, reversing the ...

Mapping and comparing fMRI connectivity networks across species

Communications Biology, 2023
Technical advances in neuroimaging, notably in fMRI, have allowed distributed patterns of functional connectivity to be mapped in the human brain with increasing spatiotemporal resolution.

White matter alterations in MR-negative temporal and frontal lobe epilepsy using fixel-based analysis

Scientific Reports, 2023
This study focuses on white matter alterations in pharmacoresistant epilepsy patients with no visible lesions in the temporal and frontal lobes on clinical MRI (i.e. MR-negative) with lesions confirmed by resective surgery.

Reward is not reward: Differential impacts of primary and secondary rewards on expectation, outcome, and prediction error in the human brain's reward processing regions

NeuroImage, 2023
According to their nature, rewarding stimuli are classified as primary (e.g., food, sex) and secondary (e.g., money) rewards. Neuroimaging studies have provided valuable insights in neural reward processing and its various aspects including reward ...

Increased fMRI connectivity upon chemogenetic inhibition of the mouse prefrontal cortex

Nature Communications, 2022
Pathological perturbation affects whole brain network activity. Here the authors show in mice that cortical inactivation unexpectedly results in increased fMRI connectivity between the manipulated regions and its direct axonal targets.

Brief neuronal afterdischarges in the rat hippocampus lead to transient changes in oscillatory activity and to a very long-lasting decline in BOLD signals without inducing a hypoxic state

NeuroImage, 2021
The effects of hippocampal neuronal afterdischarges (nAD) on hemodynamic parameters, such as blood-oxygen-level-dependent (BOLD) signals) and local cerebral blood volume (CBV) changes, as well as neuronal activity and metabolic parameters in the dentate ...
