Nonparametric permutation tests for functional neuroimaging: A primer with examples [PDF]

open access: bronzeHuman Brain Mapping, 2001
Requiring only minimal assumptions for validity, nonparametric permutation testing provides a flexible and intuitive methodology for the statistical analysis of data from functional neuroimaging experiments, at some computational expense. Introduced into

Cerebral functional networks during sleep in young and older individuals

open access: yesScientific 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

open access: yesScientific 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.

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

open access: yesScientific 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.

Increased fMRI connectivity upon chemogenetic inhibition of the mouse prefrontal cortex

open access: yesNature 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.

Individual Differences in Hippocampal Volume as a Function of BMI and Reward Sensitivity

open access: yesFrontiers in Behavioral Neuroscience, 2020
Sensitivity to reward is a personality trait that predisposes a person to several addictive behaviors, including the presence of different risky behaviors that facilitates uncontrolled eating.

Functional neuroimaging in subjective cognitive decline: current status and a research path forward

open access: yesAlzheimer's Research & Therapy, 2020
Subjective cognitive decline is a putative precursor to dementia marked by perceived worsening of cognitive function without overt performance issues on neuropsychological assessment.
