Imaging Somatosensory Cortex: Human Functional Magnetic Resonance Imaging (fMRI)
, 2022 Functional magnetic resonance imaging (fMRI) is a powerful tool for imaging somatosensory cortex, providing a means to non-invasively measure cortical activity in awake and behaving humans. Notably, this technique has permitted the homunculus – a hallmark of primary somatosensory cortex (S1) organization – to be examined with unprecedented detail. With

The Mind From Within: Visceral Roots of Human Cognition
Advanced Science, EarlyView.The physiological activity of visceral organs, such as the heart, the lungs, and the gut, is surprisingly linked to many sophisticated mental operations, such as remembering the past, being aware of ourselves, making choices, and forging social bonds.

Preserving Motor Features by Alternative Re‐Referencing to Remove Heart Artifact on the Stentrode
Advanced Science, EarlyView.Endovascular brain‐computer interfaces record neural activity from within cerebrovasculature, at the expense of electrocardiogram contamination. Band‐limited independent component analysis separates this heart‐based artifact from task‐relevant neural activity in each frequency band, enabling the reconstruction of cleaner neural recordings without the ...

Current methods and limitations for longitudinal fMRI analysis across development
Developmental Cognitive Neuroscience, 2018 The human brain is remarkably plastic. The brain changes dramatically across development, with ongoing functional development continuing well into the third decade of life and substantial changes occurring again in older age.

The variation of functional connectivity and activity before and after thalamotomy surgery (review)
Frontiers in Human Neuroscience, 2023 Ablation surgeries are utilized to treat certain brain disorders. Recently, these surgeries have become more prevalent using techniques such as magnetic resonance guided focused ultrasound (MRgFUS) ablation and Gamma knife thalamotomy (GKT).

Advanced Science, EarlyView.Bilateral temporal accelerated 40‐Hz tACS improves cognitive function in patients with Alzheimer's disease. Resting‐state fNIRS identifies treatment‐related increases in frontotemporoparietal functional connectivity, which are associated with cognitive improvement. ABSTRACT The temporal lobes are key hubs for memory and cognition.
