Normalization accounts for temporal dynamics in human somatosensory cortex

The paper shows that divisive normalization models better capture temporal dynamics in human somatosensory cortex compared to linear models, mirroring visual cortex findings.

Cerebrovascular pulsatility differs across vascular compartments and is altered by hypercapnic stimuli: a BOLD fMRI study

This study introduces a cardiac-specific BOLD fMRI-based pulsatility index, validates its sensitivity to hypercapnia, and shows its correlation with vascular reactivity and venous blood volume.

Neuronal or vascular receptive fields? On the relation between BOLD-fMRI population receptive field (pRF) estimates and cortical vascularization.

This study examines how vascular compartments affect pRF size estimates in early visual cortex using BOLD-fMRI and finds no significant vascular influence on pRF size.

A fully synthetic three-dimensional human cerebrovascular model based on histological characteristics to investigate the hemodynamic fingerprint of the layer BOLD fMRI signal formation

The paper presents a computational framework to simulate BOLD fMRI signal formation in a synthetic human 3D cortical vasculature model, showing that human-specific features significantly affect the BOLD fingerprint.

Moving in on human motor cortex. Characterizing the relationship between body parts with non-rigid population Response Fields.

The paper characterizes body part relationships in motor cortices using a non-rigid population Response Field model and graph theory, revealing somatotopic structures and unique response profiles for specific body parts.

The many layers of BOLD. On the contribution of different vascular compartments to laminar fMRI.

This study quantifies how macro- and micro-vascular compartments affect laminar BOLD fMRI responses under hypercapnic and hyperoxic conditions.

A touch of hierarchy. Population Receptive Fields reveal fingertip integration in Brodmann areas in human primary somatosensory cortex.

The paper uses population receptive field modeling to show a functional hierarchy in human primary somatosensory cortex, with increasing pRF sizes from BA3 to BA2.
