Relation between palm and finger cortical representations in primary somatosensory cortex: A 7T fMRI study
Sign Up to like & getrecommendations! Published in 2021 at "Human Brain Mapping"
DOI: 10.1002/hbm.25365
Abstract: Many studies focused on the cortical representations of fingers, while the palm is relatively neglected despite its importance for hand function. Here, we investigated palm representation (PR) and its relationship with finger representations (FRs) in… read more here.

Secondary somatosensory cortex of primates: beyond body maps, toward conscious self-in-the-world maps
Sign Up to like & getrecommendations! Published in 2020 at "Experimental Brain Research"
DOI: 10.1007/s00221-020-05727-9
Abstract: Recent human imaging studies have revealed the involvement of the secondary somatosensory cortex (SII) in processes that require high-level information integration, such as self-consciousness, social relations, whole body representation, and metaphorical extrapolations. These functions are… read more here.

DOI: 10.1007/s10548-022-00888-y
Abstract: Recent studies have established the presence of nociceptive steady-state evoked potentials (SSEPs), generated in response to thermal or intra-epidermal electric stimuli. This study explores cortical sources and generation mechanisms of nociceptive SSEPs in response to… read more here.

DOI: 10.1016/j.neulet.2019.134374
Abstract: Sensory cortex topographic maps consist of organized arrays of thalamocortical afferents (TCAs) that project into distinct areas of the cortex. Formation of topographic maps in sensory cortices is a prerequisite for functional maturation of the… read more here.

DOI: 10.1016/j.neuroimage.2017.08.014
Abstract: Abstract Attention to sensory information has been shown to modulate the neuronal processing of that information. For example, visuospatial attention acts by modulating responses at retinotopically appropriate regions of visual cortex (Puckett and DeYoe, 2015;… read more here.

DOI: 10.1016/j.neuron.2017.05.018
Abstract: I outline a microcircuit theory of somatosensory cortex as a body model serving both for body representation and "body simulation." A modular model of innervated and non-innervated body parts resides in somatosensory cortical layer 4.… read more here.
