Neural coding of tactile decisions in the human prefrontal cortex [PDF]

, 2006
The neural processes underlying tactile decisions in the human brain remain elusive. We addressed this question in a functional magnetic resonance imaging study using a somatosensory discrimination task, requiring participants to compare the frequency of

Functional Connectivity Evoked by Orofacial Tactile Perception of Velocity

Frontiers in Neuroscience, 2020
The cortical representations of orofacial pneumotactile stimulation involve complex neuronal networks, which are still unknown. This study aims to identify the characteristics of functional connectivity (FC) evoked by three different saltatory velocities

Fingolimod increases parvalbumin-positive neurons in adult mice

IBRO Neuroscience Reports, 2022
In recent years, it has been shown that central nervous system agents, such as antidepressants and antiepileptic drugs, reopen a critical period in mature animals.

Deficits in Behavioral Functions of Intact Barrel Cortex Following Lesions of Homotopic Contralateral Cortex

Frontiers in Systems Neuroscience, 2018
Focal unilateral injuries to the somatosensory whisker barrel cortex have been shown cause long-lasting deficits in the activity and experience-dependent plasticity of neurons in the intact contralateral barrel cortex.

Somatosensory cortex participates in the consolidation of human motor memory.

PLoS Biology, 2019
Newly learned motor skills are initially labile and then consolidated to permit retention. The circuits that enable the consolidation of motor memories remain uncertain.

Cortical and subcortical somatosensory regulation of dopaminergic neurons: role of the superior colliculus [PDF]

, 2011
Dopaminergic (DA) neurons exhibit a short-latency, phasic response to unexpected biologically salient stimuli, including rewards. Despite extensive research on this DA signal, very little is known about the sources of sensory ...

More than skin deep: body representation beyond primary somatosensory cortex [PDF]

, 2010
The neural circuits underlying initial sensory processing of somatic information are relatively well understood. In contrast, the processes that go beyond primary somatosensation to create more abstract representations related to the body are less clear.

c-Fos expression during temporal order judgment in mice. [PDF]

PLoS ONE, 2010
The neuronal mechanisms for ordering sensory signals in time still need to be clarified despite a long history of research. To address this issue, we recently developed a behavioral task of temporal order judgment in mice.

Stimulus awareness is associated with secondary somatosensory cortex activation in an inattentional numbness paradigm

Scientific Reports, 2023
While inattentional blindness and deafness studies have revealed neural correlates of consciousness (NCC) without the confound of task relevance in the visual and auditory modality, comparable studies for the somatosensory modality are lacking.

Rich spatio-temporal stimulus dynamics unveil sensory specialization in cortical area S2

Nature Communications, 2018
Sensory tuning properties of neurons in the secondary whisker somatosensory cortex (wS2) are not well understood. Here, the authors report that wS2 neurons supralinearly integrate concurrent multi-whisker input with larger temporal windows than primary ...
