In this contribution we present multi-channel microinjector arrays fabricated by a reliable three-layer SU-8 process and assembled with glutamate biosensor microprobes'. It enables local delivery of specific liquids into brain tissue for the stimulation or ...

Recent philosophical and neuroscientific theories converge on the assumption that the basic foundations of self-consciousness lie in those brain systems that represent the body. Neurological cases in which this basic bodily self-consciousness is disturbed ...
Repetition of environmental sounds, like their visual counterparts, can facilitate behavior and modulate neural responses, exemplifying plasticity in how auditory objects are represented or accessed. It remains controversial whether such repetition priming ...
Human bodies provide a particularly rich source of visual information. Whereas most previous studies have focused on the neural mechanisms during the perception and recognition of human bodies, the aim of the present study was to investigate the time cours ...
The general structure of the mammalian neocortex is remarkably similar across different cortical areas. Despite certain cytoarchitectural specializations and deviations from the general blueprint, the principal organization of the neocortex is relatively u ...
Four experiments examined the disruptive effects of selective lesions in limbic thalamic nuclei on retrosplenial cortex function, as characterized by striking changes in immediate-early gene activity. Major goals were to test the specificity of these retro ...
This work examines the influence of changes in baseline activity on the intrinsic functional connectivity fMRI (fc-fMRI) in humans. Baseline brain activity was altered by inducing anesthesia (sevoflurane end-tidal concentration 1%) in human volunteers and ...
Blood oxygenation level dependent (BOLD) signal changes occurring during execution of a simple motor task were measured at field strengths of 1.5, 3 and 7 T using multi-slice, single-shot, gradient echo EPI at a resolution of 1x1x3 mm(3), to quantify the b ...
Context Two sets of findings predict smaller cerebral cortical gray matter volume in adult posttraumatic stress disorder (PTSD). Measures of intracranial tissue volume and cerebral tissue volume have been observed to be smaller in adolescents with maltreat ...
In the cerebral cortex, the activity levels of neuronal populations are continuously fluctuating. When neuronal activity, as measured using functional MRI (fMRI), is temporally coherent across 2 populations, those populations are said to be functionally co ...
