The effectiveness of Farabloc technology with Mirror Therapy in reducing phantom limb pain in individuals with a unilateral lower extremity vascular amputation
… fields and Mirror Therapy to assist in the sensory cortex reorganization, to decrease or eliminate phantom limb pain in vascular amputees. Methods:fourteen older adults with a unilateral vascular amputation participated in the study. Nine individuals started the intervention within 48 hours …

Shedding light on memory retrieval: reactivation of related information and its association with the hippocampus
… experiments examined this reactivation of sensory cortices by looking at its association with the hippocampus, both in terms of relating the reactivation activity to structural measures of the hippocampus but also to possible methods by which the hippocampus and sensory cortex communicate. …

A tailored biocompatible neural interface for long term monitoring in neural networks
… activity were obtained in both cerebellum and cortex cerebri (papers I-III). In paper IV, we evaluated the importance of mechanical flexibility and demonstrated that probe flexibility has a significant impact on the astroglial scar, but not on the loss of neurons nearby. Moreover, by embedding …

Dendritic Spine Density Varies Between Unisensory and Multisensory Cortical Regions
… mental retardation, enhanced during development, sensory enrichment or physical exercise, or fluctuate during the reproductive cycle. Thus, for a given neuron type, it might be expected that dendritic spine number might achieve a dynamic optimum. Indeed, many studies of spine density of pyramidal …

Behavioral and Functional Brain Correlates of Developmental Coordination Disorder: A Case-Control Study
… robust activations (p < 0.01) in the left motor cortex and left inferior parietal lobe while performing the tracking task. These results imply that the DCD subject relied heavily on visual (instead of tactile) feedback when performing the visuo-motor task as opposed to the control subject who …

Epigenetic Changes in Alzheimer’s and Huntington’sS Disease : A semi-quantitative analysis of histone changes
… gyrus and hippocampus of AD and the motor cortex, sensory cortex and cingulate gyrus of HD post mortem brains compared to age and sex matched neurologically normal control brains. Results obtained from semi-quantitative image analysis and Western blot analyses collectively demonstrated that …

MRI at 3 T of brain functions and fibre tracts adjacent to intracranial tumors
… fingersomatotopy in area 3 b of the primary sensory area (Paper 1); to investigate the potential of fMRI at 3T as a clinical tool for preoperative evaluation of patients with intracranial tumors (Paper 2); to investigate the effect of glioma resection on the spatial extent of fMRI activation …

Brain Dynamics When Alertness Fluctuates but Attentional Demands Persist
… increased synchronisation between the auditory cortex and the rest of the brain. These findings suggested that sustained auditory attention during sleep onset recruited auxiliary brain resources. Next, we sought to confirm that these alertness-related changes in brain dynamics directly …

The Impact of Synchrony On Neuronal Coding and Behavior
… functional and computational module of the neocortex. Although much is known about its laminar structure and synaptic connectivity, how patterns of spiking activity propagate within columnar circuits when the state of the brain changes remains poorly understood. We used multi-electrode laminar …

Subcortical Inputs Governing Cortical Network Activity
Sensory information is represented in cortex by cascades of excitation, the patterns of which are constrained and biased by anatomical connections between neurons. Additionally, in the living animal, functional connectivity is dynamically adjusted by internally generated background activity, which …

Oxygen Polarography in the Awake Macaque: Bridging BOLD fMRI and Electrophysiology
… system and representative of stimulus driven sensory cortex, we show increased tissue oxygen and local field potential power in response to visual stimulus. In area 23 of the posterior cingulate cortex (PCC), a hub of the default-mode network we show decreased oxygen and local field potential …

The Long-Term Teratogenic Effect of Prenatal Alcohol Exposure on the Somatosensory and Motor Cortex of Rats
… alcohol exposure (PAE) on the primary somatosensory (SI) and primary motor cortex (MI). For over 30 years, PAE has been shown to produce a triad of symptoms (growth deficits, craniofacial dysmorphologies and central nervous system disruptions) diagnosed as fetal alcohol syndrome (FAS) in …
