We report on the synthesis and electrochemical properties of multi-walled carbon nanotubes (MWCNTs) for supercapacitor devices. Freestanding vertically-aligned MWCNTs and MWCNT powder were grown concomitantly in a one-step chemical vapour deposition process. Samples were characterized by scanning and transmission electron microscopies and Fourier t...

The primary somatosensory cortex (S1) of mammals is critically important in the perception of touch and related sensorimotor behaviors. In 2015, the Blue Brain Project (BBP) developed a groundbreaking rat S1 microcircuit simulation with over 31,000 neurons with 207 morphoelectrical neuron types, and 37 million synapses, incorporating anatomical and...

Understanding cortical function requires studying multiple scales: molecular, cellular, circuit, and behavioral. We develop a multiscale, biophysically detailed model of mouse primary motor cortex (M1) with over 10,000 neurons and 30 million synapses. Neuron types, densities, spatial distributions, morphologies, biophysics, connectivity, and dendri...

We developed a detailed model of macaque auditory thalamocortical circuits, including primary auditory cor-tex (A1), medial geniculate body (MGB), and thalamic reticular nucleus, utilizing the NEURON simulator and NetPyNE tool. The A1 model simulates a cortical column with over 12,000 neurons and 25 million synapses,incorporating data on cell-type-...

Predictive processing theories conceptualize neocortical feedback as conveying expectations and contextual attention signals derived from internal cortical models, playing an essential role in the perception and interpretation of sensory information. However, few predictive processing frameworks outline concrete mechanistic roles for the corticotha...

We are delighted to present you the Proceedings of the 2022 CNS meeting. The CNS meeting encourages approaches that combine theoretical, computational, and experimental work in the neurosciences, and provides an opportunity for participants to share their views. The abstracts corresponding to speakers' talks and posters are what you find collected...

Purpose One of the main causes of long-term prosthetic abandonment is the lack of ownership over the prosthesis, which was caused mainly by the absence of sensory information regarding the lost limb. The period where the patient learns how to interact with a prosthetic device is critical in rehabilitation. This ideally happens within the first mont...

Therapeutic strategies capable of inducing and enhancing prosthesis embodiment are a key point for better adaptation to and acceptance of prosthetic limbs. In this study, we developed a training protocol using an EMG-based human-machine interface (HMI) that was applied in the preprosthetic rehabilitation phase of people with amputation. This is a c...

For a better rescuing of people with disabilities, it is crucial the development of new assistive technologies and therapeutic methods to rehabilitate people with some disabilities to integrate them to a complete social life. A very promising tool is the physiological self-regulation protocols based on biofeedback training. Biofeedback protocols ar...

Foreword from the editors. We hosted four keynote speakers: Wolf Singer, Bill Bialek, Danielle Bassett, and Sonja Gruen. They enlightened us about computations in the cerebral cortex, the reduction of high-dimensional data, the emerging field of computational psychiatry, and the significance of spike patterns in motor cortex. From the submissions,...

Background: The embodiment of a prosthesis can bring a series of benefits during the rehabilitation of people with amputation, such as improvement of motor control and sense of agency, in addition to optimizing the training process with the prosthetic limb. New therapeutic strategies capable of enhancing prosthesis embodiment are, therefore, a key...

Introduction The Oxfordshire Community Stroke Project (OCSP) proposed a clinical classification for Stroke patients. This classification has proved helpful to predict the risk of neurological complications. However, the OCSP was initially based on findings on the neurological assesment, which can pose difficulties for classifying patients. We aimed...

One of the main causes of long-term prosthetic abandonment is the lack of ownership over the prosthesis, caused mainly by the absence of sensory information regarding the lost limb. One strategy to overcome this problem is to provide alternative feedback mechanisms to convey information respective to the absent limb. To address this issue, we devel...

[https://repositorio.unifesp.br/handle/11600/59909] (EN) We report the development of an Integrated Biofeedback system for the rehabilitation of Transfemural Amputees during the phase of Preprosthetic training. Our main objective developing this systema is to apply it as a rehabilitation tool, providing amputee people with an alternative to bypass...

Resumo The objective of this study is to evaluate the differences in deformation presented by a latex material and a Rat Right-Ventricle tissue under biaxial loading. In order to perform the testing, it was used a planar biaxial loading technique, and the collected data was used to measure the stretching response of each material. The samples were...

O objetivo deste trabalho é desenvolver uma ferramenta para auxiliar no processo de recuperação pós-operatória de procedimentos de mastectomia. Utilizando de ferramentas de reconhecimento corporal e interfaces virtuais, serão quantificados os dados relacionados à amplitude de movimento de ambos os braços dos pacientes, agindo como uma ferramenta de...
