Obtaining optimal data length for FMRI images
Interest in brain hemodynamics has led to a substantial increase in state of the art research within the field of functional Magnetic Resonance Imaging (fMRI). FMRI enables research to be conducted on brain mapping in healthy individuals, as well as in patient populations. The need for accurate …

Brain Tumor Detection and Classification from MRI Images
<p>A brain tumor is detected and classified by biopsy that is conducted after the brain surgery. Advancement in technology and machine learning techniques could help radiologists in the diagnosis of tumors without any invasive measures. We utilized a deep learning-based approach to detect and …

Novel Electrochemical Methods for Human Neurochemistry
… for use in human patients already receiving brain surgery. The process of modifying established FSCV methods for clinical application has led improved model building strategies, and a new "random burst" sensing protocol. The advent of random burst sensing raises questions about the …

Active tremor control of human motion disorder
… can not eat. Similarly, surgeons performing eye surgery must have very little tremor to enable them to operate on the small anatomy of the eyes. In both cases, a motion disorder known as essential tremor can be the cause of the insufficient level of human motor performance. Current treatments for …

Investigation of the Clinical Utility of the Spatio-Spectral Dynamics of Sensorimotor ECoG in Response to Different Somatosensory Stimulation Modalities in Human Subjects
Neurosurgeons during eloquent brain surgery conduct vital functional mapping to ensure proper brain function. Usually, following the electrical stimulation of the peripheral nerves, visual assessment of the phase reversal of the somatosensory evoked potentials (SSEPs) is employed to delineate the …

DESIGN AND CONTROL OF A ROBOTIC SYSTEM TO ASSIST WITH MRI-GUIDED INTERVENTIONS
… needle placement and kidney transplant to brain surgery and artery bypass. As new technologies are introduced and the development of more sophisticated and integrated robotic systems is made possible, more challenging operations are targeted to be enhanced using automated mechanisms. …

Deep Learning-Based Brain Tumour Detection and Classification
Early and accurate detection of brain tumours is essential for improving patient outcomes and guiding effective treatment plans. Traditional diagnostic procedures such as biopsies, performed after brain surgery, are invasive and carry significant risk. With recent advancements in technology, deep …

The Use of High-Density ECoG for Functional Mapping and Neural Decoding
… mapping of eloquent cortex during the resective brain surgeries, especially brain tumor surgeries, is a critical procedure for optimizing survival and quality of life. Electrocorticography (ECoG) can map functional areas without delivering electrical current to the cortex by placing electrodes …

The innate ability of pet dogs to spontaneously anticipate epileptic seizures
… the only intervention available is targeted brain surgery to excise the seizure source, but waiting lists are long and the procedure expensive. Anecdotally, dogs appear to be capable of anticipating seizures although no empirical evidence has been offered to support this claim. Many accounts …

Characterizing Changes in the Brain During Hydrocephalic Development and Exploring Potential Treatment Strategies
… fluid builds up within the ventricles of the brain. Thus, the only available treatments are surgical, invasive, and prone to complications. There is a global need for successful treatment strategies without brain surgery. Choroid plexus epithelial cells (CPEC) are responsible for production of …

Role of Slit2 in Reducing Complications after Surgical Brain Injury
<p>Surgical brain injury (SBI) is the inadvertent injury to brain tissue at the perisurgical site which occurs due to neurosurgical maneuvers such as incision, retraction, and electrocoagulation that can result in post-operative complications. Blood brain barrier (BBB) disruption and …
