Nerves are bundles of thin fibers (made up primarily of axons) that perform the vital function of carrying information from one part of the body to another. They carry information from sensory organs to the central nervous system (brain & spinal cord) and back. Nerves are further classified b...
The number of image features extracted and the quality of the training data fed to the algorithm are critical elements of hypothesis formation. After feature extraction, the system generates a probability score and assigns it to objects present in the image. This is mainly done to lessen the wor...
What is the site where the medial fibers of the optic nerves cross? What are autonomic nerves? How does nervous tissue interact with muscle tissue? Communication between axons and muscle fibers occurs at specialised synapses called ___. What tissue...
The deep parts in the folds are called the sulci, and the raised portions are called the gyri. The uneven surface of the cerebral cortex holds neurons vital for your brain functions. Your inability to carry out higher mental functions without this organ underlines the importance of the cerebral...
An axon, or nerve fiber, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron's cell body or soma. Axons arein effect the primary transmission lines of the nervous system, and as bundles they help make up nerves. ...
The spinal cord lies below the brain and is continuous with the brainstem. It contains neuronal cell bodies and bundles of axons that connect the brain and different parts of the body. Besides being a critical conduit of information, the spinal cord can carry out some functions without input ...
midbrain down to the medulla, is involved in various functions, including sleep and arousal, temperature regulation, and motor control. Groups of motoneurons form two cranial nuclei; their axons branch out to create the oculomotor nerve and the trochlear nerve, both of which control eye movement...
Take soccer players, who are known for repeatedly heading soccer balls. Using a technique called Diffusion Tensor Imaging, we’re beginning to find out what effect that has on the brain. This method allows scientists to find large axon bundles and see how milder blows might alter them ...
running in bundles, deeper in the brain. Until very recently, not much was known about the interface between the white and gray matter—the so-called superficial white matter—because methods were lacking to study it in living human brains. Yet, previous investigations had suggested the region ...
