Abstract PC12 cells are a common model system used to study neuronal differentiation. Here we provided evidence supporting PC12 neuronal differentiation in response to NGF. Light microscopy showed that PC12 cells acquire neuronal features following two days of treatment, such as outgrowths similar in morphology to neurites and connections that could be synapses. Immunocytochemistry for …

A group of researchers discovered a way to detect fasciculation in muscles, which serves to detect early signs of motor neuron disease (MND). The article, Ultrasound-Based Detection of Fasciculations in Healthy and Diseased Muscles, were published by IEEE Xplore. This article was peer reviewed and can be found in Transactions on Biomedical Engineering or online, …

The article stated that when it comes to long-term memory formation, it is accepted that it is formed by the strength of the synapse (space between two neurons). Neurons are the cells in our brain which retrieve and send information throughout our body. There is a theory that long-term memory is actually encoded by modifications …

“ Motor control requires the integration of sensory information which are relayed as action potential’s down the neural pathways by receptors such as mechanoreceptors, photoreceptors, thermoreceptors. The sensory systems are used for vision, touch, hearing, proprioception, smell and taste, while receptors are used to detect the stimulus internally and externally. Each types of receptors are …

Active contours or snakes are computer-generated curves that move within images to find object boundaries. They are often used in computer vision and image analysis to detect and locate objects, and to describe their shape. For example, a snake might be used edge detection, corner detection, motion tracking, and stereo matching; one might be used …

Artificial neural networks (ANNs) or connectionist systems are computing systems inspired by the biological neural networks that constitute animal brains. Such systems learn (progressively improve performance on) tasks by considering examples, generally without task-specific programming. For example, in image recognition, they might learn to identify images that contain cats by analyzing example images that have …

During a neuron activation, it is better to understand what is the actual neuron output. There are quite a few transfer functions that can be utilized. The traditional one is called “sigmoid activation function”, but the tanh (hyperbolic tangent) function can also be used to transfer outputs. At this moment, the rectifier transfer function become …

“ We can think of our brain as a complicated electric circuit consisting of billions of neurons and trillions of synapse (gap between one neuron and the other). Each and every neuron can be considered as a component of this complex circuit. An interesting fact is, every aspect of human behavior, from reflexes to reasoning …

What is neural network? A neural network is a system of hardware and/or software patterned same as the operation of neurons in the human brain. Neural networks are also called artificial neural networks. It is a type of deep learning technologies. A neural network usually includes a large number of processors operating in parallel and …

Neurotransmission (Latin: transmissio “passage, crossing” from transmittere “send, let through”), also called synaptic transmission, is the process by which signaling molecules called neurotransmitters are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and activate the receptors on the dendrites of another neuron (the postsynaptic neuron). A similar process occurs …

Abstract In the field of biomedical engineering Multichannel neural recording is one of the most important topics. Without degrading the quality the large amount of data is to be easily transfer through wireless transmission. For neural data reduction there are so many techniques that follow different factors. In the field of signal processing Video compression …

The idea of a “hormone” was not well-received by the scientific community, and it was a difficult concept to portray, as scientists had not been familiar with the idea of chemical messengers influencing the actions of cells in the body. Many scientists, such as Arnold Adolph Berthold, Thomas Addison, Joseph von Mering and Oskar Minkowski, …

Mirror neurons are neurons located in the brain. They allow one to mirror another’s behaviour as though the observer washimself (or herself). Mirror neurons are not form-sensitive and have been directly observed in primate species.They fire when an animal acts or when the animal observes the same action performed by another and only in responseto …

Researchers are discovering new evidences about how human brain works and functions while practicing the materialization of thoughts. Manifestation and visualization are the synonyms for this process as well. A recent study claimed that it is possible to materialize thoughts with the help of regular practice. You can achieve whatever you want in life by …
