The interpretation of stress is believed to occur in the cerebral cortex of the brain based upon sensory and other input (such as from chemo-receptors). The two categories of stress act through somewhat different neurological mechanisms, but the general features are similar. Cognitive processes are involved in the assessment of the input for both categories as to whether the input represents a potential threat in a routine manner. The amygdala appears to have a central role in the stress response

Neural Interfacing In the motion picture “RoboCop” scientists during a future time implanted a human head into the body of a futuristic robot creating an almost unstoppable police officer. During 1987, when this movie was produced, the idea of man combining with machine was considered pure fantasy. However, advances in technology in the year 2000 and further studies in recent years have proven that this idea may, in time, become a reality. On October 13th 2003, sciencedaily.com in their

Chapter 1 Quantum Neural Network 1.1 Introduction and Background The eld of articial neural networks (ANNs) draws its inspiration from the working of human brain and the way brain processes information. An ANN is a directed graph with highly interconnected nodes called neurons.Each edge of the graph has a weight associated with it to model the synaptic eciency. The training process involves updating the weights of the network in such a way that the network learns to solve the problem

Background: Although decades of neuroscience research has shed light on how the brain represents different types of information, far less is known about the neural basis of conceptual knowledge. Early neuroscientist in the nineteenth century proposed that concepts are anchored to sensory and motor experiences; however, there has been much disagreement ever since [old grant 15, 28]. This idea has gained momentum under the title of ‘embodied’ cognition [OLD grant 1]. In particular, the theory argues

Introduction Artificial neural networks are a class of computational structures (Lesk, 2013) made up of several processing elements, called artificial neurons that are connected and organized in layers (Larder et al., 2007). They are capable of generating models for the detection of non linear functions(..). Their algorithms are extensively applied in biology and medicine to solve complex problems, more specifically for prediction or classification of solutions or to refine methodological aspects

The Effect of Aging on Neural Cells Introduction: Neurogenesis is defined as the creation of new brain cells. Before studies proved that neural cells do have the capacity to proliferate and repair themselves, it was often believed that species are born with a distinct amount of neural cells and as time passes, these cells would die without the ability to be healed or replaced. It was thought that the cells were mainly formed during the embryonic and perinatal stages in the mammals (Ming and Song

Neural crest cells are transient vertebral cell types, which form at the boundary between the neural plate and surface ectoderm. They are multipotent and able to migrate and differentiate into numerous derivatives resulting in them being referred to as the ‘fourth germ layer’. It is thought that the evolution of vertebrates is due to large-scale genome duplications which occurred early in the vertebrate lineage. Research suggests that there were two rounds of genome duplication during early vertebrate

The biological development of the brain enriches the capability of a brains capacity for knowledge. Neural plasticity (brains capacity) changes its structure in response to experience and stimulation. Enriched learning promotes continuous stimulation although lack of stimulation causes pruning. The neurons grow dendrites which branch into neighbouring neurons to allow processing of the hippocampus reconstructing a new memory if stimulation occurs frequently (Duchesne & McMaugh, 2016, p.42) The environment

1. Introduction Convolutional neural systems (CNNs) are suitable for unraveling visual record that depend on hand writing recognition task and characterization [1, 3]. They have an adaptable design which do not need to have complex strategies, for instance, momentum, weight rot, structure dependent learning rates or even finely tuning the engineering[1]. CNNs have additionally accomplished the cutting edge comes about for character acknowledgment on the MNIST informational collection of manually

Sensori-neural Deafness Sensori-neural deafness is medically irreversible. It is caused by a malfunction of the inner ear. So when sounds reach the inner ear, they go no further. In normal cases the sound will be transmitted to the brain. The cause of hearing impairment has various forms. Such as, a fault in the genetic blueprint, if one chromosome from either parent is damaged. This is the main
