Artificial electrical stimulation of the nervous system is one of the foundations of neurotechnology. However‚ the use of electrical currents to stimulate the nervous system presents several challenges. It is difficult to achieve selective stimulation of only the targeted neurons without activating neighboring neurons. Further‚ electrochemical reactions at the electrode-tissue interface may lead to electrode dissolution or tissue damage. As an alternative‚ magnetic stimulation can be used to stimulate

Effective Communication and Professional Relationships with Children‚ Young People and Adults Sarah Haycock-Lewandowski 17/03/2012 A key element of the role of any member of support staff in a school or other education environment‚ is communication‚ both with children and adults. Whilst it is important for children to learn cognitive skills‚ it is equally important that they also learn skills that will allow them to function effectively in society. A significant proportion of the latter can

Affect of Culture on Human Behavior and Interaction Viktorea Ford Scott Community College Culture is‚ by definition‚ the behaviors and beliefs characteristic of a particular social‚ ethnic‚ or age group ("Dictionary.com‚" 2012). It helps give people a sense of balance and sanity within their lifestyle. They follow “rules” and customs on a daily basis based on the things they have been surrounded by or introduced to. Therefore‚ the effects on human behavior may vary. Considering the many different

Some theorists believe that human behaviour is ‘wired in’‚ that is innate. What are some of the arguments that support and contest this view? In opposition to the view of human behaviour as being “innate” are the theories of behavioural development through socialisation. These theories stress the acquisition of language and social interaction throughout childhood as key determinates of an individual’s behaviour (Germov and Poole 2007). George Herbert Mead and John Piaget both developed theories

Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain why increasing

The relationship between sexual selection and human reproductive behaviour Sexual selection is a special type of natural selection that is concerned with an organisms ability to successfully reproduce. Survival is no guarantee of passing gene variants to the next generation‚ that can only happen if the animal reproduces. Males usually compete to mate with females According to Trivers (1972)‚ "Where one sex invests considerably more than the other‚ members of the latter will compete among
