Neural and Hormonal Mechanisms in Aggression Aggression in humans has been associated with low levels of serotonin and high levels of dopamine. Usually‚ serotonin has a calming effect‚ which inhibits aggression. When serotonin levels are low‚ this inhibitory effect is removed and people are less able to control their aggressive behaviour. Evidence for the importance of serotonin comes from two main sources. Brown (1982) found that there were low levels of the waste products of serotonin in the

Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying

Mechanism Description of an electric guitar Introduction An electric guitar is a stringed musical instrument played with fingers or a plectrum (pick). It consists of a body‚ a neck and a headstock to which usually six steel strings are attached. The magnetic pickups transform the vibrations of the steel strings into audio signals that are driven through an amplifier. Thus‚ the amplifier is also an essential part of the electric guitar. It was the need of amplified sound

Clearly many photographic negatives require a standardized process to portray the artists given intention‚ either due to the photographer’s methodology or the subject matter in hand. In the way that the photographic image is portrayed in contemporary society; in such industries as advertisement‚ fashion‚ product‚ landscape and even art photography‚ higher than life quality is the current fashion. Artists working in alternative methods seem to be viewed with an alternative eye‚ their work can’t be

When you encourage others to do well‚ work runs smoothly too. Employees are more likely to enjoy their job and be willing to give their best when they know well what is expected from work and receive feedback. Businesses also have to look into motivating employees through

Feedback ORM Exam January 2015 Overall‚ students’ performance on the Term 1 ORM exam was quite good. The average mark was 56.11. While no marks above 80 were recorded‚ a sizeable number of students achieved a mark of 70 or above. Students that received a mark below 40 tended to have not meaningfully attempted one or more questions. Indeed‚ a number of students did not to adequately manage their time in the exam and failed to provide full answers to each question. Feedback from some students after

Lab 1: Cell Transport Mechanisms and Permeability Purpose The purpose of this experiment is to have a better understanding of the subject matter and to understand the difference between active and passive cellular transport. It will also help to define diffusion and describe the process that occurs when certain solutes come in contact and are either stopped or move through the plasma membrane. Hypothesis I believe the plasma membrane is selective about what is able to and not able to pass

short writing assignment Shannon Prendergast Nagel explains negative good. as the absence of something bad and he describes a negative evil as the absence of something good. He is comparing these as they apply to death in this chapter. Assuming that death without anything is either good or bad to the person who dies. . He describes death as being either a negative evil or negative good. It can be described as a negative good because it can lack something bad. If someone is dying from a painful
