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

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

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

The spinal canal is the hollow vertical hole formed by the bones of the spinal column. Anything that causes this bony hole to shrink can squeeze the nerves inside. This narrowing can irritate the nerve roots that branch out from the spinal cord‚ or it can squeeze and irritate the spinal cord itself. This may cause pain‚ numbness‚ or weakness‚ most

INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein‚ glutathione; and changes in the expression of apoptosis associated
