Hundreds of cities in throughout China are the fountainhead of the Yangtze River's pollution, and across the last 50 years, it has been an increase of 73% in pollution volume in the nucleus of the river, through sewage and industrial waste dumping.

Ironically enough, since the Yangtze river was often referred to as “the source of life” in China; due being home to 350 fish species, and accounting for a significant sum of China’s water resources for rice and fishery production as well as a big part of the nation’s GDP, while being a center of great biological wealth.

Activation of the ________ neurons of the forebrain would be expected to ________ aggressive attack.

SCORPION-xisa [38]

Activation of the Serotonin neurons of the forebrain would be expected to suppress aggressive attack.

Numerous studies link elevated impulsive and aggressive behaviors with reduced serotonin metabolites. The opposing association has been substantiated by therapies targeted at directly reducing serotonin cell activity, despite the fact that pharmaceutical reduction of serotonin is linked to an increase in aggression.

Furthermore, it is unclear whether any of the relationships observed may be caused by changed serotonin activity during development. Here, we used two Pharmacogenetic techniques to selectively and reversibly decrease the firing of serotonin neurons in behaving animals in transgenic mice.

A persistent reduction in serotonin neuron firing was linked to increased aggression, as demonstrated by conditional over expression of the serotonin 1A receptor (Htr1a) in serotonin neurons.

By measuring the Galvanic skin response, Dr. Laub is trying to avoid the problem of:

Demand characteristics

<h3>What are demand characteristics?</h3>

Demand characteristics are a form of behavior that participants in a research work exhibit. If they are able to fathom the cues in the research, they often tend to change the way that they behave.

If they change the way they behave, accurate results will not be obtained. So, this issue must be avoided at all costs and that is why Dr. Laub measures the Galvanic skin response.
