Activation of the <u>Serotonin </u>neurons of the forebrain would be expected to <u>suppress </u>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.

<u>Answer:</u>
<em>150°E longitude passes through the continents of Asia as well as Australia.
</em>
<u>Explanation:</u>
The longitude passes through two oceans, the Arctic Ocean and Pacific Ocean. It passes through countries Russia, Papua New Guinea and Australia. Australia and Papua New Guinea are countries in the Australian continent while Russia is part of Asia.
Longitude is towards east or west of Greenwich meridian. The angle made by the line drawn from the centre of earth to a point with the equatorial plane of earth is the latitude of that point. The latitude of the equator of earth is 0° and the latitude of poles is 90°.
Answer: c) Absolute refractory theory
Explanation:
Absolute refractory theory defines about time of action potential where any other action potential cannot get initiated through stimulus towards neuron irrespective of strength and size .
According to the question, absolute refractory period is being described through wait that occurs between switching of channel.This wait cannot be overcomed even though channel is switched forcefully or rapidly for change because it is acting as action potential.
Other options are incorrect because potential gradation, relative refactor period and regenerative timeout does display action potential during certain time period where other stimulus cannot invoke another action potential irrespective of its strength.
Thus, the correct option is option(c).

The scoring system would determine which course of actions that would bring the most benefit to us (score the highest) based on pre-determined criteria.
We could rely on this system rather than based on our own analytic that most likely affected by our personal bias and emotion.</span>
