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.

Answer: a string of military losses sustained against outside forces. Rome had tangled with Germanic tribes for centuries, but by the 300s “barbarian” groups like the Goths had encroached beyond the Empire's borders. a Germanic barbarian by the name of Odoacer took control of Rome. He became king of Italy and forced the last emperor of Rome, Romulus Augustulus, to give up his crown. Many historians consider this to be the end of the Roman Empire. With the fall of Rome, many changes occurred throughout Europe. The collapse of the Roman Empire in the fifth century. Two of the main events of the Fall of Rome were the plundering of the city of Rome by an invading tribe, the Vandals, in the middle years of the century and the abdication of the last Roman emperor, Romulus Augustulus, in 476.
