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.

Brenda's therapist wants her to talk about her childhood. Her therapist's name is <u>Sigmund Freud.</u>
Sigmund Freud was a psychoanalyst who developed psychoanalytic psychotherapy. This theory relies on the premise that some maladaptive functioning is present in the patients, and that this is often unconscious.
This maladaptation occurs from early childhood, often due to emotional hardships, and gradually coagulates to cause problems later in life.
Psychoanalytic psychotherapy focuses on uncovering and resolving these inner and unconscious conflicts, in order to alleviate the outward symptoms.
Psychoanalytic psychotherapy emphasizes the forming of strong interpersonal bonds between the patient and the therapist, based on trust and confidence.

Researchers must utilize a control group in a scientific study because <span>it is important to show that between two groups that were similar from the beginning of the study, the one that received the manipulation is the one that changes. Note that the control group is the group in the experiment that does not receive manipulation by the experimenter and is thus used as basis for how the other test subjects changed. </span>
