The biology of a brain in crisis
The brain in crisis
The limbic system has a significant part to play when it comes to the stress as well as emotional responses. The parts of the limbic system that most interest me in the exploratory research to a person in crisis, as it relates to Maslow’s needs of survival and security and its effects on motivational and emotional behaviors are the amygdala, hippocampus, hypothalamus and the thalamus (Kalat, 2009).
In addition to the limbic system, the interest also extends to the autonomic nervous systems effects, in the context of motivation and behavior as well as the sympathetic nervous system with the parasympathetic nervous system. The interests in these specific areas are important because they are the primary parts of the brain that affect stress and anxiety when it comes to motivational behavior and emotions (Kalat, 2009).
also, analysis of the leading hormones that affect emotion, behaviors, and motivation are the primary interest of the exploratory research. Hormones such as cortisol, adrenaline, norepinephrine aka noradrenaline and epinephrine are explored within this context and importance. For the positive hormones, I will examine endorphins, dopamine, serotonin, GABA gamma-aminobutyric as it relates to aiding or hurting an individual’s survival and security behaviors.
Amygdala in stress. The amygdala, located at the inner tip area of the temporal lobe, gets its information input from the eyes and ears as well as other sensors and takes in potential threat stimulus from the outside world. The sensor then sends the information to the amygdala for emotional processing. The amygdala interprets the situation and stimulus by observing that there is danger present, it sends the alarm to the hypothalamus (Plotnik & Kouyoumjian, 2011).
In addition, the stimulation of the amygdala is not only activated by actual threats but also by memories of past dangerous and emotional events (Plotnik & Kouyoumjian, 2011). The activation of the amygdala will even have an impact on motivation, behavior, and emotions that lead to survival and security.
Within the amygdala, there are specialized neurons called the fear neurons that respond to an emotional situation that presents fear. Also, the amygdala is the place where the processing of emotions such as fear connected to memories thereby becoming stimulated when the memory of a fearful event is recalled (Plotnik & Kouyoumjian, 2011)
