Chemistry of Emotions
by Ashli Mohney
EMOTION:
a strong feeling distinguished from reasoning or knowledge.
Example: Joy, Anger, Love and Fear
Information About Human Emotions
+ Emotions are caused by chemical reactions in the brain
+ Different
nuerotransmitters
cause different emotional reactions
+ Chemicals pass from neurons to neurons through
chemical synapses
+Most of the reactions occur in the Limbic System of the brain.
Neurotransmitters
Serotonin
Dopamine
Serotinin contributes to many functions of the body such as regulating
sleep
,
body temperature
,
mood
,
appetite
, and
pain
.
It is linked to many emotions such as
depression
and
anxiety
.
Dopamine controls the reward and
happiness
centers by triggering a blast of
pleasure
. It helps to regulate emotional responses.
It is often called the "
molecule behind our sins
".
Norepinephrine
Similar to Dopamine, it helps you
control stress

and

anxiety
. It also helps with
learning
and
memorization
.
It helps control your emotions by escalating blood sugar levels by opening up the lungs airways and converting fats to fatty acids which
relieves stress

Chemical Synapses
+ Nervous impulses are electrical signals that travel along neurons.
+The electrical signals cannot travel from one neuron to the next directly.
+The signal crosses the gap between nuerons.This is called a synapse.
+From one nueron to another, like a domino effect, chemicals are released from the neurotransmitters in response to nerve impulses.
James Lange Theory
Emotions are not only mental, but physical. Bodily changes come first, than emotional changes.

EX: I see a bear. My muscles tense. My heart races. I am afraid.

Happiness
Happiness is an emotion that sparks pleasure and reward
There is an increase of
Dopamine and Serotonin.


In happiness, serotonins role is to ease stress and other tensions that could affect our mood negatively.

+Ventral Tegmental Area

Anger
Due to
imbalance in serotonin
, one can build up aggression causing one to become angry.
The flow of the blood increases activity in the
amygdala
(area in the brain that deals with emotions)
Once high blood flow reaches the amygdala, emotions such as anger and fear are activated.
Abnormalties
Defects in how your brain collects and processes the chemical neurotransmitters can have an immense effect of your emotions.
The lack of experiencing emotion often leads to cases of severe
depression
.
No Dopamine > Unhappy
No Serotonin > Cannot Regulate Normal Body Functions
