Hello everyone! Welcome to advanced neurobiology! Neuroscience is a wonderful branch of science on how our brain perceives the external world, how our brain thinks, how our brain responds to the outside of the world, and how during disease or aging the neuronal connections deteriorate. We’re trying to understand the molecular, cellular nature and the circuitry arrangement of how nervous system works. Through this course, you'll have a comprehensive understanding of basic neuroanatomy, electral signal transduction, movement and several diseases in the nervous system. This advanced neurobiology course is composed of 2 parts (Advanced neurobiology I and Advanced neurobiology Il). They are related to each other on the content but not on scoring or certification, so you can choose either or both. It’s recommended that you take them sequentially and it’s great if you’ve already acquired a basic understanding of biology. Thank you for joining us!

So this lecture we'll talk about Mood and Mood Disorder.

So what is mood and what is emotion?

Sometimes people can confuse these two concepts together.

An emotion refers to a state or

an event caused by a specific target and

it could be very brief in duration, can last only seconds or minutes.

And they're usually very, very specific.

For example, anger, fear, sadness, or happiness.

And usually the emotion comes with the very distinct facial expression.

We have very different facial expressions between sadness and

happiness, for example.

And sometimes the emotion can be action oriented.

That means we under certain emotion people plan to do something.

The cause of the mood is often very general or sometimes can be unclear and

it lasts much longer than the emotion.

It can last for hours and days.

And compared to the emotion, the mood is more general.

It can be positive or it can be negative.

And it's generally not indicated by distinct facial expression.

So, if you are under some kind of mood,

normally you don't have very typical facial expression for that mood.

It's cognitive in nature.

Meaning, thinking or

brooding can affect the mood.

So the spectrum of mood and emotion,

it can span from the happiness to disgust.

And we can clarify the emotion or the mood into positive emotion or

positive mood and negative emotion and mood,

and mood states generally grouping of this state.

And if we look at the sources of emotion and

moods, we can see there are several sources.

One is the time of the day, or the time of the week.

So, statistically, we have the highest positive, the blue line

is the positive mood or emotion, or the dark, the black line, is the negative one.

So statistically, we have the happiest time during Saturday,

and the lowest time happened on Sunday.

You have the highest negative emotion and lowest the positive emotion.

So maybe people predict the Monday is coming.

So the Sunday is the saddest day and Saturday is the happiest day.

So other sources other than the time of the day and

the week, so the weather, so weather can affect mood a lot.

But there's no impact according to a very restricted research.

And then there's a stress.

There's study saying increase of stress can

affect our moods in a social activity and also sleep.

Better sleep can help you to have more positive mood and emotion.

And the more sources exercises, and

people say if you have physical exercises, you have a better mood.

The exercises can help you produce more endorphin,

which can activate your reward

pathway that we'll talk about later in the mood disorder section.

And age, so older people experience more,

express negative emotion less frequently.

So older people are happy people.

Gender, women show more emotional expression.

Women experience emotion more intensely than men and

display more frequently expression of emotion.
