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!

This generation is very special.

In just one generation they can fly to Mexico.

[FOREIGN]

sensory

information

including

the

light

[FOREIGN],

OK?

[FOREIGN] Okay?

[FOREIGN] It's really special,

so they take a flight,

like a cycle.

[FOREIGN] Right,

so [INAUDIBLE]

it's important for

everything, right?

And also of course, this one, this special [INAUDIBLE] for this.

Just take a look.

This is a moth, this is a female.

[FOREIGN] When you turn on the fan [FOREIGN].

You can see, actually, this male actually smells something there, right?

And then this guy came, approached the female, okay?

So it's definitely based on the sensory information.

Okay, so if you can find this guy.

What kind of information does the male base on to find the female?

What's the information?

What kind of cue?

>> Chemical.

>> What?

>> Chemical. >> Chemical.

Okay, yeah that's possible right.

Maybe the thing you turn on, like a funnel.

[FOREIGN] A female, is she a chemical?

[FOREIGN]

Concentration?

Okay.

Right.

[FOREIGN] The chemical,

the [FOREIGN]

you got, grade in and

concentration and grade in.

[FOREIGN] Based

on ingredient.

[FOREIGN] Wow, yeah,

this male can seed

a female [FOREIGN]

To demo is really

a chemical detection.

[FOREIGN]

Okay.

[FOREIGN] It's clear,

describe base on their

chemo reception to detect

the The Now

there are many sensory modalities actually in different animals.

Actually they're quite different.

For example, this infrared detection [FOREIGN], okay.

In human we don't have.

But actually for this guy, for the snake,

they can detect the infrared light.

[FOREIGN] infrared detection.

[FOREIGN]

[FOREIGN]

Of

course.

Based on this information,

you already know.

The spatial information actually,

since spatial resolution

is not high [FOREIGN]

All right, so here is just some demonstration of the sensory system.

They're really important for the animals' survival and also for the reproduction.

For animal species, of course.

Most important thing, actually, you need survival.

[FOREIGN] The second one is reproduction.

[FOREIGN] Right?

[FOREIGN] Right?
