Análisis del cerebro: la neurobiología del día a día
1. ANÁLISIS DEL CEREBRO: LA NEUROBIOLOGÍA
DEL DÍA A DÍA

2. EXAMPLE OF EVERYDAY
NEUROBIOLOGY
A person sits in his favourite sofa and
turns on the television to watch his
favorite movie, during the movie there is
a scene that causes his crying.
3. PARTS OF THE NERVOUS SYSTEM
THAT ARE ACTIVE
Thalamus,
cerebral cortex
neocortex
occipital cortex
temporal lobe
chiasm
primary visual cortex
extrastriate cortex
4. EYE
Information from the eye, from the world has
to get through all of these various parts of the
eye. So information from the eyes is going to
come in through optic nerves. It may or may
not cross in the chiasm.
5. We'll look at that in a bit, and it's going to
end up being processed in primary visual
cortex back in the back of the brain, in the
occipital cortex. And from there, from the
medial surface here, where, where primary
visual cortex is, there are two basic
pathways. There's one that goes towards
the temporal lobe and then there's one that
goes more dorsally. And this dorsal
pathway tells us about where things are.
6. PERCEPTION
The extrastriate cortex is where
perception happens. Mostly on the
medial surface of the brain. And from
here, its information is going to go in two
basic pathways. A ventral stream and a
dorsal stream. A ventral stream is the
what pathway. And the dorsal stream is
the where pathway. Down in this ventral
stream, we figure out what things are. So,
we figure out what all these different lines
and, and edges and colors.
7. STIMULUS AND PERCEPTION
The stimulus is the wavelength, the
perception is the color. The stimulus is,
is something that happens either outside
of us and in general we're going to talk
about things that happen outside of us
rather than inside our body.
8. So we're talking about changes in light,
changes in sound waves, changes in
mechanical energy, touch, that kind of
thing. Well, and the output is perception
which depends on the cerebral cortex
neocortex. we have to go through
transduction. the light energy and that
sound energy, has to be changed into
neural energy. So we have to transform
the stimulus into electricity.
9. That signal then has to go through its
channels to reach the cerebral cortex.
Everything gets translated by the
thalamus and then sent to the cerebral
cortex. Finally, we have modulation.
This is where we interpret a stimulus of
cognitive form, example: good or bad,
happy or sad.
10. THE COURSE ALLOWED ME…
The course allowed me to be able to
interpret people and functions of their
nervous system. It helps me interpret
the symptoms of my patients in my
psychology career.
