Biology

(Bio Psych)

Basically studying the

brain and it’s

biological properties

So let us figure out some

properties of our brains

Run your fingers through your scalp, and feel for bumps

and dents

Make a note of the location of the bumps, and dents

The Nervous System

If you think of the brain as a central computer that

controls all bodily functions

The nervous system is like a network that relays

messages back and forth from the brain to different

parts of the body.

Automatic Nervous System (ANS)

We are often unaware of the ANS because it functions

involuntary and reflexively

we do not notice when blood vessels change size or

when our heart beats faster.

However, some people can be trained to control some

functions of the ANS such as heart rate or blood

pressure

Parasympathetic

Sympathetic

Sympathetic Fight-or-Flight Response

It uses energy

your blood pressure

increases

your heart beats faster

digestion slows down

Parasympathetic

This calls for "Rest and

Digest" responses.

Now is the time for the

parasympathetic

nervous to work to save

energy.

This is when blood

pressure can decrease

pulse rate can slow

digestion can start

Forebrain Largest part of the brain

The cerebrum contains the information that essentially makes us who we are

intelligence, memory, personality, emotion, speech, and ability to feel and move

Specific areas of the cerebrum are in charge of processing these different types of information

These are called lobes, and there are four of them

the frontal, parietal, temporal, and occipital

Midbrain

Smallest area of the brain

Relay station for visual

and auditory information

Also plays a part in body

movement

Hindbrain

The hindbrain sits

underneath the back end

of the cerebrum, and it

consists of:

The cerebellum, pons,

and medulla

It also controls many of

the body's automatic

functions, like breathing,

heart rate, blood

pressure, swallowing,

digestion, and blinking
