Introduction to BioPsych, the CNS, and three main structures of the brain

1. Psycho-
Biology
(Bio Psych)
Basically studying the
brain and it’s
biological properties

2. 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

4. 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.

7. 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

8. Sympathetic
 Fight-or-Flight Response
 It uses energy
 your blood pressure
increases
 your heart beats faster
 digestion slows down

9. 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

11. 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

13. Midbrain
 Smallest area of the brain
 Relay station for visual
and auditory information
 Also plays a part in body
movement

14. 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
