Part 3: Biological Foundations
Sept. 29 –
Oct. 10
You
can have a brain and not have a mind, but you can't have a mind without a
brain… The
information provided in this section reflects the role of neurological science
as a cornerstone for psychology and will be relevant for every other section of
the course. “States
of consciousness” will be discussed in relation to the biological
underpinnings.
Chapter
4, Biological foundations of behavior: Evolution, genes, and brain
(Sept. 29 – Oct. 3)
Chapter
6, States
of consciousness (Oct. 6 – 8) pages 169-192 only

PRE-LAB #3: The Brain

Part III: Biological
Foundations
Nervous and endocrine
systems
I. Introduce the structure of the nervous system
 | Central and Peripheral
 | Branches of the peripheral n.s. (Somatic and Autonomic
(sympathetic and parasympathetic))
|
|
 | Principles governing the central nervous system (CNS)
 | Spinal cord reflexes to illustrate principles
1. Central coordination of opposing actions.
2. Complicated behaviors are created by the coordination of simpler
ones.
3. Feedback systems ensure smooth functioning.
4. Normal behavior reflects coordination of actions by several levels
of the CNS.
|
|
 | Structure of the brain (click
here for overheads and explanations)
 | Hindbrain inc. brain stem structures (medulla,
pons), cerebellum, and most
of the reticular activating system.
|
 | Midbrain (mesencephalon), mostly geared toward
relaying sensory and
motor information.
|
 | Forebrain (diencephalon and
telencephalon).
Diencephalon includes thalamus and
hypothalamus; Telencephalon includes the cerebrum and
cerebral cortex.
|
 | Lobes of the cerebral cortex: Frontal (inc. motor),
Parietal (inc. sensory), occipital,
and temporal.
|
 | Limbic system, lying between
di- and telencephalon. Area focused on emotions
containing amygdala, hippocampus, among other
structures.
