9. 9
The Biological Perspective: Central Nervous System
10. 10

Norepinephrine
Serotonin
11. 11
12. 12
13. 13
Measuring the Brain
Electroencephalography (EEG)
Positron Emission Tomography (PET)
Computerized Tomography (CT)
Magnetic Resonance Imaging (MRI)
Functional Magnetic Resonance Imaging (fMRI)
14. 14
Lateralization
Lateralization:
The study of brain functioning that differentiates the left hemisphere from the right hemisphere
While both hemispheres appear symmetrical in size and shape, both have varying brain functions
15. 15
The Biological Perspective: Peripheral Nervous System
Peripheral Nervous System (PNS):
A network of nerve fibers leading from the CNS to all parts of the body
Somatic Nervous System (SNS):
Senses and acts on the external world
Relays to the brain information picked up through the sense organs, and transmits the messages to the skeletal muscles
16. 16
The Biological Perspective: Peripheral Nervous System
Autonomic Nervous System (ANS):
Sympathetic Division:
mobilizes the body to meet emergencies
Parasympathetic Division:
slows down metabolism and regulates the organs in such a way that they can do the work of rebuilding their energy supply
17. 17
The Biological Perspective: Endocrine System
Hormones:
Chemical messengers that are released into the bloodstream by the endocrine glands
Affect sexual functioning, appetite, sleep, physical growth and development, the availability of energy, and emotional responses
18. 18
Evaluating the Neuroscience Perspective:
The neuroscience perspective does not hold the absolute answer to causality
Not all mental illness can be traced to an organic basis
Ethical issues surface around treatment approaches and concerns
19. 19
Integrating the Neuroscienceand Psychological Perspectives
Integrating the Neuroscience and Psychological Perspectives:
Emphasis in combining both perspectives might hold new answers to understanding psychopathology
Evidence suggests that the environment can alter brain functioning
Advances in brain studies offer promising new avenues of research
20. 20
Integrating Neuroscience and Psychodynamic Perspectives
Integrating Neuroscience and Psychodynamic Perspectives:
Psychoanalysis has waned and lost its popularity in recent years
Methods used in psychoanalysis are not objective while neuroscience is more detailed
Combining both perspectives may hold new keys to understanding development and psychopathology
21. 21
Integrating Neuroscience and Cognitive-Behavioral Perspectives
Integrating Neuroscience and Cognitive-Behavioral Perspectives:
Combining both perspectives might improve the understanding of psychopathology
Applications to depression, mania, emotion, personality
Research surrounding the Behavioral Approach System or Activation System (BAS)
22. 22
