• Physiological psychology seeks to describe the
  physical mechanisms of the body that mediate our
  behaviors.
• Physical movement
• Mental activity
• The Mind-Body Problem
• Two major views
• Dualism Mind and body are separate but
  interacting.
• Monism Mind is a property of a physical
  nervous system.
• Nature Vs. Nurture
• Intrinsic/extrinsic
• genetic/learned
• Inherited/acquired

Localization

• Notion that discrete brain regions control
  discrete behaviors
• Phrenology Notion that bumps on the skull
  indicate developed skills associated with regions
  of cortex
• Criticisms of Phrenology
• Descartes skull was labeled an idiot.
• Poor science
• Flourens (using ablation) brain damage did not
  always appear to alter behavioral functions

Brocas Area

• Brocas area
• Patient Tan showed major deficit in speech
• Termed aphasia
• After Tan died in 1861, Brocas autopsy noted
  damage in left hemisphere

Electrical Stimulation of Brain

• Luigi Galvani used electrical charge to induce
  muscle contraction
• Fritsch and Hitzig applied electrical stimuli to
  cortex in dog showed muscle contraction on
  opposite body side (notion of contralateral)
• Work was based on battlefield observations
• Penfields cortical stimulation studies (Montreal)

Behaviors Elicited by Electrical Brain
Stimulation

• Implant electrode into brain, administer
  electrical current observe behavioral change
• Feeding
• Drinking
• Sexual Behavior
• Reward and Aversion
• Locomotion

Human Evolution

• Cynodont -mammalian ancestor ca. 220 mya
• 65 mya Dinos became extinct.
• Most mammals nocturnal until then.
• Primates appeared- small, arboreal, mostly
  insectivores.
• Hominids- ca. 1.7 mya. In Africa
• Homo sapiens - ca. 100,000 mya
• coexisted ca. 10,000 years with Neanderthal.

Roots of western physio-psych

• ancient Egyptians importance of brain
• Later Mesopotamians, Hebrews and Greeks
• Aristotle-heart is seat of thought and soul
• View survived until 18th century.
• 3rd century Greeks
• Galen- ventricles of brain
• Dualism/monism-Descartes
