Biological Bases of Behavior

  • This unit of psychology includes brain imaging techniques, Neuroanatomy, organization of the nervous systems, neural transmission, the endocrine system, genetics and evolutionary psychology
  • The big question is the relationship between physiological processes and behavior—including the influence of neural function, the nervous system and the brain, and genetic contributions to behavior
  • Brain Scans include EEG, MRI, fMRI, PET, and MEG scans
  • Physical methods of changing the brain include surgery, ablation, lobotomy, lesioning, and deep brain stimulation
  • The central nervous system communicates via the brain/spinal cord and nerves
  • The endocrine system communicates via the blood stream and hormones

Biological Bases of Behavior

Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
