Physiological Psychology Introduction: Physiology Psychology describes or evaluates mechanisms for behavior. Behavior in its simplest definition is movement. These movements are muscular contractions which are recognizably different, yet performed publicly which makes it easy to study behavior between species. A species physiology must be compatible to its place in nature to secure survival. . What are some of these Physiological issues Identity problem- does ? Brain=behavior?

Techniques of Studying the Brain Lesion or Abrasion methods- cutting, severing, or destroying a part of the brain. How does it effect behavior? Used on animals-Not on humans except after the fact After WWI many men who had suffered brain injuries were studied. Links:http://www.bic.mni.mcg ill.ca/ Stimulation methods - extensively used- electric stimulation, electrode implants. Stimulation to certain parts of brain have been shown to cause: aggression, submission, and extreme sexual pleasure . Science Fiction has already explored some concerns of using stimulation to reward or punish humans.

Techniques for Studying the Brain Chemical Stimulation - A cannula, small tube, is inserted into the brain and crystalline forms of neurotransmitters are introduced. Recording Technique- Measures the activity of neurons. Recorder is inserted into axon. Electrode stimulates cell’s activity. Example-EEG- electroencephalogram. Biochemical Technique- used to map out various neurotransmitter systems. Example- How levels of transmitters is linked to depression. Drug therapy can alter these levels. Imaging Technique- New-Uses forms of energy and computers to create detailed pictures of the brain. Example-MRI (magnetism), CAT Scan (X- rays), and PET Scan (metabolic activity).

Neurons The Basic Unit of the Nervous System Estimated 10-12 billion or higher! Large number of neurons= more complex nervous system. One Neuron can connect to as many as 75 more neurons. Pyramidal neuron located in Hippocampus. Three Types of Neurons: Afferent or Sensory- run from sense organs to central nervous system. Efferent or motor- run from the
