Slide 1-

The Origins of Neuroscience Prehistoric ancestors Brain vital to life Skull surgeries Evidence: Trepanation Skulls show signs of healing Views of ancient Egypt Heart: Seat of soul and memory (not the head)

The Origins of Neuroscience Views of the Brain: Ancient Greece Correlation between structure and function Hippocrates Brain: Involved in sensation; seat of intelligence Aristotle: Clung to the heart was the centwe of the intellect. Brain was a radiator that cooled the blood Tempered the seething heart

Slide 9-

The Origins of Neuroscience Views of the Brain: Renaissance to the Nineteenth Century Gyri, sulci, and fissures
Slide 10-

The Origins of Neuroscience Views of the Brain: The Nineteenth Century Central subdivision: brain and spinal cord Peripheral division: network of nerves coursing through the body

Slide 19-

The Origins of Neuroscience Localization of Function in the Brain (Cont’d) Regional specialization in different species
Slide 20-

The Origins of Neuroscience Evolution of the Nervous System Natural selection Nervous systems of different species may share common mechanisms Rationale for “animal models”
Slide 21-

The Origins of Neuroscience The Neuron: The Basic Functional Unit of the Brain Cell theory Cells Nerve cells
Slide 22-

Neuroscience Today Reductionist approach Levels of analysis Molecular Cellular Systems Behavioral Cognitive
Slide 23-

Neuroscience Today The Neuroscientist -Education, Training, Research experience -Clinical vs. Experimental research
Slide 24-

Neuroscience Today Scientific Process Observation Replication Interpretation Verification
Slide 25-

Neuroscience Today The Use of Animals in Neuroscience Research Animals: Renewable natural resources The more basic the process under investigation, the more distant the evolutionary relationship with humans Examples (from simple to more complex) - nematodes, insects, snails, squid, rodents, monkeys, etc.
Slide 26-

Neuroscience Today The Use of Animals in Neuroscience Research (Cont’d) Role of animal welfare societies Neuroscientists accept certain moral responsibilities Ensure that experiments are worthwhile and well planned Eliminate or minimize pain and distress to the animal All possible alternatives must be considered first
Slide 27-

Neuroscience Today The Use of Animals in Neuroscience Research (Cont’d) Animal rights Philosophy Abolition of animal use Animal rights activists
Slide 28-

Neuroscience Today The Cost of Ignorance: Nervous System Disorders
Slide 29-

Concluding Remarks Goal of neuroscience:To learn how the nervous system functions Brain’s activity reflected in behavior Computer-assisted imaging techniques New treatments for nervous system disorders Non-invasive methods Experiments in live tissue
