Document Summary
Neuroscience: study of the brain and the nervous system. Humans begin to age when large numbers of cells stop replication. States that cellular life and death determine the aging and time of death of human beings. Testing behavior of patients with damage to certain parts of the brain. Patients with localized brain damage often have loss of some particular function. Neurophysiological approach involves researchers making assumptions based on information about normally functioning brain from damaged brain. Recording electrical brain activity through multiple electrodes attached to surface of scalp. Use eeg"s to learn about activity of the human brain during certain states and certain behavioral tasks + make predictions about effect of brain injuries and types of seizures. Refined technique of even related potentials to timelock eeg activity. Not the best technique to find out where an event takes place because of the thickness of the skull diluting electrical signals. Lesioning targeting specific brain area and observing effects on the behavior.
