Psyc201 Test 1, Week 1 Flashcards
Aristotle
Believed the heart was responsible for sensations and thought, not the brain.
Galen (150-200 AD)
Attributed the “rational soul” to the brain’s ventricles, the “passionate soul” to the heart, and the “appetitive soul” to the liver.
Andreas Vesalius (1500-1540)
Detailed anatomist who placed the brain as the seat of all thought, feeling, and action.
Luigi Galvani (1737-1798)
Discovered that the brain uses electricity to function.
Franz Gall (1758-1828)
Developed phrenology, the idea that different brain areas have different functions and grow with use, creating bumps on the skull. (Incorrect, but introduced the concept of localization)
Phineas Gage (1848)
Survived a traumatic brain injury that significantly changed his personality, providing early evidence for brain localization of function.
Pierre Paul Broca (1824-1880)
Identified Broca’s area, a region in the brain responsible for language production, through patient studies.
Dualism (Descartes)
The belief that the brain and mind/soul are separate entities.
Monism/Materialism
The belief that the brain and mind are two manifestations of the same physical substance.
Functionalism
The mind carries out functions, which are implemented by the brain (brain as hardware).
Wilhelm Wundt (1879)
Established the first psychology lab.
Hermann Ebbinghaus (1885)
Conducted the first studies of memory.
William James (1890)
Wrote the first psychology textbook.
Localized Processing
The idea that different parts of the brain perform distinct functions.
Distributed Processing
The concept that cognitive functions involve networks of brain regions working together.
Default Mode Network (DMN)
A functional brain network active during internally focused thought and rest.
Genetic Influence on Brain
Genes play a crucial role, but most mental disorders involve genetic variations that increase risk, not single gene mutations.
Prenatal Factors
Factors like maternal infections during pregnancy can influence fetal brain development and increase the child’s risk of mental health disorders.
Pre-Prenatal Factors
Environmental exposures across generations (e.g., maternal alcohol use) can affect offspring brain development and behavior.
Environmental Influences on Brain
Numerous factors like pollution, urbanicity, peer support, nutrition, and socioeconomic status shape brain development.
Neurotransmitters
Chemical substances that neurons use to communicate with each other.
Cerebellum
A brain region containing a large number of neurons, important for motor control and cognition.
Number of Neurons in Brain
The brain contains 86 billion neurons (estimate), 16 billion in the cerebrum, 69 in the cerebellum, 1 in the brain stem
