Study Notes
The Brain's Role in Behavior
- The brain's primary function is to control behavior.
- This behavior is categorized into three components: Affect, Behavior, and Cognition.
- Affect encompasses emotions, feelings, values, arousal, and motivational intensity.
- Behavior encompasses all forms of movement.
- Cognition refers to memory, reasoning, thinking, and perception.
- These components work together to guide behavior essential for survival, such as obtaining food, staying safe, and reproduction.
The Brain as a System
- Behavioral neuroscience aims to understand the physiological processes that control behavior.
- This understanding involves recognizing the connections between the body and brain, as well as the connections within different brain regions.
- These functional connections form "systems".
System Function
- Systems operate by processing input and generating an output.
Historical Perspectives on the Brain and Behavior
- Dualism: The belief that the body is physical, but the mind (or soul) is not.
- Monism: The belief that the universe consists only of matter and energy, and the mind is a product of the nervous system
Timeline of Key Discoveries in Neuroscience
- 1700 BC: Egyptians recognize the brain's existence while attributing the seat of the soul to the heart.
- 460 BC: Hippocrates proposes the brain as the center of thought and emotion.
- 1645: Rene Descartes suggests the brain as a sensory organ for the soul, providing information for the soul's decision-making.
- 1780: Luigi Galvani demonstrates that electrical stimulation can trigger muscle movement in dead frogs.
- ~1840: Johannes Müller establishes that nerve message characteristics depend on the sense organ.
- 1815: Pierre Flourens pioneers experimental ablation to show the specific functions of different brain regions.
- 1861: Paul Broca studies brain lesions in patients and discovers that frontal lobe damage can cause speech impairment.
- 1870: Hermann von Helmholtz discovers that nerve signal conduction is slower than anticipated, revealing the presence of chemical messaging in neurons.
- 1849: Gustav Fritsch and Eduard Hitzig identify the motor cortex through electrical stimulation of specific brain regions, demonstrating its role in movement.
