Study Notes
Behavioral Neuroscience
- The scientific study of how brain activity influences behavior
- Involves both overt and covert behaviors
- Also considers the influence of environmental factors and life experiences
Key Areas of Behavioral Neuroscience
- Cognitive Neuroscience: Focuses on brain processes related to reasoning, problem-solving, memory, and attention.
- Affective Neuroscience: Focuses on neurobiological processes underlying emotions.
- Social Neuroscience: Focuses on the neurobiological basis of social behaviors like empathy, affiliation, and morality.
- Decision Neuroscience: Focuses on the neurobiological basis of choice behavior, also known as neuroeconomics.
Levels of Analysis in Brain-Behavior Relationships
- Cellular Level: Examines how individual cells in the brain (neurons) contribute to behavior. For example, the degeneration of gatekeeper cells can contribute to Alzheimer's disease.
- Systems Level: Analyzes how networks of neurons, known as brain areas, work together to produce behavior. For example, researchers identified networks in the entorhinal cortex that are involved in representing time in rats.
- Cognitive Level: Focuses on higher-level mental processes and how brain activity is related to them. For example, interpreters have hyperconnectivity between their frontal lobes compared to bilingual individuals without language interpretation skills.
- Social Level: Investigates how brain activity relates to social interactions and behaviors. For example, research suggests that prosocial behavior in adolescents is associated with activity in the anterior cingulate cortex.
Genetics and Behavior
- Genetics plays a role in shaping behavior by influencing the development and function of the brain.
Measuring and Manipulating Brain Activity
- Electrophysiological Measurements: Tiny electrodes are inserted directly into neurons to record their electrical activity.
Brain Imaging Techniques
- Functional Magnetic Resonance Imaging (fMRI): Uses MRI technology to detect oxygen usage by neurons. This allows for inferences about brain function.
- Positron Emission Tomography (PET): Detects glucose consumption by neurons to infer brain function.
- Electroencephalography (EEG): Measures electrical activity in the brain by detecting differences in emitted energy. This can be used to study brain function.
- Event-Related Potentials (ERP): Measures small voltage changes, called waveforms, in brain areas responsive to specific events or stimuli.
- Magnetoencephalography (MEG): Measures magnetic fields emitted from brain activity to infer brain function.
Studying Brain Damage and Structural Imaging
-
Traumatic Brain Injury: Injury caused by a blow to the head or an object penetrating the skull.
-
Structural Brain Imaging: Techniques used to detect brain injury.
-
Magnetic Resonance Imaging (MRI): Creates images of any body part using a powerful magnetic field and resonant frequency emissions.
-
Computed Tomography (CT): Takes X-ray images from multiple angles and uses a computer to produce cross-sectional images, allowing for the examination of deep brain structures.
Techniques to Manipulate and Measure Brain Activity
- Manipulation Techniques: Techniques that alter brain structure or function to observe their impact on behavior.
- Lesions: Damage or removal of brain tissue.
- Brain Stimulation: Applying electrical or magnetic stimulation to specific brain areas.
- Temporary Inactivation: Using drugs or other methods to temporarily disable specific brain areas.
- Measurement Techniques: Methods for recording and measuring brain activity.
- Functional Magnetic Resonance Imaging (fMRI): Measures brain activity by detecting oxygen usage.
- Positron Emission Tomography (PET): Measures brain activity by detecting glucose consumption.
- Electroencephalography (EEG): Measures electrical activity in the brain.
- Event-Related Potentials (ERP): Measures small voltage changes in response to stimuli.
- Magnetoencephalography (MEG): Measures magnetic fields generated by brain activity.
Origins of Behavioral Neuroscience
- Ancient Views: Ancient civilizations often attributed behavior to supernatural forces.
- Philosophical Roots: Philosophers like Hippocrates and Aristotle recognized the brain's role in behavior.
- Localization of Function: The idea that specific brain areas control specific functions emerged gradually through observations and experimentation.
Key Concepts in Evolution and Behavioral Neuroscience
- Natural Selection: The process by which organisms with advantageous traits survive and reproduce more successfully, passing those traits to their offspring.
- Exaptation: The adaptation of a trait for a function different from the one for which it originally evolved.
Examples of Brain Evolution and Behavior
- Bird Song: Changes in brain structures, such as the HVC region, are related to the complexity and production of birdsongs, which are used for attracting mates and defending territory.
- Food Storage in Birds: Food-storing birds have larger hippocampi, which are involved in spatial memory, compared to birds that do not store food. This demonstrates how brain structures can evolve in response to environmental demands.
