Study Notes
Techniques for Measuring Brain and Body Activity
- Change in blood volume using sound waves: This technique is known as Doppler ultrasound.
- TMS: Stands for Transcranial Magnetic Stimulation, a non-invasive method to stimulate neurons in the brain.
- Scalp electrodes for brain activity: Use Electroencephalography (EEG) to measure electrical activity of the brain through electrodes placed on the scalp.
- Type of potential measured by EEG: Measures event-related potentials (ERPs), which reflect brain responses to specific stimuli.
- EMG: Stands for Electromyography, which records electrical activity in muscles.
- Technique for measuring eye movements: Known as eye tracking, allows for the study of visual attention and ocular behavior.
- SCL: Stands for Skin Conductance Level, which measures changes in sweat gland activity indicating autonomic response.
- EKG: Measures Electrocardiogram, recording the electrical activity of the heart.
Surgical and Imaging Techniques
- Purpose of stereotaxic surgery: Allows for precise targeting of brain regions for research or treatment purposes.
- Invasive method for electrical activity recording: Intracranial electrodes are used, inserted directly into the brain tissue.
- Research method with radio-opaque material: Contrast imaging involves using contrast agents to visualize specific structures in brain imaging.
- Technique for interconnectivity in the brain: Diffusion Tensor Imaging (DTI) reveals the connections between different brain regions.
- PET: Stands for Positron Emission Tomography, an imaging technique that shows metabolic processes in the brain.
- Hydrogen atom wave measurement: Nuclear Magnetic Resonance (NMR) is utilized in imaging techniques, particularly fMRI.
- Rapid diffusion of water molecules method: Diffusion imaging helps analyze the movement of water in biological tissues.
- Advantageous imaging technique over PET: Functional MRI (fMRI) offers better temporal resolution of brain activity.
- Functional MRI signals: Known as BOLD (Blood-Oxygen-Level Dependency) signals, reflecting changes in blood flow related to neural activity.
- Slow technique for neural activity: Although sophisticated, PET can be too slow for capturing real-time neural dynamics.
- Three-dimensional brain tract imaging technique: DTI provides detailed maps of brain tracts, showing connectivity within the brain.
- Purpose of injecting 2-deoxyglucose in PET scans: It helps visualize metabolic activity in brain regions, aiding in the assessment of brain function.
Molecular and Genetic Techniques
- Locating specific neuroproteins in brain slices: Immunohistochemistry is used to identify and visualize proteins in tissue sections.
- Purpose of in situ hybridization: This technique detects specific RNA sequences, allowing for visualization of gene expression in tissue.
- Genetic information insertion into mice method: Transgenic mouse technology is employed to study gene functions and disorders.
- Purpose of CRISPR/Cas9 method: This gene-editing technology allows for targeted modifications in DNA, facilitating genetic research and therapy.
- Function of green fluorescent protein in the brain: GFP serves as a marker for gene expression and tracking cellular processes.
- Purpose of optogenetics: Enables precise control of neuronal activity using light, offering insights into neural circuits and behavior.
Psychological Assessments and Brain Functions
- Test for assessing intelligence: IQ tests measure cognitive abilities and intelligence levels.
- Test for assessing memory: Memory assessments evaluate recall and recognition capacity.
- Test for language and lateralization: Language assessments investigate language comprehension and production abilities.
- Purpose of the default mode network: Facilitates internal thought processes such as daydreaming, self-referential thought, and retrieval of past experiences.
