How Neuroscience to Improve Latin American Identity with Fruição, Metacognition and First Person Consciousness?
Near-infrared spectroscopy (NIRS) and functional near-infrared spectroscopy (fNIRS) are non-invasive neuroimaging techniques used to measure changes in hemoglobin concentrations in the brain, specifically oxygenated hemoglobin (HbO) and deoxygenated hemoglobin (Hb), which are related to brain activity.
When conducting NIRS fNIRS studies with infants, researchers typically collect raw data from the NIRS/fNIRS device during experiments. This raw data contains the changes in light absorption by the brain tissue, which can be translated into changes in HbO and Hb concentrations.
To visualize and analyze the data, researchers can use various software tools specifically designed for NIRS/fNIRS data analysis. These software packages often provide real-time visualization options and multiple display modes to interpret the data. Some common display modes include:
Time-series plots: These plots show the changes in HbO and Hb concentrations over time. They allow researchers to observe the dynamics of brain activity during different tasks or stimuli.
Spatial maps: NIRS/fNIRS devices usually have multiple channels for data collection. Spatial maps illustrate the distribution of brain activity across different regions by displaying the concentration changes in a topographical format.
Event-related analysis: This mode allows researchers to align the data with specific events or stimuli presented during the experiment. It helps identify brain responses related to certain tasks or sensory inputs.
Connectivity analysis: Researchers can assess the functional connectivity between different brain regions by analyzing the correlations in HbO and Hb changes across channels.
Statistical analysis: Researchers often perform statistical tests to compare conditions or groups and determine significant differences in brain activity.
In addition to NIRS/fNIRS data, researchers might simultaneously collect EEG data and behavioral data during experiments. EEG (electroencephalography) measures electrical brain activity through electrodes placed on the scalp. By combining NIRS/fNIRS, EEG, and behavioral data, researchers can gain a more comprehensive understanding of brain function and its relation to behavior.
Neuroscience labs commonly use specialized software and programming environments (e.g., Analyzer, Satori, Aurora, NIRSLab, MATLAB, Python) to perform data analysis, statistical tests, and create visualizations. Each lab might have its preferred tools and pipelines, depending on the specific research goals and the expertise of the researchers.
Overall, NIRS fNIRS studies in infants and other populations contribute valuable insights into brain development, cognitive processes, and the neural basis of behavior. The combination of NIRS/fNIRS with other neuroimaging and behavioral measures provides a powerful approach to study brain function in diverse contexts.
