Naturalistic Observations02:30

Naturalistic Observations

17.0K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Diffusion01:12

Diffusion

216.5K
Diffusion is the passive movement of substances down their concentration gradients—requiring no expenditure of cellular energy. Substances, such as molecules or ions, diffuse from an area of high concentration to an area of low concentration in the cytosol or across membranes. Eventually, the concentration will even out, with the substance moving randomly but causing no net change in concentration. Such a state is called dynamic equilibrium, which is essential for maintaining overall...

Diffusion

6.3K
Diffusion is a type of passive transport. In passive transport, a substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. For example, take the diffusion of substances through the air. When someone opens a perfume bottle in a room filled with people, the perfume is at its highest concentration in the bottle and is at its lowest at the edges of the room. The perfume vapor will diffuse, or spread away, from the...

Econometric Views (EViews)

566
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

4.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Behavior of Gas Molecules: Molecular Diffusion, Mean Free Path, and Effusion

31.2K
Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many different directions before reaching the desired target. At room temperature, a gaseous molecule will experience billions of collisions per second. The mean free path is the average distance a molecule travels between collisions. The mean free path increases with decreasing pressure; in general, the mean free path for a gaseous molecule will be...

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Cognitive Science

Background:

  • Traditional brain imaging often uses simplified stimuli, not reflecting real-life sensory complexity.
  • Naturalistic stimuli, like movies, present rich, concurrent sensory information demanding advanced imaging and analysis.

Purpose of the Study:

  • To develop and validate a platform for naturalistic brain mapping using passive movie viewing and high-density diffuse optical tomography (HD-DOT).
  • To investigate the brain's synchronized cortical responses to complex, naturalistic audiovisual stimuli.

Main Methods:

  • Utilized high-density diffuse optical tomography (HD-DOT) to image healthy young adults during free viewing of a feature film.
  • Extracted visual and auditory features from the movie stimulus to correlate with observed cortical responses.
  • Analyzed synchronized cortical activity across visual and auditory processing areas.

Main Results:

  • Observed reproducible and synchronized cortical responses in a majority of the field-of-view during movie viewing.
  • Responses were most prominent in hierarchical cortical areas involved in visual and auditory processing.
  • Demonstrated sensitivity of HD-DOT to evoked responses and the utility of feature-based decomposition for mapping stimulus processing, including speech.

Conclusions:

  • HD-DOT is a sensitive tool for brain activity measurement during naturalistic audiovisual stimulation.
  • Feature-based analysis allows for functional mapping of complex naturalistic stimuli processing in the brain.
  • This approach provides insights into real-life sensory processing and neural synchronization.
