Econometric Views (EViews)01:29

Econometric Views (EViews)

569
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...

Revisionist Views of Adolescent and Adult Cognition

294
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

5.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Levels of Communication II: Organizational, Public, and Group Dynamics

2.9K
Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

Visual System01:26

Visual System

1.7K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Area of Science:

  • Neuroscience
  • Computer Vision
  • Machine Learning

Background:

  • Human neuroimaging studies of visual perception use limited image sets (~100 images) due to experimental constraints.
  • Large-scale datasets and statistical learning have transformed machine vision, but not yet human visual neuroscience.
  • There is a need to increase image set sizes in neuroimaging to apply advanced statistical learning methods.

Purpose of the Study:

  • To introduce BOLD5000, a large-scale human functional MRI (fMRI) dataset for visual neuroscience research.
  • To significantly increase the number and diversity of images used in fMRI studies.
  • To bridge the gap between computer vision and human neuroscience by integrating diverse, real-world image datasets.

Main Methods:

  • Conducted a human functional MRI (fMRI) study using a slow event-related design.
  • Collected brain imaging data for nearly 5,000 distinct, real-world scene images.
  • Incorporated images from established computer vision datasets: Scene UNderstanding (SUN), Common Objects in Context (COCO), and ImageNet.

Main Results:

  • BOLD5000 dramatically increases the scale of image datasets used in fMRI studies.
  • The dataset's diversity allows for exploring neural representations across various visual features, categories, and semantics.
  • Enables fine-grained analysis of visual processing in the human brain.

Conclusions:

  • BOLD5000 facilitates the application of statistical learning approaches to human neuroimaging data.
  • The study advances the goal of a unified vision science, integrating biological and computer vision.
  • Provides a foundation for deeper understanding of neural representations of complex visual stimuli.
