Performing a Simple Data Analysis using MS-Excel Function01:17

Performing a Simple Data Analysis using MS-Excel Function

1.1K
Microsoft Excel offers a suite of functions and tools ideal for statistical analysis, making it accessible to students and researchers. This article outlines fundamental Excel functions pivotal for data analysis.
SUM: This function calculates the total sum of a range of values. It's the foundation for aggregating data, essential for determining overall trends and totals in datasets.
AVERAGE: It computes the mean value of a given set of numbers, providing a quick insight into the central...

Adrenergic Receptors: ɑ Subtype01:31

Adrenergic Receptors: ɑ Subtype

3.0K
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...

Adrenergic Receptors: β Subtype01:26

Adrenergic Receptors: β Subtype

3.9K
β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors...

What is Behavior?00:54

What is Behavior?

10.3K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Diabetes Mellitus: Overview and Type I Subtype

5.5K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

How Data are Classified: Categorical Data01:11

How Data are Classified: Categorical Data

45.2K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Child Psychiatry

Background:

  • Executive functions (EF) are crucial for goal-directed behavior and are frequently impaired in children with neurodevelopmental disorders.
  • Significant heterogeneity exists in EF difficulties among children, even within diagnostic groups.
  • A data-driven approach is needed to identify distinct profiles of EF-related challenges.

Purpose of the Study:

  • To identify distinct clusters of children based on profiles of executive function (EF)-related difficulties.
  • To investigate the underlying neurobiological differences, specifically white matter connectivity, that distinguish these data-driven groups.

Main Methods:

  • Utilized community clustering on data from 442 children with reported attention, learning, or memory difficulties.
  • Applied a structural connectomics approach and partial least squares analysis to examine white matter connectivity.

Main Results:

  • Identified three distinct groups: (1) inattention/hyperactivity/impulsivity with poor EF, (2) learning problems, and (3) aggressive behavior/peer relationship issues.
  • These groups showed significant variations in white matter connectivity within the prefrontal and anterior cingulate cortices.

Conclusions:

  • Data-driven classification effectively identified stable groups of children with specific EF-related behavioral difficulties.
  • These distinct groups align with underlying neurobiological differences in brain connectivity.
  • This approach enhances understanding of interindividual variability in neurodevelopmental profiles.
