Fruit Development, Structure, and Function

Fruit Development, Structure, and Function

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Stream Function

Stream Function

In two-dimensional incompressible fluid flow, the continuity equation is essential for ensuring mass conservation, meaning that any change in fluid entering or exiting a region is balanced by a corresponding change elsewhere. For incompressible flow, where density remains constant, this requirement simplifies to the condition that the divergence of the velocity field must be zero. Mathematically, this is expressed as,

Structural Protein Function

Structural Protein Function

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Seed Structure and Early Development of the Sporophyte

Seed Structure and Early Development of the Sporophyte

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

Summary

This summary is machine-generated.

Population receptive fields (pRFs) in the human lateral visual stream develop from childhood to adulthood, refining spatial coding. Early structural organization is stable, but pRFs fine-tune visual field coverage and spatial precision.

Area of Science:

Neuroscience
Developmental Neuroscience
Visual Perception

Background:

The human visual cortex has multiple processing streams, including the lateral visual stream crucial for shape and motion perception.
The development of population receptive fields (pRFs) and their impact on spatial coding in this stream from childhood to adulthood remains largely unexplored.

Purpose of the Study:

To investigate the developmental trajectory of pRFs in the lateral visual stream (V1 to LO and TO maps) from childhood to adulthood.
To understand how pRF development influences spatial coding and visual field representation.

Main Methods:

Utilized functional magnetic resonance imaging (fMRI) and pRF modeling in school-age children and adults.
Analyzed topographic organization, cortical folding relationships, and pRF properties within the lateral visual stream.

Main Results:

Lateral visual stream topography is stable after age five, with the middle occipital gyrus linking LO and TO map transitions.
pRFs in LO and TO maps show differential development, expanding central visual field coverage in LO and peripheral in TO.
Adults exhibit improved spatial decoding from LO and TO responses compared to children due to refined pRFs.

Conclusions:

The fundamental structural-functional organization of the lateral visual stream is established early in development.
Fine-scale properties, including pRF distribution and spatial precision, are progressively refined throughout childhood.
These findings enhance our understanding of human visual system development and provide a basis for studying developmental disorders.
