Reflexive space. In the area of mathematics known as functional analysis, a reflexive space is a locally convex topological vector space for which the canonical evaluation map from into its bidual (which is the strong dual of the strong dual of ) is a homeomorphism (or equivalently, a TVS isomorphism ). A normed space is reflexive if and only ...
The reflex — also known as the startle reflex — reaches a peak when your baby reaches 1 month and begins to disappear when they turn 2 months old. Several things may set off this reflex: a ...
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain. The brain will receive the input while the ...
The palmar grasp reflex (or grasp reflex) is a primitive and involuntary reflex found in infants of humans and most primates. When an object, such as an adult finger, is placed in an infant's palm, the infant's fingers reflexively grasp the object. [1] Placement of the object triggers a spinal reflex, resulting from stimulation of tendons in ...
ATNR is an acronym that stands for asymmetrical tonic neck reflex. It’s a primitive reflex that babies exhibit and is part of the development of muscle tone, consistent one-sided movements with ...
A reflex is a response to a stimulus and that occurs without conscious thought. Examples of adult reflexes include pulling your hand away from a hot stove and jerking your lower leg when the area ...
Purkinje images are reflections of objects from the structure of the eye. They are also known as Purkinje reflexes and as Purkinje–Sanson images. At least four Purkinje images are usually visible in the normal eye. The first Purkinje image (P1) is the reflection from the outer surface of the cornea. The second Purkinje image (P2) is the ...
The March of Progress, [1] [2] [3] originally titled The Road to Homo Sapiens, is an illustration that presents 25 million years of human evolution. It was created for the Early Man volume of the Life Nature Library, published in 1965, and drawn by the artist Rudolph Zallinger . It has been viewed as a picture of the discredited theory ...
