3 days ago · His paper "The Reflex Arc Concept in Psychology", published in 1896, is regarded as the first major work in the (Chicago) functionalist school of psychology. A Review of General Psychology survey, published in 2002, ranked Dewey as the 93rd-most-cited psychologist of the 20th century.
4 days ago · A reflex arc can be defined as the complete pathway taken by the nerve impulses in order to facilitate a response during a reflex action. These responses are governed by the spinal cord but the impulses also reach the brain. The Reflex arcs are involuntary in nature based on the training and habits of an individual.
Jul 4, 2024 · In a two-neuron arc, simple reflexes are prompt, short-lived, and automatic and involve only a part of the body. Examples of simple reflexes are the contraction of a muscle in response to stretch, the blink of the eye when the cornea is touched, and salivation at the sight of food.
Jul 2, 2024 · When a subject is looking straight ahead and a bright light appears in the periphery of his or her field of vision, the subject’s eyes automatically turn to fix on the light; this is called the fixation reflex. The sensory pathway in the reflex arc leads as far as the cerebral cortex, because removal of the occipital cortex (the ...
Jun 22, 2024 · brainstem (brain stem) reflexes are involuntary motor responses originating in the brainstem. these reflexes are mediated by neural circuits that bypass higher cortical centers, enabling rapid, automatic responses. clinically, they are used to: assess the integrity of the brainstem and cranial nerves.
Jul 3, 2024 · The reflex arc is the neural pathway that reflex activity follows. For example when we inadvertently touch something hot, we experience the reaction arc. The receptor detects the change in temperature first. The electrical impulses are then delivered to the relay neuron in the spinal cord.

The Stretch Reflex Resists the Lengthening of a Muscle. Local Spinal Circuits Contribute to the Coordination of Reflex Responses. The Stretch Reflex Involves a Monosynaptic Pathway
