What is a Sensory System?01:31

What is a Sensory System?

101.2K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

Gene Therapy00:59

Gene Therapy

27.6K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Sensory Modalities01:15

Sensory Modalities

3.9K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Sensory Memory01:14

Sensory Memory

701
Sensory memory captures information from the environment in its original form for a very brief duration, just long enough to be exposed to visual, auditory, and other senses. This type of memory is detailed and rich but quickly lost unless certain strategies are employed to transfer it into short-term or long-term memory. Sensory information is continuously bombarding the human brain, yet only a small fraction is absorbed, as most of it does not significantly impact daily life. For instance,...

Group Therapy01:26

Group Therapy

450
Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Introduction to Sensory Receptors

8.1K
Sensory receptors are vital in our ability to perceive and interpret the world. Sensory receptors are specialized cells in the peripheral nervous system that respond to various stimuli and enable one to experience different sensations. Based on specific criteria, sensory receptors are classified into distinct types.
The first classification criterion is based on cell type, position, and function. Some receptor cells are neurons with free nerve endings, where their dendrites are embedded in the...

Summary

Early sensory stimulation after ischemic stroke shows varied effects, from neuroprotection to increased infarct size. More research is needed to understand its role in functional recovery during acute treatment.

Area of Science:

  • Neuroscience
  • Neurology
  • Stroke Research

Background:

  • Cortical activation aids functional recovery post-stroke.
  • The impact of early sensory stimulation (within 6 hours of stroke onset) remains largely unknown.
  • Preclinical studies show conflicting results on acute sensory stimulation's effects on brain injury.

Purpose of the Study:

  • To review the current knowledge on acute sensory stimulation's effects on stroke outcomes.
  • To identify gaps in understanding and propose future research directions.

Main Methods:

  • Literature review of preclinical and clinical studies on sensory stimulation in acute stroke.
  • Discussion of the relevance of sensory stimulation during emergency medical services, acute treatment, and intensive care.

Main Results:

  • Preclinical data suggest sensory stimulation can either protect the brain or worsen infarct volume (30-50% increase).
  • Lack of systematic knowledge hinders clinical application.
  • Patients experience uncontrolled sensory input during critical phases of stroke care.

Conclusions:

  • Understanding the precise effects of acute sensory stimulation is crucial for optimizing stroke patient care.
  • Further experimental and clinical trials are necessary to establish evidence-based guidelines for sensory stimulation in acute stroke.
