Adult Stem Cells01:33

Adult Stem Cells

33.4K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Co-activators and Co-repressors

8.4K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

tRNA Activation02:26

tRNA Activation

22.7K
Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

Activation Energy01:26

Activation Energy

86.5K
Activation energy is the minimum amount of energy necessary for a chemical reaction to move forward. The higher the activation energy, the slower the rate of the reaction. However, adding heat to the reaction will increase the rate, since it causes molecules to move faster and increase the likelihood that molecules will collide. The collision and breaking of bonds represents the uphill phase of a reaction and generates the transition state. The transition state is an unstable high-energy state...

Visual System01:26

Visual System

1.7K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Cardiopulmonary Resuscitation I: Adult

677
Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Aging Research

Background:

  • Cognitive decline is a common aging issue affecting cognitive skills.
  • Existing cognitive training programs lack detailed understanding of their psychological and neural mechanisms.
  • Older adults benefit from interventions, but specific neural changes from art training are underexplored.

Purpose of the Study:

  • To investigate the effects and maintenance of music and visual art training on neuroelectric brain activity in older adults.
  • To compare the neuroplastic changes induced by music and visual art training against a control group.
  • To determine if training-induced neural changes persist long-term.

Main Methods:

  • A partially randomized intervention design was used with 3-month music and visual art training programs.
  • High-density electroencephalography (EEG) measured brain activity during auditory and visual tasks.
  • Neuropsychological assessments were conducted pre-training, post-training, and at a 3-month follow-up.

Main Results:

  • Neither training program significantly improved psychometric measures compared to controls.
  • Both music and visual art training led to persistent enhancements in auditory evoked responses to piano tones.
  • Art training modulated visual processing, but these effects diminished by the 3-month follow-up.
  • Visual art training showed greater changes in visual evoked response (N1 wave) amplitude distribution.
  • Music training demonstrated enhanced inhibitory control in right frontal scalp areas.

Conclusions:

  • Art training (music and visual art) causally induces neuroplastic changes in sensory systems in older adults.
  • Neuroplastic effects on auditory processing were robust and long-lasting (≥3 months).
  • Specific neural changes were observed, with visual art training impacting visual evoked responses and music training impacting inhibitory control.
