Brain Waves01:23

Brain Waves

3.9K
Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:

Organization of the Brain01:30

Organization of the Brain

2.4K
The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Brain Imaging01:14

Brain Imaging

681
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

8.4K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Neurons as Communicators of the Brain

3.0K
Neurons, the fundamental units of the brain and nervous system, function as the primary transmitters of information throughout the body. Their ability to communicate through electrical and chemical signals is vital for every bodily function, from regulating the heartbeat to processing complex thoughts. Each neuron has three main components: the cell body (soma), dendrites, and an axon, each specialized to facilitate swift and efficient neural communication.

The cell body, also known...

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Anesthesiology

Background:

  • Anesthetic agents commonly target N-Methyl-D-Aspartate (NMDA) and gamma-aminobutyric acid A (GABAA) receptors.
  • This mechanism suggests a biological plausibility for anesthesia affecting neurodevelopment.
  • Animal studies indicate lasting neurological changes following anesthetic exposure.

Purpose of the Study:

  • To review current evidence on the effects of anesthesia on the developing brain.
  • To identify potential long-term outcomes associated with pediatric anesthesia.
  • To inform strategies for minimizing harm in pediatric patients.

Main Methods:

  • Literature review of existing studies on pediatric anesthesia and neurodevelopment.
  • Analysis of animal and emerging human research.
  • Synthesis of data to assess the impact on the developing brain.

Main Results:

  • Animal studies suggest significant neurological changes.
  • Human studies are ongoing with conflicting data.
  • The direct applicability of animal findings to humans remains uncertain.

Conclusions:

  • Further research is needed to clarify the risks of anesthesia in pediatric neurodevelopment.
  • Evidence synthesis is crucial for developing safer anesthetic practices.
  • Minimizing exposure during critical developmental periods is a key consideration.
