Brain Waves01:23

Brain Waves

4.1K
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

2.7K
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 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: Ventricles

8.9K
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 Brain01:22

Neurons as Communicators of the Brain

3.2K
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.

Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Complex Systems

Background:

  • Traditional neuroscience models brain activity in 3 spatial + time dimensions.
  • Recent advancements in big data and computational tools challenge this view.
  • Emerging research suggests brain activity can be analyzed in higher-dimensional phase spaces.

Purpose of the Study:

  • To review the concept of higher dimensions in brain activity analysis.
  • To explore whether these dimensions represent methodological conveniences or genuine functional/anatomical relationships.
  • To discuss the implications for understanding cognition and neurological diseases.

Main Methods:

  • Review of existing literature on multidimensional analysis of neural data.
  • Description of methods for extracting hidden multidimensional information from neurodata.
  • Theoretical discussion on information processing and dimensionality.

Main Results:

  • Higher dimensions in brain activity may reflect true functional or anatomical relationships.
  • The human mind appears to dilute environmental inputs, not concentrate them.
  • A principle of "higher dimension, greater information" is proposed.

Conclusions:

  • Multidimensional analysis offers deeper insights into brain function beyond traditional models.
  • Understanding dimensionality is crucial for explaining mental activities.
  • Dimensionality reduction may underlie certain human diseases.
