Brain Waves01:23

Brain Waves

4.2K
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 Imaging01:14

Brain Imaging

759
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

9.2K
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

3.4K
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.

Summary

Gender dysphoria, or transsexualism, involves a mismatch between biological and experienced gender. Brain changes observed in transgender individuals may result from adapting to new cultural and behavioral contexts, not solely from etiology.

Area of Science:

  • Neuroscience
  • Cultural Neuroscience
  • Psychiatry

Background:

  • Gender dysphoria (transsexualism) is characterized by a discrepancy between biological sex and experienced gender.
  • Neuroimaging studies indicate structural and functional brain alterations in transgender individuals.
  • The causal relationship between these brain changes and gender dysphoria remains unclear.

Purpose of the Study:

  • To review existing neuroimaging studies on transgender individuals.
  • To explore the potential role of the culture-behavior-brain (CBB) loop model in understanding brain changes.
  • To investigate whether observed brain alterations are etiological or consequential to lifestyle and cultural shifts.

Main Methods:

  • Literature review of neuroimaging studies concerning transgender populations.
  • Application of the culture-behavior-brain (CBB) loop model to analyze findings.
  • Discussion of the interplay between culture, behavior, and brain plasticity.

Main Results:

  • Transgender individuals undergo changes in lifestyle, beliefs, and cultural practices.
  • These cultural and behavioral shifts are closely intertwined with brain function and structure.
  • The brain demonstrates adaptability, altering its structure and function in response to new cultural and conceptual environments.

Conclusions:

  • Observed brain changes in transgender individuals may be an adaptive response to their evolving culture and behaviors.
  • The CBB loop model provides a framework for understanding how social and cultural factors influence neurobiology.
  • Further research is needed to fully elucidate the complex relationship between gender identity, culture, and brain plasticity.
