Brain Imaging01:14

Brain Imaging

747
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...

Functional Brain Systems: Limbic System01:15

Functional Brain Systems: Limbic System

7.4K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Higher Mental Functions of the Brain: Language

3.9K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Compounds Essential to Human Function

10.3K
The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

Higher Mental Functions of Brain: Learning and Memory01:26

Higher Mental Functions of Brain: Learning and Memory

2.1K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Functional Brain Systems: Reticular Formation01:13

Functional Brain Systems: Reticular Formation

5.0K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

Area of Science:

  • Neuroscience
  • Psychopharmacology
  • Neuroimaging

Background:

  • Oxytocin (OT) is known for prosocial effects, but other neuropeptides' brain impacts are less studied.
  • Functional magnetic resonance imaging (fMRI) is a key tool for investigating neuropeptide effects on neural responses.

Purpose of the Study:

  • To meta-analyze the brain effects of arginine-vasopressin using coordinate-based activation likelihood estimation.
  • To review existing fMRI data on other neuropeptides and their therapeutic potential in mental disorders.

Main Methods:

  • Coordinate-based activation likelihood estimation (ALE) meta-analysis for arginine-vasopressin.
  • Review of pharmacological and genetic fMRI studies on various neuropeptides.
  • Examination of studies involving external neuropeptide administration in patients.

Main Results:

  • Neuropeptides, including arginine-vasopressin and oxytocin (OT), modulate activity in limbic and cortical brain areas.
  • Evidence suggests neuropeptides can influence neural responses relevant to mental health conditions.

Conclusions:

  • Neuropeptides show promise for therapeutic drug development targeting mental disorders like autism and schizophrenia.
  • Further systematic research on a broad range of neuropeptides is crucial for understanding brain function and disease mechanisms.
