Cerebrospinal Fluid01:21

Cerebrospinal Fluid

2.8K
Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....

Anatomy of the Brain: Ventricles

4.8K
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.

Neurulation01:30

Neurulation

42.3K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Brainstem01:19

Brainstem

2.7K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

Area of Science:

  • Neuroscience
  • Physiology
  • Developmental Biology

Background:

  • The choroid plexus, a brain barrier, has been studied less than the blood-brain barrier despite its long history.
  • Historically, research focused on cerebrospinal fluid (CSF) secretion and blood flow control.
  • Recent research emphasizes the choroid plexus's role in brain development and function via CSF-borne molecules.

Purpose of the Study:

  • To review unanswered questions in choroid plexus research, including CSF secretion and blood flow.
  • To examine recent findings on the choroid plexus's specific contributions to brain development and function.
  • To explore the choroid plexus's role in neurogenesis, hormonal regulation, circadian rhythms, and sleep.

Main Methods:

  • Literature review of historical and recent (past 10 years) choroid plexus research.
  • Analysis of studies focusing on CSF composition and stability.
  • Examination of research on choroid plexus-generated factors and their impact on brain growth.

Main Results:

  • The choroid plexus is critical for maintaining the brain's internal environment.
  • CSF produced by the choroid plexus is essential for neurogenesis and brain development.
  • Emerging research links choroid plexus function to hormonal influences, circadian rhythms, and sleep.

Conclusions:

  • The choroid plexus plays a vital role throughout life, particularly in brain development and function.
  • Future research directions include therapeutic delivery via CSF and understanding maternal drug exposure impacts.
  • Further investigation into choroid plexus function is crucial for advancing neuroscience and treating neurological disorders.
