Brainstem01:19

Brainstem

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...
Organization of the Brain01:30

Organization of the Brain

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

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 Stimulation (TMS).
Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Gut-Brain Axis01:22

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...
Functional Brain Systems: Reticular Formation01:13

Functional Brain Systems: Reticular Formation

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
  • Gerontology
  • Molecular Biology

Background:

  • Target of rapamycin (mTOR) signaling regulates fundamental cellular processes and lifespan across diverse organisms.
  • In mice, chronic rapamycin treatment, which inhibits mTOR, extends lifespan.
  • This suggests potential therapeutic applications of mTOR inhibition in aging and neurodegenerative diseases.

Purpose of the Study:

  • To review the role of mTOR signaling in neuronal function, including feeding, synaptic plasticity, and memory.
  • To explore the mechanisms by which reduced mTOR activity may benefit the aging brain.
  • To examine the implications of mTOR signaling in Alzheimer's disease, Parkinson's disease, and Huntington's disease.

Main Methods:

  • Literature review of studies on mTOR signaling in model organisms and mammalian brains.
  • Analysis of research investigating mTOR's role in neuronal regulation and brain function.
  • Synthesis of findings from studies examining mTOR in age-related neurodegenerative conditions.

Main Results:

  • mTOR signaling is crucial for neuronal functions such as feeding, synaptic plasticity, and memory formation.
  • Reduced mTOR activity shows promise for extending lifespan and improving brain health in aging.
  • Emerging evidence links dysregulated mTOR signaling to Alzheimer's, Parkinson's, and Huntington's diseases.

Conclusions:

  • Modulating mTOR signaling represents a potential therapeutic strategy for age-related cognitive decline and neurodegenerative disorders.
  • Further research into mTOR pathways is warranted to develop effective treatments for brain aging and diseases.
  • Targeting mTOR may offer a novel approach to enhance brain resilience and combat neurodegeneration.
