Requirements for Human Life

8.5K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Organization of the Brain01:30

Organization of the Brain

937
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 Waves01:23

Brain Waves

1.8K
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:

Metabolic Rate

455
The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence...

Anatomy of the Brain: Major Regions

5.5K
The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...

Summary

Animals sustain energy-demanding brains by reallocating energy, using efficient neural coding, and conserving neural resources during food scarcity. These adaptations ensure brain function and survival despite fluctuating calorie availability.

Area of Science:

  • Comparative physiology
  • Neuroscience
  • Evolutionary biology

Background:

  • The brain is a metabolically expensive organ, requiring significant energy.
  • Animals face challenges in meeting brain energy demands due to unpredictable food availability.

Purpose of the Study:

  • To review and synthesize studies on how animals maintain energy-demanding brains.
  • To identify key energy-saving strategies employed by animals.

Main Methods:

  • Literature review of studies on brain metabolism and energy allocation in animals.
  • Analysis of physiological and neural mechanisms for energy conservation.

Main Results:

  • Animals reallocate energy from peripheral tissues to the brain.
  • Efficient neural coding reduces the brain's operational energy costs.
  • Neural resources are used judiciously during periods of food scarcity.

Conclusions:

  • A diverse array of energy-saving mechanisms enables animals to sustain metabolically costly brains.
  • These adaptations are crucial for survival in environments with variable food resources.
