Understanding Brain Death When someone is brain dead, it means that the brain is no longer working in any capacity and never will again. Other organs, such as the heart, kidneys or liver, can still work for a short time if the breathing machine is left in place, but when brain death is declared, it means the person has died.

Volume of a Human Brain The volume of a human brain, otherwise known as cranial capacity, varies depending on several factors, such as age, environment, and body size. The volume is usually measured in cubic centimeters (cm 3 or cc).Modern humans have cranial capacities from 950 cm 3 to 1800 cm 3, but the average volume of a modern human brain is 1300 cm 3 to 1500 cm 3.Viktoriya Shchupak -- 2001.hile the largest Homo erectus brains were about 1250 ml (2 imperial pints) and modern brains average about 1200–1500 ml in volume, female Neanderthal brains were about 1300 ml and those of males about 1600 ml, extending to 1740 ml in the Amud man.. 1200–1500 cm 3.

IQ and Brain IQ Articles > IQ and Brain. Introduction: The brain is the most complicated, yet sophisticated organ of the human body and allegedly the most prized possession of the race called Homo sapiens. It is the chief control centre of the activities of the body and essentially the seat of all higher thought processes and intelligence.

Human Brain: Facts, Functions & Anatomy The human brain is the command center for the human nervous system. It receives input from the sensory organs and sends output to the muscles. The human brain has the same basic structure as other mammal brains, but is larger in relation to body size than any other brains. 1  The human brain is the largest brain of all vertebrates relative to body size.  It weighs about 3.3 lbs.

- The average adult human brain weighs about 3 pounds – the same weight as the average brain of a dolphin (which is also a very intelligent animal). But there are animals with larger brains that are not considered to be as intelligent as a dolphin. For instance, a sperm whale has a brain that weighs about 17 pounds.

Using Functional Assessments to Determine Mental Capacity in the Person With Dementia Mental Capacity is a functional term that may be defined as: the “mental (or cognitive) ability to understand the nature and effects of one’s acts.” The term capacity is frequently mistaken for competency. Capacity is determined by a physician and not the judiciary.

Number of Neurons in a Human Brain Differences in weight and size of a person's brain does not correlate with differences in mental ability. The adult human brain normally weighs from 1.0 to 1.5 kg (2¼ to 3¼ lbs). The work of the brain is similar to a combination of a computer and a chemical factory.

Why Brain Size Doesnât Correlate With Intelligence In this sense, it’s by downsizing that an individual’s brain is born. Brain size, or the size of brain parts, can be a reasonable indicator of skill, to be sure. In individuals with sensory deprivation other sensory inputs take over the cortical area lying dormant.

What does brain dead exactly mean ? I am so sorry to say this, but brain dead basically means the brain is no longer functioning. The only thing that is working in the body is your heart. There is about 2% chance that he will make it, .........my friends went into a coma and when she was pronounced brain dead the family let her go.

- The literal meaning of anencephaly is no brain.. But the term is not exactly accurate for. describing the condition of anencephalic babies. Such babies have no cerebrum or cerebellum but they do have a brain stem. The brain stem allows them to breathe and allows their hearts to beat. But the babies cannot see, hear, or feel anything.

What is Brain Lateralization? Brain Lateralization is a complex and ongoing process by which differing regions of the brain “take over” the functioning of specific behaviors and cognitive skills.Lateralization literally means that certain functions are located (in part or total) on one side of the brain.unctions related to the left side of the brain include understanding and use of language (listening, reading, speaking and writing), memory for spoken and written language, analysis of information in detail, and motor control of the right side of the body.

Cerebral atrophy Cerebral atrophy is a common feature of many of the diseases that affect the brain.Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.Atrophy can be generalized, which means that all of the brain has shrunk; or it can be focal, affecting only a limited area of the brain and resulting in a decrease of the functions that area of the brain controls.ome degree of cerebral shrinkage occurs naturally with age; after the brain completes growth and attains its maximum mass at around age 25, it gradually loses mass with each decade of life, although the rate of loss is comparatively tiny until the age of 60, when approximately .5 to 1% of brain volume is lost per year.

- ... the processing capacity of the brain has not been reliably determined. But a fair estimate is that the 1.5 kilogram organ has 10^10 neurons, [each] with 10^3 synapses firing an average 10 times per second, which is about 10^14 bits/second.ssuming that most information (in particular, long-term information) is stored in those links, at no more than 10 bits per link, then the absolute maximum capacity of the brain is 25*10^14 bits.

- Brain plasticity— also called neuroplasticity-is an odd term for most people, with the word plastic causing images of Tupperware or Saran Wrap to pop into your head. However, brain plasticity is a common term used by neuroscientists, referring to the brain's ability to change at any age – for better or worse.

What vessel carries deoxygenated blood back to the heart?   Blood passes from the right ventricle to the lungs via the pulmonary artery (the only artery in the body that contains deoxygenated blood veins In the circulatory system … , a vein is a blood vessel that carries blood back toward the heart (as opposed to artery, a blood vessel carrying blood away from the heart).he majority of veins in the body carry low-oxygen blood from the tissues back to the heart; the exceptions being the pulmonary and umbilical veins which both carry oxygenated blood Specifically, the superior and inferior vena cava carry deoxygenated blood back to the heart.

- Because the body and brain work together, a child who is on a physical development program will have greater brain capacity than a child who is not. Physical activity stimulates brain growth Physical activity stimulates brain growth in much the same way that physical exercise causes muscles to develop. child has greater brain capacity when on a physical development program Developing and maintaining the physical form is vital. Make it a pivotal part of your child development program and you will not be sorry.

Buffer solution Buffer capacity, β, is a quantitative measure of the resistance of a buffer solution to pH change on addition of hydroxide ions. It can be defined as follows. where dn is an infinitesimal amount of added base and d(p[H+]) is the resulting infinitesimal change in the cologarithm of the hydrogen ion concentration.

What Is the Memory Capacity of the Human Brain? The human brain consists of about one billion neurons. Each neuron forms about 1,000 connections to other neurons, amounting to more than a trillion connections. If each neuron could only help store a single memory, running out of space would be a problem. You might have only a few gigabytes of storage space, similar to the space in an iPod or a USB flash drive. Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes).
