INTRODUCTION


4/36

Brains Physique Centre of the nervous system in animals.

Controls the central nervous system by way of

the cranial nerves and spinal cord.

Made up of over 100 billion nerve cells.

Uses 20% of the body's oxygen.

Weighs on average three pounds, or 1.5 kg.

Average surface area of the cerebral cortex is

2,500 cm2 or 2.69 sq.ft.

Average spinal cord is 45 cm long in men and

43 cm long in women.

Some Facts

Speed of brain is 10-100 meters per second

Brain weight and size do not mean differencesin mental ability.

Gradual increase in average brain size over the

last centuries (0.5% per decade). About 100 billion neurons in the human brain,

the same number of stars in our galaxy.

Contains around 400 miles of blood vessels.

no sense of pain within the brain itself

Brain generates nearly 25 watts of power,which is enough to light up a light bulb.

Neuron is just 4 microns thick, you could fit30,000 neurons on the head of a pin.

Parts of Brain


7/36

Parts of the brain and their

Functions Frontal Lobe- associated with reasoning,planning, parts of speech, movement,emotions, and problem solving

Parietal Lobe- associated with movement,orientation, recognition, perception of stimuli

Occipital Lobe- associated with visual

processing

Temporal Lobe- associated with perceptionand recognition of auditory stimuli, memory,and speech

Right Vs LeftRight Brain Inventory Left Brain Inventory

Visual, focusing on

images, patterns

Verbal, focusing on words,

symbols, numbers

Intuitive, led by feelings Analytical, led by logic

Process ideassimultaneously

Process ideas sequentially,step by step

Like to know why you're

doing something or why

rules exist (reasons)

Likely to follow rules

without questioning them

Likely to think you're

naturally creative, but need

to apply yourself to develop

your potential

Likely to believe you're not

creative, need to be willing

to try and take risks to

develop your potential

10/36

Cognition

The mental process of knowing, includingaspects such as awareness, perception,reasoning, and judgment.

That which comes to be known, as throughperception, reasoning, or intuition; knowledge.

Cognition throughout life can be broadly

described as an interaction betweenknowledge-driven processes and sensoryprocesses; and between controlled processesand automatic processes.

Blue Brain Project

Started in May 2005

Goal to create a computer simulation of thebrain of mammals including the human brain

In July 2005, EPFL and IBM announced aproject to create a biologically accurate,functional model of the brain using IBM's BlueGene supercomputer.

At the end of 2006, the Blue Brain projecthad created a model of the basic functionalunit of the brain, the neocortical column.

In November, 2007, the Blue Brain project

reached the conclusion of its first Phase

Bionics Introduction to Bionics: Bionics is the

application of biological methods andsystems found in nature to the study anddesign of engineering systems andmodern technology.

Applications of bionics:

Sonar system

Radar system

Medical ultrasound imaging

Artificial Neural Networks

Methods involved in Bionics:1) Mimicking natural methods of manufacture.

2) Imitating mechanisms found in nature.

3) Studying organizational principles from social

behavior of organisms.

Artificial Neural Network (ANN)

What are ANNs?

- ANNs are computational framework How do ANNs work?

- Operate in 2 stages; Training and Recall.

What are the applications of ANNs?

-Analysis of electroencephalogram (EEG)

-Analysis of magnetoencephalogram (MEG)

-Analysis of electromyogram (EMG),

-Analysis of computed tomographic (CT)

-Analysis of and magnetic resonance (MR) brain images


21/36

Cyborg

What are cyborgs?- A cyborg is a cybernetic organism i.ean organism having both artificial andnatural systems.

What are the applications of cyborg?

-In medicine :Restorative or enhanced cyborgs-In Sports:

-In military (cyborg insects

for military purpose)

Blackrock Microsystems

What is Blackrock Microsystems?

Its Purpose

To find Structural evolution of HumanBrain because of increase in technology

How a childs brain react to the technology

-> Developed by National Security

Agency(NSA).

-> Can effectively read ones thoughts and

even control them.

-> Uses supercomputers to monitor millions

of people simultaneously.

-> Can be used to project visual and audio

memory of individuals onto a screen or

monitor.

POINTS COVERED

EFFECTS OF TECHNOLOGY ON HUMAN

MIND

Morally

Spiritually Ethically

EFFECTS OF MOBILES ON HUMAN BRAIN.

EFFECTS OF TECHNOLOGY ON KIDS

MIND.

What can we do?


30/36

EFFECTS OF TECHNOLOGY ON

HUMAN MIND The technological development has, influenced the

current degeneracy of morality, criminality andviolence.

The impact of technology leads too often to a loss of

the sense of the mystery of being self, authenticity andintegrity, the concrete and the existential, truth anddialogue, freedom and lover, humanity

Morality" is a very subjective term to use in a scientificpaper. So yes we make the "choices" of how to

behave by the behavior of the brain

Technology as the ever-present dynamic factoraffecting our daily lives and transforming ourcontemporary civilization could be described as therationally created artificial world of learnableoperational rules, methods, recipes, and skills


31/36

EFFECTS OF MOBILES WHILE

SLEEPING Radiation from mobile phones stimulates brain

activity in the early stages of sleep even afteryou've finished using the phone, an Australian

study shows.

Electromagnetic radiation from mobile phonescan reduce levels of the hormone melatonin,which is connected to the body's sleep-wakecycle.

It is found that exposure to mobile phoneradiation resulted in heightened alpha-waveactivity in the brain.


32/36

EFFECTS OF TECHNOLOGY ON

KIDS MIND A child's brain is most sensitive and most

exposed.

Average kid spends nearly 9 hrs every dayusing this technology.

American Academy of Pediatrics recommends

no TV/videos before age 2.

Possible worsening of attention in childrens


33/36

Children using mobile phones absorb as

much as double the amount of radiation

through their heads as adults.

It is found that more radiation is able to go

pass the ear and into the head since a child's

ear is thinner and the telephone is closer to

the head


34/36

What can we do?

Designate tech-free family time (dinners,evenings, weekends, etc.).

Tech together - kids can teach parents andgrandparents how to text, play games, email,etc.

Look for clues to addiction, tech-driven ADHD,

social withdrawal

Get help - addiction specialists and clinics arenow treating tech addicts


35/36

Conclusion

Where are we exactly reaching

with the contiuely increasing

technology

Life beyond Technology

Spirituality and Humanity

Next Generation What is the aim of life as a

Human?
