3. Introduction
Brain chips is often referred to as neural
implants or technological devices that
connects directly to a biological ly
subjected brain.
When we are entering into this topic,
the works of the physiologist JOSE
DELGADO need to be mentioned.
6. Neural Network
• Neural networks are loosely modeled
on the networks of neurons.
• They are especially effective at
recognizing patterns, classifying data,
and processing noisy signals…
7. HOW BCI WORKS
The nerve cells in our brain are
receiving ,interpreting and responding
to the bombardment of information.
These produce impulses as some
electric signals.
These electric signals are received by
this chip and this chip convert these
signals to the human understandable
language by means of a computer.

causes a different bunch of sensory neurons in our
eyes to light up in a flurry of electrical activity,
conveying the text and images to the brain, while
as many as 100 billion neurons network the
electrical signals1, forming our thoughts and
directing our actions.
Neurons conduct information as electrical
impulses as internal fluctuations in voltage.
Normally they do this to communicate amongst
themselves, however any electrical device can
potentially 'speak' the language of a neuron if only
it could listen closely enough. It is by listening
closely that brain-computer interface technology is
able to interpret the languages of our neurons.

11. The neurosurgeon begins by cutting through the scalp to
reach the skull. Then, small holes (burr holes) are drilled into
the exposed skull with an instrument called a perforator. To
create a removable bone flap, a high speed drill named a
craniotomy is used to cut through the skull, moving from one
burr hole to the next. This step allows for the removal of
small disc of bone. With the use of a scalpel, the
neurosurgeon can then cut through the protective
membranes of the brain (dura, arachnoid, pia) to reach the
primary motor cortex. With the aid of a small pneumatic
inserter and a plan for placement, the surgeon can place the
sensor. This sensor – a tiny silicon chip about the size of a
baby aspirin contains 100 electrodes, each 1 millimeter long -
- is then pressed onto the surface of the cortex. The patient’s
skull is closed through the replacement of the piece of
excised bone with titanium screws, the muscle and skin are
sutured and a drain is placed inside the brain to remove
excess blood from the surgery.
13. Guided rats controlled through implants in their
brains could one day be used to search for
landmines or buried victims of earthquakes,
scientists say.An extraordinary experiment has
seen researchers steering five rodents - so-called
ratbots - through an obstacle course by remote
control. Electrodes were implanted into areas of
the rats' brains responsible for sensing reward,
as well as those that process signals from the
whiskers.
The commands and rewards were transmitted
by radio from a laptop computer to a backpack
receiver strapped to each rodent.

15. Achievements In This Field
“pace makers”
They are implantable neurons that
would perform the function of a part
of heart that has been damaged by
stroke or epilepsy...
16. Benefits of Brain Chips
• It will increase the dynamic ranging of
senses.
• Giving light to blind and giving paralyzed
patients full mental control of limbs.
• Rescue missions(remote controlled rat).
• The Chips take away one's free will. It
enables a person to make a better
choice not to take drugs at all.
17. Limitations
• Cost
• Losing Identity in some cases.
• safety(non toxic substance)
• Risk for surgeons.
• Easy to hack the brain
18. Conclusion
• Brain implants enhance capability of
human organs and senses.
• It has a significant role to play in
future genetic engineering fields and
neuroscience.
he is the man, that gave technology to its present form.
The goal of brain chip is to develop a fast and reliable connection between the brain of a severely disabled person and a computer
Brain chips are made with a view to enhance the memory of human beings, to help paralyzed patient
The brain gate device can provide a mode of communication through the translation of thought into direct computer control.
It is the most complicated area of research as they works on neural networks.
They are used to perform complex tasks.

delgado showed that stimulation of the motor cortex could evoke specific physical reactions, such as movement of the limbs stimulation ,By stimulating different regions of the limbic system, which regulates emotion, fear , anger , love, amusement, garrulousness and other reactions, some of them startling in their intensity.
A pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses low-energy electrical pulses to prompt the heart to beat at a normal rate.
Pacemakers are used to treat arrhythmias. Arrhythmias are problems with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.
The linkage of smaller, lighter, and more powerful computer systems with radio technologies will enable users to access information and communicate anywhere or anytime. Through miniaturization of components, systems have been generated that are wearable and nearly invisible, so that individuals, supported by a personal information structure, can move about and interact freely, as well as, through networking, share experiences with others. The wearable computer project envisions users accessing the Remembrance Agent of a large communally based data source.
