No computer works as efficiently as the human brain - so much so that building an artificial brain is the
goal of many scientists, said researchers, building an artificial sensory processing system that exhibits
This innovative device called neuromorphic chip imitates the brain's information processing abilities
Few pursue the Zurich researchers' approach to develop electronic circuits that are comparable to a real brain in
terms of size, speed, and energy consumption.
"Our goal is to emulate the properties of biological neurons and synapses directly on microchips," explains Giacomo
Indiveri, a professor at the Institute of Neuroinformatics (INI), of the University of Zurich and ETH Zurich.
The major challenge was to configure networks made of artificial, i.e. neuromorphic, neurons in such a way that they
can perform particular tasks, which the researchers have now succeeded in doing:
They developed a neuromorphic system that can carry out complex sensorimotor tasks in real time.
They demonstrate a task that requires a short-term memory and context-dependent decision-making - typical traits that
are necessary for cognitive tests.
In doing so, the INI team combined neuromorphic neurons into networks that implemented neural processing modules
equivalent to so-called "finite-state machines" - a mathematical concept to describe logical processes or computer programs.
Behavior can be formulated as a "finite-state machine" and thus transferred to the neuromorphic hardware in an
"The network connectivity patterns closely resemble structures that are also found in mammalian brains," says Indiveri.
The scientists thus demonstrate for the first time how a real-time hardware neural-processing system where the user
dictates the behavior can be constructed.
"Thanks to our method, neuromorphic chips can be configured for a large class of behavior modes. Our results are pivotal
for the development of new brain-inspired technologies," Indiveri sums up.
One application, for instance, might be to combine the chips with sensory neuromorphic components, such as an artificial
cochlea or retina, to create complex cognitive systems that interact with their surroundings in real time.
Do We Live In A Computer Simulation Created By An Advanced Alien Civilization?
The captivating idea that we might be living in 3 dimensional holographic simulation has been put forward by various scientists.
We will explore this mind-boggling idea further and examine some intriguing questions.
If we suspect that we are programmed beings living inside a simulation is there any way for us to find out if this is true?
Is it possible to change the outcome of this virtual game?
Death Is Just An Illusion:
We Continue To Live In A Parallel Universe
For as long as anyone can remember philosophers, scientists and religious men have pondered what happens after death.
Is there life after death, or do we just vanish into the great unknown?
There is also a possibility there is no such thing as what we usually define as death.
A new scientific theory suggests that death is not the terminal event we think.
