Hello.
Welcome back.
In this lesson we shall give a quick summary of the functional description of biological neuron.
The foundational units of the human brain is the neuron a tiny piece of the brain about the size of
a grain of rice contains over 10000 neurons each of which forms an average of six thousand connections
with other neurons.
It is this massive biological network that enables us to to experience the world around us at its core.
The neuron is optimized to receive information from other neurons.
Process this information in a unique way and send it to resort to other cells are shown in this image
over here that no one receives.
It's uh it's inputs a long antenna like structures called Bender writes each of these incoming connections
is dynamically strengthened or weakened based on how often it is used.
This is how we learn new stuff and it's the strength of each connection determines the contribution
of the inputs to the neurons output.
I repeat is the strength of each connection that determines the contribution of the input to the neurons
outputs after boom weighted by the strength of the respective connections the inputs are summed together
in these cell body.
This sum is then transformed into a new signal that is propagated along the cells axon and sent off
to other neurons.
I'm just explaining this and wanting to think about similarities between this and the one that we are.
We are designing so now that the biological neuron is out of the way.
Let's go back to the artificial neurons.
