Hello.

2
00:00:01,260 --> 00:00:02,460
Welcome back.

3
00:00:02,490 --> 00:00:09,370
In this lesson we shall give a quick summary of the functional description of biological neuron.

4
00:00:09,390 --> 00:00:15,670
The foundational units of the human brain is the neuron a tiny piece of the brain about the size of

5
00:00:15,670 --> 00:00:24,030
a grain of rice contains over 10000 neurons each of which forms an average of six thousand connections

6
00:00:24,030 --> 00:00:27,140
with other neurons.

7
00:00:27,210 --> 00:00:35,920
It is this massive biological network that enables us to to experience the world around us at its core.

8
00:00:35,940 --> 00:00:40,610
The neuron is optimized to receive information from other neurons.

9
00:00:40,680 --> 00:00:48,180
Process this information in a unique way and send it to resort to other cells are shown in this image

10
00:00:48,270 --> 00:00:50,910
over here that no one receives.

11
00:00:50,910 --> 00:01:00,810
It's uh it's inputs a long antenna like structures called Bender writes each of these incoming connections

12
00:01:01,220 --> 00:01:07,140
is dynamically strengthened or weakened based on how often it is used.

13
00:01:07,170 --> 00:01:17,940
This is how we learn new stuff and it's the strength of each connection determines the contribution

14
00:01:18,000 --> 00:01:20,750
of the inputs to the neurons output.

15
00:01:20,790 --> 00:01:31,670
I repeat is the strength of each connection that determines the contribution of the input to the neurons

16
00:01:31,760 --> 00:01:41,060
outputs after boom weighted by the strength of the respective connections the inputs are summed together

17
00:01:41,150 --> 00:01:42,920
in these cell body.

18
00:01:42,920 --> 00:01:51,680
This sum is then transformed into a new signal that is propagated along the cells axon and sent off

19
00:01:51,680 --> 00:01:53,510
to other neurons.

20
00:01:53,540 --> 00:01:59,390
I'm just explaining this and wanting to think about similarities between this and the one that we are.

21
00:01:59,930 --> 00:02:05,300
We are designing so now that the biological neuron is out of the way.

22
00:02:05,360 --> 00:02:08,030
Let's go back to the artificial neurons.
