Lesson 4: Sensory processing and the brainSensory processing and the brain
Review your understanding of sensory processing and the brain in this free article aligned to NGSS standards.
Key points:
- The nervous system helps humans and other animals sense and respond to their environments.
- Sensory receptors are cells or cell parts that detect signals from the environment. These signals are called stimuli.
- Some sensory receptors detect mechanical stimuli. These include the receptors involved with our sense of touch.
- Other sensory receptors detect chemical stimuli. These include the receptors involved with our senses of taste and smell.
- Others detect electromagnetic stimuli. These include the receptors involved with our sense of sight.
- Information from sensory receptors is transmitted, or passed along, nerve cells to the brain.
- The brain processes, or organizes, information from different sensory receptors. The brain can then trigger a response or store the information as a memory.

why do we need to blink?(35 votes)
It helps your eyes stay moist, and keeps some grime out of them.(61 votes)

so what about the people that cant feel pain how does that work can they just not feel anything or is it just like a wired sensation or something and why do we feel pain what sense is that because it didn't explain that in the video?(18 votes)
Pain is its own sense. The human body has pain receptors all over. Pain receptors send a signal to the brain through the neurons that tell the brain something is wrong. That message is what we perceive as pain. Some individuals have a different genetic trait that results in a different sensation of pain: it simply doesn't hurt. They feel something, but not the unpleasantries that everyone else feels.(19 votes)
What happens if we don’t blink? Do we die?(5 votes)
Well, it can make you completely blind after a period of time, but there are other side effects before blindness that could kill you (ex. swelling of lymph nodes, which in turn makes your immune system not work properly and parasites which some species may kill you). If you are lucky however, you can survive all of the symptoms and instead get total blindness (which is also very disastrous so don't try it)(23 votes)
so what happend to the blind poeple?

if someone is donating a kidney will they have to cut open their stomatch?
is it possible to donate a brain?(6 votes)
When someone donates a kidney, the process typically involves a surgical procedure called a nephrectomy. However, the surgeon does not need to cut open the stomach. Instead, they make small incisions in the side or abdomen to remove the kidney. This is known as laparoscopic surgery, which is minimally invasive and offers several benefits such as quicker recovery and minimal scarring.
As for donating a brain, currently, it is not possible to donate a brain while the donor is alive. The brain is a highly complex and vital organ that cannot be transplanted from one person to another. Brain activity and consciousness are intricately linked, making it challenging to transfer such functions between individuals. At present, brain donation for scientific research purposes typically occurs after a person's passing to study specific conditions or diseases.(21 votes)

If your skin got ripped off would the nervous cells there die? Would you still feel pain if you pinch the scar left after? Or would the nervous system heal itself after?!(7 votes)- If your skin were to be ripped off, the cells there would not die, but no, pinching the scar would not hurt just because you have been wounded there before. Your body would heal itself over time.
( but you should definitely go to the hospital to get some medical attention if this were to happen )(8 votes)
Why is stimuli related to sight called electromagnetic stimuli??(4 votes)
What is the stimulus for the sense of sight?
Image result for Why is stimuli related to sight called electromagnetic stimuli??
Visual (seeing) Sight is processed through the 'Visual' sense. Visual stimuli is picked up by visual receptors located in the eye. Visual receptors are stimulated by light, colour and movement. I hope this answers your question.(6 votes)
the human body has lots of different cool stuff it detects senses like if we have a antena(7 votes)- You are quite right. Ants and other species use there antennae to sense smells in the air, tap the ground to alert the rest of the colony, directly tap other ants to communicate, and sense there surroundings in the dark of there nest. Ants need all of these skills from there antennae because they do not have hearing and a nose.(2 votes)
