Virtual Reality System for Small Animals Based on Raspberry Pi
Virtual Reality System for Small Animals Based on Raspberry Pi. The Raspberry Pi Virtual Reality system (PiVR) is a versatile tool for presenting virtual reality environments to small, freely moving animals (such as flies and fish larvae), according to a study published today (July 14, 2020) in the open-access journal PLOS Biology by David Tadres and Matthieu Louis of the University of California, Santa Barbara. The use of PiVR, together with techniques like optogenetics, will facilitate the mapping and characterization of neural circuits involved in behavior.
PiVR consists of a behavioral arena, a camera, a Raspberry Pi microcomputer, an LED controller, and a touchscreen. This system can implement a feedback loop between real-time behavioral tracking and delivery of a stimulus. PiVR is a versatile, customizable system that costs less than $500, takes less than six hours to build (using a 3D printer), and was designed to be accessible to a wide range of neuroscience researchers.

In the new study, Tadres and Louis used their PiVR system to present virtual realities to small, freely moving animals during optogenetic experiments. Optogenetics is a technique that enables researchers to use light to control the activity of neurons in living animals, allowing them to examine causal relationships between the activity of genetically-labeled neurons and specific behaviors.
As a proof-of-concept, Tadres and Louis used PiVR to study sensory navigation in response to gradients of chemicals and light in a range of animals. They showed how fruit fly larvae change their movements in response to real and virtual odor gradients. They then demonstrated how adult flies adapt their speed of movement to avoid locations associated with bitter tastes evoked by optogenetic activation of their bitter-sensing neurons. In addition, they showed that zebrafish larvae modify their turning maneuvers in response to changes in the intensity of light mimicking spatial gradients. According to the authors, PiVR represents a low-barrier technology that should empower many labs to characterize animal behavior and study the functions of neural circuits.

Q.Are EasyShiksha's internship certificates recognized by universities and employers?
Yes, EasyShiksha's internship certificates are recognized and valued by universities, colleges, and employers worldwide. They serve as a testament to your skills, knowledge, and experience gained through our internship programs.
Q.Is the download of certificates free or paid?
While access to internships and all courses on EasyShiksha is free for users lifetime, there is a nominal operational cost associated with downloading certificates. This fee covers the administrative expenses involved in processing and issuing the certificates.
Q.When can I start the course?
Anyone can choose a preferred course and start immediately without any delay.
Q.What are the course and session timings?
As this is a purely online course program, you can choose to learn at any time of the day and for as much time as you want. Though we follow a well-established structure and schedule, we recommend a routine for you as well. But it finally depends on you, as you have to learn.
Q.What will happen when my course is over?
If you have completed the course, you would be able to have lifetime access to it for future reference too.
Q.Can I download the notes and study material?
Yes, you can access and download the content of the course for the duration. And even have lifetime access to it for any further reference.
Q. What software/tools would be needed for the course and how can I get them?
All the software/tools that you need for the course would be shared with you during the training as and when you need them.
I’m unable to make a payment. What to do now?
You can try to make the payment through a different card or account (maybe a friend or family). If the problem persists, email us at info@easyshiksha.com
Q. Do I get the certificate in a hard copy?
No, only a soft copy of the certificate will be awarded, which can be downloaded and printed, if required.
Q. The payment got deducted, but the updated transaction status is showing “failed”. What to do now?
Due to some technical faults, this can happen. In such a case the amount deducted will be transferred to the bank account in the next 7-10 working days. Normally the bank takes this much time to credit the amount back into your account.
Q. The payment was successful but it still shows ‘Buy Now’ or not showing any videos on my dashboard? What should I do?
At times, there may be a slight delay in your payment reflecting on your EasyShiksha dashboard. However, if the problem is taking longer than 30 minutes, please let us know by writing to us at info@easyshiksha.com from your registered email id, and attach the screenshot of the payment receipt or transaction history. Soon after verification from the backend, we will update the payment status.
Q. What is the refund policy?
If you have enrolled, and are facing any technical problem then you can request a refund. But once the certificate has been generated, we shall not refund that..
Q.Can I just enrol in a single course?
Yes! You surely can. To begin this, just click the course of your interest and fill in the details to enrol. You are ready to learn, once the payment is made. For the same, you earn a certificate too.

“More than ever,” the authors note, “neuroscience is technology-driven. In recent years, we have witnessed a boom in the use of closed-loop tracking and optogenetics to create virtual sensory realities. Integrating new interdisciplinary methodology in the lab can be daunting. With PiVR, our goal has been to make virtual reality paradigms accessible to everyone, from professional scientists to high-school students. PiVR should help democratize cutting-edge technology to study behavior and brain functions.”
