What Does the Lab Do?[edit]

Our research seeks to elucidate the neural underpinnings of emotion. Our progress ultimately relies upon a symbiosis of psychological theory and neuroscience methods.

Lab Goals[edit]

  • To characterize the anatomical trajectories of affective circuits in the brain.
  • To characterize how psychopharmacological (drug) manipulations modulate affective experience.
  • To understand how the function of these affective circuits is damaged in affective disorders and addiction.
  • To understand how psycho- and pharmaco- therapies can normalize damaged affective circuits.
  • To understand, by reducing the problem to its individual components, how affective circuitry modulates decision-making and economic behavior
  • To innovate and create new technologies and techniques for tracking affective dynamics in the brain.

Basically, our current focus is on how emotion influences decisions (including financial) and mental health symptoms. This proactive view differs from the traditional view of emotion, which emphasizes emotion's reactive nature. The phrase "anticipatory affect" refers to valenced and aroused emotions that occur when people are anticipating an uncertain outcome. We think these these states are best situated to influence what we do next.

Overview of Research Process[edit]

Generally speaking, research in the lab follows this trajectory (a.k.a., the "pipeline"):

BRAINSTORM → IRB PROPOSAL → PILOT → TWEAK → BEHAVIORAL STUDY → FMRI STUDY → PROCESSING → ANALYSIS → PUBLICATION → FAME AND FORTUNE

Each of these steps appears later in greater detail, but first, an overview of key regions and their functions.

How do I get started?[edit]

Undergraduates[edit]

  • Take some serious time over the course of a week or two to read Scott Huettel’s Functional Magnetic Resonance Imaging textbook. Aside from some unavoidably gnarly physics, it’s well-written and accessible to readers, even those with very little background in psychology or biology. Don’t worry about retaining everything; a good once-through will make what we do here in the lab a lot more understandable.
  • Read through this manual.
  • Spend some quality time with the lab’s Unix/Linux books. This will save you time later on.
  • Familiarize yourself with the lab’s publications. They’re available on the lab homepage (www-psych.stanford.edu/~span/).
  • Talk to the lab coordinator to see if there’s anything else you need to do.

Graduate Students[edit]

  • Figure out what your SUId name and SUId number are.
  • Check to see if your Stanford email account is working; you can do this at webmail.stanford.edu.
  • Go to the ID office to get an ID card.
  • Talk to Harry Bahlman, the building facilities manager/guru, about obtaining a key to your office and swipe card access to the building. Harry is located on the LL (lower level) in room 01-420. You can also email him at harry@psych.stanford.edu.
  • Bring computer to Peter to get it set up for wireless. Also for a psych email address.
  • Contact Anne Sawyer to sign up for a scanner safety training course (amsawyer@stanford.edu); it’s required before you can enter the magnet room and it’s only held once or twice a month.
  • To run human subjects, you need to complete the university’s human subjects use course, which is run by CITI.
  • You’ll also want to read about the rules and regulations particular to Stanford in the Research Policy Handbook (http://www.stanford.edu/dept/DoR/rph/Chpt7.html/), and on the Stanford Human Subjects Research page (http://humansubjects.stanford.edu/)
  • Make sure you’re comfortable with EPrime (a popular psychology experiment package that allows you to create experiment modules on the computer -- we use this for the stimuli subjects see while in the scanner) and the Linux environment.
  • If you’re not already an fMRI guru, take some serious time over the course of a week or two to read Scott Huettel’s Functional Magnetic Resonance Imaging textbook. Aside from some unavoidably gnarly physics, it’s well-written and accessible to most readers, even those with very little background in psychology or biology. Don’t worry about retaining everything; a good once-through will make what we do here in the lab a lot more understandable.

RAs[edit]

  • Contact Anne Sawyer (amsawyer@stanford.edu) to sign up for the next available scanner safety course. Be sure to tell her your name, your lab association, and that you will be in the lab for more than six months. The Lucas Center does not train people who will not be using the magnet for more than half a year. You cannot enter the magnet room without this training.
  • If you’re not already an fMRI guru, take some serious time over the course of a week or two to read Scott Huettel’s Functional Magnetic Resonance Imaging textbook. Aside from some unavoidably gnarly physics, it’s well-written and accessible to most readers, even those with very little background in psychology or biology. Don’t worry about retaining everything; a good once-through will make what we do here in the lab a lot more understandable.
  • Talk to HR to make sure all your paperwork is in order. Bring a cancelled check to sign up for direct deposit. Also bring your passport and contact information for your emergency contact sheet (phone numbers and addresses).
  • Make an appointment with the department HR contact to go over Kronos (this is currently Bhavna Raval, braval@stanford.edu)
  • Figure out what your SUId name and SUId number are.
  • Check to see if your Stanford email account is working; you can do this at webmail.stanford.edu.
  • Go to the ID office to get an ID card. [insert map]
  • Talk to Harry Bahlman, the building facilities manager/guru, about obtaining a key to your office and swipe card access to the building. Harry is located on the LL (lower level) in room 01-420. You can also email him at harry@psych.stanford.edu.
  • If you’re an RA, log on to axess.stanford.edu to enroll in the Stanford 101 course (Training tab → Search Catalog → “Stanford 101”). It’s required of all employees, and it’s where you receive all your benefits information. Be sure to do this within 30 days of your first day on the job – if you don’t, you’ll be automatically enrolled in default benefits plans, will miss others, and won’t be able to change anything till the next “open enrollment,” which only occurs once a year.
  • To run human subjects, you need to complete the university’s human subjects use course, which is run by CITI.
  • You’ll also want to read about the rules and regulations particular to Stanford in the Research Policy Handbook (http://www.stanford.edu/dept/DoR/rph/Chpt7.html/), and on the Stanford Human Subjects Research page (http://humansubjects.stanford.edu/)

What's where?[edit]

SPAN lab is small in physical size and big on ideas. The lab space can be broken into four areas: room 465 (the main SPAN lab room), room 467 (the SPAN experiment room), the Lucas Center (this is where we scan, it’s located at the Med School), and grad student offices.

Locations and Resources[edit]

Room 465: The main lab room
This room houses the printer, the MacBook (this computer is called ‘insula’), a Linux workstation (‘dmthal’), an old iBook, the file cabinets, and some reference materials on the bookshelf.
Lab Manager
Use this resource sparingly to answer any question. Bother him/her more than and/or prior to bothering Rm 470 (Prof. Knutson).
Spanlab Printer
You can print here from any of the Mac or Linux computers. The name of the printer is spanlab (ip address spanlab.Stanford.edu). That should automatically come up on a Mac, but for Windows configuration, you may need to dig up the printer CD and find just the right folder for the drivers (this may be trial-and-error, sorry).
MacBook (‘insula’ –knutson@insula.stanford.edu)
Insula is the main station in the lab for using Photoshop CS3, Excel, Word, PowerPoint, Deltagraph, and SPSS. It also works as a terminal to connect to the Linux stations remotely (use the X11 utility and type “ssh –Y span@dmthal.stanford.edu” in the terminal window to connect to dmthal; importantly use “-Y” on this computer). To find data for a study (e.g. activation timecourse spreadsheets) click on the “Macintosh HD” icon on the desktop and go to the folder /Users/Knutson/data. There is a folder for every study where you will find spreadsheets of data and whatnot.
Note that all logins will be span@insertcomputername except for insula, which is Knutson@.
dmthal
A fast Linux workstation (from summer 2005). This computer replaced mpfc as the primary computer for data processing and storage. It contains a dual-core processor and 500GB+ of storage. New studies will go on this computer (until it is retired).
Filing cabinet:
1st drawer – pens, pins, other supplies.
2nd drawer – copies of consent forms and payment sheets.
3rd drawer – subject folders (one folder for every subject scanned, containing questionnaires and consent).
4th drawer – file folders.
Bookshelf
Software CDs, Software manuals, other books deemed useful (e.g. UNIX for dummies). Also, CDs for programs and drivers. The E-Prime manuals and CD should be on the bookshelf in this room (note in 10/2006 these manuals disappeared! – prize for recovery)
iBook: the bookshelf usually holds a stripped down MacOS X laptop. Use it for SPSS, Deltagraph, or for connecting to the Linux computers. (it is networked wirelessly so you don’t need to plug it in anywhere)
Room 467
467 is an auxiliary lab room used for behavioral experiments and task design in E-Prime. There is a windows desktop that you can use with the serial button box. There are also two laptops, a lenovo thinkpad running windows for e-prime and a macbook that can be used in windows mode for e-prime or in regular mode for psychtoolbox based experiments. These laptops can be used with the usb button box.
Room 470
Brian’s office. This is where the intellectual magic happens. (contains span@mpfc computer)
Rooms 469, 478, and 480
Grad student and RA offices. More magic. Room 480 holds a Linux workstation called amygdala that is for general lab use. (478 currently holds span@nac (with J. Cooper))
Lucas Center
We scan with the 1.5 Tesla magnet and the 3 Tesla magnet, but by and large we use the 1.5T. If you’re scanning, you should have someone show you where everything is. Make sure that one of you has a swipe card with which to get in.
Keep in mind that you’ll need to bring consent forms, questionnaires, and payment forms. If you ever forget to bring anything, there may be extras in the knutson drawer in the prep room outside the magnet room (1.5T only). If you take extras try to replenish the supply the next chance you get. Also, if the bite bar goop is going low, check with the lab manager or check on top of the brown bookcase in rm 465. The windows computer in the first room (closest to the lobby reception area) can connect to the scanner computer and is used to grab data and transfer it to the spanlab computers (use SecureFX to connect). Follow instructions on the wall next to the computer to grab data files from the scanner computer (use get11 for structurals, SecureFX to lcmr1 for functionals at the 1.5T – also see the scanning protocol in a later section of this manual).
Other:
dmthal and amygdala (the main Linux stations), mpfc, and nacc (with older data) can be accessed remotely from any computer.
Kitchen Facilities
We share kitchen space with the rest of the fourth floor. As you exit the lab coordinator’s office, turn left, and left again. Walk past the water fountain, then turn right. You’ll find a small kitchen space (communal fridge, microwave, sink) and a table. Please label your food and don’t let it become the source of a CDC level 3 quarantine.
