Spring Semester 2024-2025

The Cognition and Neural Systems (CNS) Journal Club (nee' BCS Journal Club), also known as PSYCH 6271-101, meets on Tuesdays from 11:40 to 1:15 pm in 205 Uris Hall (across from the elevators). 

Papers and notes from previous semesters can be found in the CNS (BCS) meeting archive.

Presentations in the CNS JC are intended to "show us what you are interested in"; i.e., present work within your subfield that illustrates why it is interesting and broadly applicable.  It is less important to choose papers that you think will be close to every attendees' heart than it is to choose papers that are blisteringly important or interesting or controversial in your own subfield, and explain/share this with the group.  It's good for all of us.  The corollary is that journal club members attend regularly, and don't decide whether to attend in a given week based on what is being presented.  

Presenting your own work is always welcome, in whatever manner you like.


To add yourself to the mailing list, send a plain-text email to bcs-L-request@cornell.edu  (BCS is the historical name of the journal club) with the subject line of the message saying simply join, and the body of the message blank/empty.  Sending the message with a subject line of leave instead will unsubscribe you from the list. See Cornell's Lyris HowTo page for further details.

You can enroll in the CNS Journal Club for credit (1 CR, S/U) as a Topics in Biopsychology seminar: PSYCH 6271-101. The course requires that you present at least once during the semester and participate actively overall. You are welcome to attend without enrolling, of course, but we do appreciate you enrolling if you plan to attend the whole semester and to present.

Please contact Thomas Cleland or David Smith with any questions.

  • Hyon R, Youm Y, Kim J, Chey J, Kwak S, Parkinson C (2020).  Similarity in functional brain connectivity at rest predicts interpersonal closeness in the social network of an entire village.  PNAS 117(52):33149-33160.  
  • Inbal also will discuss a related project that she currently is working on.  

15 April 2025:  Free-for-all discussion  

  • Background info:  Barb Finlay is delivering the Gibson Lecture on Friday 18 April at 3:00 pm.  The evening before, there will be a Gibson Seminar and catered dinner starting at 5:00 pm on April 17 in Uris 204.  In traditional BBS style, the focus is on grad students, but all can attend.  If you intend to go to the April 17th evening dinner seminar, please RSVP at this link, ideally by this Friday 11 April.  The official announcement was emailed out on Tuesday 4/8 with subject line "Gibson lecture and grad student seminar".  
  • At the evening Gibson Seminar, two of Barb's papers will be discussed, and we'll delve into broader issues of theory, data, and comparative work with her.  We at the CNS JC would like to read the same papers, a couple days ahead, in order to get into them early and hence improve the quality of our discussions with Barb on Thursday.  So, we will discuss both of them in CNS JC on April 15.  Here they are:
  • MacIver, M.A. & Finlay, B.L (2021). The neuroecology of the water-to-land transition, and the evolution of the vertebrate brain.  Proceedings of the Royal Society of Britain B: Biological Sciences 377: 20200523.  doi:10.1098/rstb.2020.0523. 
  • Imam, N. & Finlay, B.L (2020). Self-organization of cortical areas in the development and evolution of neocortex: a network growth model. Proceedings of the National Academy of Sciences (USA) 117: 29212-29220.  doi:10.1073/pnas.2011724117.

So as we all learned today, "mitochondrial heterogeneity" usually means different numbers/densities of mitochondria being present in different cells or volumes of tissue from different regions of (in our case) the brain... but it also can mean actual differences in the properties of individual mitochondria, or classes of mitochondria.  Or so it seems.  Should you wish to dig into this, here are a couple of reviews that may be of interest:
