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 graduate students enrolling if you plan to attend the whole semester and to present.

Please contact Thomas Cleland or , David Smith, or Marlen Gonzalez with any questions.

• 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.

22 April 2025:  Cancelled - enjoy your free hour

29 April 2025:  David Smith - The role of the retrosplenial cortex, as revealed by studies using the T-maze.

• Mosharov EV, et al. (2025). A human brain map of mitochondrial respiratory capacity and diversity.  Nature.  https://doi.org/10.1038/s41586-025-08740-6.

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:

• Granath-Panelo M, Kajimura S (2024).  Mitochondrial heterogeneity and adaptations to cellular needs.  Nat Cell Biol 26(5):674-686.
• Pekkurnaz G, Wang X (2022).  Mitochondrial heterogeneity and homeostasis through the lens of a neuron.  Nat Metab 4(7): 802-812.  
• ... and many more...
