The Cognition and Neural Systems (CNS) Journal Club meets on Tuesdays from 11:45 to 1:00 pm in Uris Hall 205.
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 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 BCS-L mailing list, send a plain-text email to bcs-L-request@cornell.edu with the body of the message saying simply join. The subject line doesn't matter. Sending the message leave instead will unsubscribe you from the list. See Cornell's Lyris HowTo page for further details.
You can enroll in the BCS Journal Club for graduate or undergraduate credit (1 CR, S/U) as a Topics in Biopsychology seminar: PSYCH 6271. 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.

S. Warren, E. Yacoub & G. Ghose (2014). Featural and temporal attention selectively enhance task-appropriate representations in human primary visual cortex. Nature Communications 5:5643.
This paper highlights two basic points that are important for anyone who cares about how brains work. First, attention alters the behavior of neuronal populations. As a result, tasks can impact what is represented and measured. Second, what is represented by neuronal populations is influenced by expectations along multiple dimensions, including visual features, timing, and semantics (not just space).

This paper can serve as a starting point for a discussion of species recognition mechanisms in general, brood parasitism behavior, vocal learning and call production and their related auditory and production brain regions, ZENK as a scientific tool, innate vs. learned behaviors (and the potential false dichotomy of that distinction), and in vivo/in ovo learning.
24 October 2017: George Prounis
M. Stephenson-Jones, K. Yu, S. Ahrens, J. Tucciarone, A. van Huijstee, L. Mejia, M. Penzo, L. Tai, L. Wilbrecht & B. Li (2016). A basal ganglia circuit for evaluating action outcomes. Nature 539:289-293.

These papers highlight the dynamic role of basal ganglia dopamine systems in decision-making and action evaluation in mice. The authors bi-directionally influence reward-based decisions via optogenetic manipulation of specific neuronal populations within the basal ganglia. Overall, these papers demonstrate the 1) the importance of dopamine in both evaluation and action, and 2) the explanatory power of linking precise, sub-circuit neural manipulations to simple behavioral tasks. My research interests include developmental changes in decision-making circuits, particularly the involvement of dopamine systems during adolescent risk-taking behavior.

A. Broitman, M. Kahana and M. Healey (submitted). Modeling Retest Effects in a Longitudinal Measurement Burst Design Study of Episodic Memory.
This paper proposes a mathematical model with which to separate age-related memory changes from task-specific retest effects in a longitudinal study. This paper may be useful to anyone who conducts long-term human cognition studies, and I will discuss its potential application to my future work.
