[Koglist] Fluencia Party on 9th February (Friday)

by Dezso Nemeth

Dear Cognitive Folks, The next Fluencia Party will be on 9th February (Friday) starting at 8.00pm in Élesztő (Tűzoltó utca close to Corvin metro station). Info: https://www.facebook.com/events/2013110232260580/ Fluencia is a monthly organized informal "jamboree" for cogsci-, psychology-related students (undergrads, grads), professors, researchers from many different universities in Hungary. The idea and motivation are to facilitate interactions, communication, collaboration among researchers working here, get to know others and others' interests, topics, etc. And, of course, to have some drinks and fun in a friendly environment. Everybody is welcome to attend! If you have any further questions, do not hesitate to ask. All the best, Dezso -------------------------------------- NEMETH, Dezso (PhD) Brain, Memory and Language Lab: http://www.memory-and-language.com Phone: +36-1-4614500/3565, +36-1-4614500/3519

[Koglist] Cognitive Seminar

by Kelemen Alexandra

Dear all, We would like to invite you to the following talk by Enikő Kubinyi (Department of Ethology, ELTE) organized as part of the ELTE Cognitive Seminar series. Time and date: 17:00 (CET), Tuesday, 07 November 2023 Location: 1064 Budapest, Izabella 46, 206 room Speaker: Enikő Kubinyi, PhD, DSc (Department of Ethology, ELTE) Title: Canine cognitive aging and the changing role of dogs in Western societies Abstract: Understanding active, healthy aging is a pressing concern, and companion dog aging research offers unique insights. Our Senior Family Dog Project aimed to explore the cognitive aging of family dogs using an interdisciplinary approach with behavioral, neuroscientific, and genetic testing methods. We found similarities with humans in the age-related changes, such as personality traits, the "positivity effect," sleep spindles, association between memory performance and gut microbiome, genetic mutations related to longevity, age-related alterations of the mRNA transcriptome, and a positive correlation between age, cognitive dysfunction score, and amyloid-beta 42, an Alzheimer's disease-associated peptide in the brain. This research can contribute to translational studies, advance canine welfare and raise awareness of how important dogs are to owners. As the number of dogs increases while the number of children remains stable or decreases in Western societies, a cultural shift occurs. In our new research program, we study why more people are turning to dogs for "unconditional love" as loneliness becomes more prevalent. Historically, people depended on their kin for survival, but due to demographic transitions and cultural reinforcement, people's strong innate preference for social proximity and nurturing group members has partly shifted towards pets. Our theory offers a cultural evolutionary framework for understanding the role of dogs in Western societies and how this role might impact both human and pet populations. Caring for pets may reduce opportunities and the desire to care for children and other humans. On the other hand, treating pets as "furry kids" can lead to health and behavioral problems in dogs. If you have questions about the event, please contact us via email (alexastonem(a)student.elte.hu or reka.schvajda(a)ppk.elte.hu). We look forward to seeing you at the event, Alexandra Kelemen Réka Schvajda organizers ELTE Department of Cognitive Psychology

[Koglist] [CEU Cogsci Talks] Reminder - Budapest Computational Neuroscience Forum - Oct. 25.

by Ildiko Zsoka Varga

Dear All, The CEU Department of Cognitive Science and the Center for Cognitive Computation (CCC) invites you to the upcoming meeting of the Budapest Computational Neuroscience Forum<https://ccc.ceu.edu/budapest-computational-neuroscience-forum>. Speaker: Ferenc Csikor, Wigner Institute<https://wigner.hu/en/infopages/csikor.ferenc> Top-down perceptual inference shaping the activity of early visual cortex Deep discriminative models have recently provided remarkable insights into hierarchical processing in the brain by predicting neural activity along the visual ventral pathway. However, these models are at odds with biological systems both at the computational and architectural levels: on the computational level, deep discriminative models rely on supervised learning, which necessitates exhaustive labeling of experiences; and on architectural level, these models are fundamentally feed-forward in processing incoming stimuli, in contrast with the ventral pathway that is characterized by extensive top-down connectivity. Here, we address these issues by developing a hierarchical deep generative model of natural images and show that it can predict an extensive set of experimental results in the primary and secondary visual cortices (V1 and V2, respectively). Our analysis shows that sensitivity of V2 neurons to subtle changes of high-level statistics of images is a consequence of learning a hierarchical representation of natural images. Further, we show that top-down influences are natural ingredients of hierarchical generative models, and a range of experimental phenomena concerning the mean responses and noise correlation structure of V1 responses are a consequence of inference in this generative model. Time: 17:00, October 25, 2023. Location: CEU, 1051 Bp. Nádor u. 15, FT. room 408. (restricted entry, guest cards will be available at the reception) and Zoom (Meeting ID: 913 1139 5317<https://ceu-edu.zoom.us/j/91311395317?pwd=eFhHRkNkSWw0OXhyT1JBb2tVTkZWUT09> Passcode: 290844) Should you have any inquiries about the series, please contact Mihály Bányai<mailto:mihaly.s.banyai@gmail.com>.
