Supervised Learning and Large Language Model Benchmarks on Mental Health Datasets: Cognitive Distortions and Suicidal Risks in Chinese Social Media

Posted by dbos Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Hongzhi Qi, Qing Zhao, Changwei Song, Wei Zhai, Dan Luo | Summary: In the realm of social media, users frequently convey personal sentiments, with some potentially indicating cognitive distortions or suicidal tendencies. Timely recognition of such signs is pivotal for effective interventions. In response, we introduce two […]

Evaluating the Efficacy of Supervised Learning vs Large Language Models for Identifying Cognitive Distortions and Suicidal Risks in Chinese Social Media

Posted by klaurent Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Hongzhi Qi, Qing Zhao, Changwei Song, Wei Zhai, Dan Luo | Summary: Large language models, particularly those akin to the rapidly progressing GPT series, are gaining traction for their expansive influence. While there is keen interest in their applicability within medical domains such as psychology, tangible explorations […]

Drugs of abuse hijack a mesolimbic pathway that processes homeostatic need

Posted by klaurent Rockefeller

Kavli Affiliate: Alipasha Vaziri, Jeffrey M. Friedman | Authors: Bowen Tan, Caleb J Browne, Tobias Nobauer, Alipasha Vaziri, Jeffrey M. Friedman and Eric J. Nestler | Summary: Addiction prioritizes drug use over innate needs by hijacking brain circuits that direct motivation, but how this develops remains unclear. Using whole-brain FOS mapping and in vivo single-neuron […]

Virion-associated US28 rapidly modulates Akt activity to suppress HCMV lytic replication in monocytes

Posted by klaurent Hopkins

Kavli Affiliate: Michael Miller | Authors: Jamil Mahmud, Brittany W Geiler, Juthi Biswas, Michael J Miller, Julia E Myers, Stephen M Matthews, Amanda B Wass, Christine M O’Connor and Gary C Chan | Summary: Establishing a non-productive quiescent/silent infection within monocytes is essential for spread of human cytomegalovirus (HCMV). Yet, how HCMV establishes a quiescent […]

Reward expectation selectively boosts the firing of accumbens D1+ neurons during motivated approach

Posted by klaurent UCSF

Kavli Affiliate: Joshua Berke | Authors: Thomas Faust, Ali Mohebi and Joshua D Berke | Summary: The nucleus accumbens (NAc) helps govern motivation to pursue rewards. Two distinct sets of NAc projection neurons – expressing dopamine D1 versus D2 receptors – are thought to promote and suppress motivated behaviors respectively. However, support for this conceptual […]

Costs of resistance limit the effectiveness of cooperation enforcement

Posted by klaurent Hopkins

Kavli Affiliate: Michael Miller | Authors: Michael E Miller, Susan Sidell and Elizabeth A Ostrowski | Summary: Cooperative groups are susceptible to invasion by cheaters that reap the benefits but fail to pay the costs. Both theory and experimental work have shown that cheating can select for counter-adaptations to resist cheating. But then why is […]

Laws for Glia Organization Conserved Across Mammals

Posted by klaurent UCSD / Salk

Kavli Affiliate: Terrence Sejnowski | Authors: Antonio Pinto-Duarte, Katharine Bogue, Terrence J. Sejnowski and Shyam Srinivasan | Summary: The organizational principles of glia remain largely unknown despite their vital role in nervous system function. Previous work has shown that the number of glia per unit volume of neocortex is constant across mammalian species. We hypothesize […]
