Modulation of aggression by social novelty recognition memory in the hippocampal CA2 region

Posted by dbos Columbia

Kavli Affiliate: Steven Siegelbaum | Authors: Andres Villegas and Steven A Siegelbaum | Summary: The dorsal CA2 subregion (dCA2) of the hippocampus exerts a critical role in social novelty recognition (SNR) memory and in the promotion of social aggression. Whether the social aggression and SNR memory functions of dCA2 are related or represent independent processes […]

Two routes to value-based decisions in Parkinsons disease: differentiating incremental reinforcement learning from episodic memory

Posted by dbos Columbia

Kavli Affiliate: Daphna Shohamy | Authors: Peter Jendrichovsky, Hey-Kyoung Lee and Patrick O Kanold | Summary: Patients with Parkinsons disease are impaired at incremental reward-based learning. It is typically assumed that this impairment reflects a loss of striatal dopamine. However, many open questions remain about the nature of reward-based learning deficits in Parkinsons. Recent studies […]

Dark exposure reduces high-frequency hearing loss in C57BL/6J mice

Posted by dbos Hopkins

Kavli Affiliate: Hey-Kyoung Lee and Patrick Kanold | Authors: Peter Jendrichovsky, Hey-Kyoung Lee and Patrick O Kanold | Summary: Plastic changes in the brain are primarily limited to early postnatal periods. Recovery of adult brain plasticity is critical for the effective development of therapies. A brief (1-2 week) duration of visual deprivation (dark exposure, DE) […]

Coordination and persistence of aggressive visual communication in Siamese fighting fish

Posted by dbos Columbia

Kavli Affiliate: Liam Paninski | Authors: Claire P. Everett, Amy L. Norovich, Jessica E. Burke, Matthew R Whiteway, Pei-Yin Shih, Yuyang Zhu, Liam Paninski and Andres Bendesky | Summary: Animals coordinate their behavior with each other during both cooperative and agonistic social interactions. Such coordination often adopts the form of “turn taking”, in which the […]

Distinct anatomical and functional corticospinal inputs innervate different spinal neuron types

Posted by dbos Columbia

Kavli Affiliate: Liam Paninski | Authors: Samaher Fageiry, Claire L Warriner, Jackson Loper, Liam Paninski, Thomas Reardon, Thomas M. Jessell, Rui M. Costa and Andrew Miri | Summary: The corticospinal tract exerts its influence on movement through spinal neurons, which can be divided into types that exhibit distinct functions. However, it remains unknown whether these […]

The breath shape controls intonation of mouse vocalizations

Posted by dbos UCSF

Kavli Affiliate: Kevin Yackle | Authors: Alastair MacDonald and Kevin Yacklei | Summary: Intonation in speech is the control of vocal pitch to layer expressive meaning to communication, like increasing pitch to indicate a question. Also, stereotyped patterns of pitch are used to create distinct “words”, like the ten sounds in the murine lexicon. A […]

Dynamical Responses Predict a Distal Site that Modulates Activity in an Antibiotic Resistance Enzyme

Posted by dbos Hopkins

Kavli Affiliate: Michael Beer | Authors: Michael Beer, Ana Sofia F. Oliveira, Catherine L. Tooke, Philip Hinchliffe, Angie Tsz Yan Li, Balazs Balega, James Spencer and Adrian J Mulholland | Summary: β-Lactamases, which hydrolyse β-lactam antibiotics, are key determinants of antibiotic resistance. Predicting the sites and effects of distal mutations in enzymes is challenging. For […]
